-                    GNU GENERAL PUBLIC LICENSE
-                       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                            Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-                            NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License along
-    with this program; if not, write to the Free Software Foundation, Inc.,
-    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) year name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Lesser General
-Public License instead of this License.

-                    GNU GENERAL PUBLIC LICENSE
-                       Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                            Preamble
-
-  The GNU General Public License is a free, copyleft license for
-software and other kinds of works.
-
-  The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works.  By contrast,
-the GNU General Public License is intended to guarantee your freedom to
-share and change all versions of a program--to make sure it remains free
-software for all its users.  We, the Free Software Foundation, use the
-GNU General Public License for most of our software; it applies also to
-any other work released this way by its authors.  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.
-
-  To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights.  Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received.  You must make sure that they, too, receive
-or can get the source code.  And you must show them these terms so they
-know their rights.
-
-  Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
-
-  For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software.  For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
-  Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so.  This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software.  The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable.  Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products.  If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
-  Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary.  To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                       TERMS AND CONDITIONS
-
-  0. Definitions.
-
-  "This License" refers to version 3 of the GNU General Public License.
-
-  "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
-  "The Program" refers to any copyrightable work licensed under this
-License.  Each licensee is addressed as "you".  "Licensees" and
-"recipients" may be individuals or organizations.
-
-  To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy.  The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
-  A "covered work" means either the unmodified Program or a work based
-on the Program.
-
-  To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy.  Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
-  To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies.  Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
-  An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License.  If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
-  1. Source Code.
-
-  The "source code" for a work means the preferred form of the work
-for making modifications to it.  "Object code" means any non-source
-form of a work.
-
-  A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
-  The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form.  A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
-  The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities.  However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work.  For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
-  The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
-  The Corresponding Source for a work in source code form is that
-same work.
-
-  2. Basic Permissions.
-
-  All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met.  This License explicitly affirms your unlimited
-permission to run the unmodified Program.  The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work.  This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
-  You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force.  You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright.  Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
-  Conveying under any other circumstances is permitted solely under
-the conditions stated below.  Sublicensing is not allowed; section 10
-makes it unnecessary.
-
-  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
-  No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
-  When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
-  4. Conveying Verbatim Copies.
-
-  You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
-  You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
-  5. Conveying Modified Source Versions.
-
-  You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
-    a) The work must carry prominent notices stating that you modified
-    it, and giving a relevant date.
-
-    b) The work must carry prominent notices stating that it is
-    released under this License and any conditions added under section
-    7.  This requirement modifies the requirement in section 4 to
-    "keep intact all notices".
-
-    c) You must license the entire work, as a whole, under this
-    License to anyone who comes into possession of a copy.  This
-    License will therefore apply, along with any applicable section 7
-    additional terms, to the whole of the work, and all its parts,
-    regardless of how they are packaged.  This License gives no
-    permission to license the work in any other way, but it does not
-    invalidate such permission if you have separately received it.
-
-    d) If the work has interactive user interfaces, each must display
-    Appropriate Legal Notices; however, if the Program has interactive
-    interfaces that do not display Appropriate Legal Notices, your
-    work need not make them do so.
-
-  A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit.  Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
-  6. Conveying Non-Source Forms.
-
-  You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
-    a) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by the
-    Corresponding Source fixed on a durable physical medium
-    customarily used for software interchange.
-
-    b) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by a
-    written offer, valid for at least three years and valid for as
-    long as you offer spare parts or customer support for that product
-    model, to give anyone who possesses the object code either (1) a
-    copy of the Corresponding Source for all the software in the
-    product that is covered by this License, on a durable physical
-    medium customarily used for software interchange, for a price no
-    more than your reasonable cost of physically performing this
-    conveying of source, or (2) access to copy the
-    Corresponding Source from a network server at no charge.
-
-    c) Convey individual copies of the object code with a copy of the
-    written offer to provide the Corresponding Source.  This
-    alternative is allowed only occasionally and noncommercially, and
-    only if you received the object code with such an offer, in accord
-    with subsection 6b.
-
-    d) Convey the object code by offering access from a designated
-    place (gratis or for a charge), and offer equivalent access to the
-    Corresponding Source in the same way through the same place at no
-    further charge.  You need not require recipients to copy the
-    Corresponding Source along with the object code.  If the place to
-    copy the object code is a network server, the Corresponding Source
-    may be on a different server (operated by you or a third party)
-    that supports equivalent copying facilities, provided you maintain
-    clear directions next to the object code saying where to find the
-    Corresponding Source.  Regardless of what server hosts the
-    Corresponding Source, you remain obligated to ensure that it is
-    available for as long as needed to satisfy these requirements.
-
-    e) Convey the object code using peer-to-peer transmission, provided
-    you inform other peers where the object code and Corresponding
-    Source of the work are being offered to the general public at no
-    charge under subsection 6d.
-
-  A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
-  A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling.  In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage.  For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product.  A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
-  "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source.  The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
-  If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information.  But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
-  The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed.  Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
-  Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
-  7. Additional Terms.
-
-  "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law.  If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
-  When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it.  (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.)  You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
-  Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
-    a) Disclaiming warranty or limiting liability differently from the
-    terms of sections 15 and 16 of this License; or
-
-    b) Requiring preservation of specified reasonable legal notices or
-    author attributions in that material or in the Appropriate Legal
-    Notices displayed by works containing it; or
-
-    c) Prohibiting misrepresentation of the origin of that material, or
-    requiring that modified versions of such material be marked in
-    reasonable ways as different from the original version; or
-
-    d) Limiting the use for publicity purposes of names of licensors or
-    authors of the material; or
-
-    e) Declining to grant rights under trademark law for use of some
-    trade names, trademarks, or service marks; or
-
-    f) Requiring indemnification of licensors and authors of that
-    material by anyone who conveys the material (or modified versions of
-    it) with contractual assumptions of liability to the recipient, for
-    any liability that these contractual assumptions directly impose on
-    those licensors and authors.
-
-  All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10.  If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term.  If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
-  If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
-  Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
-  8. Termination.
-
-  You may not propagate or modify a covered work except as expressly
-provided under this License.  Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
-  However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
-  Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-  Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
-  9. Acceptance Not Required for Having Copies.
-
-  You are not required to accept this License in order to receive or
-run a copy of the Program.  Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance.  However,
-nothing other than this License grants you permission to propagate or
-modify any covered work.  These actions infringe copyright if you do
-not accept this License.  Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
-  10. Automatic Licensing of Downstream Recipients.
-
-  Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License.  You are not responsible
-for enforcing compliance by third parties with this License.
-
-  An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations.  If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
-  You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License.  For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
-  11. Patents.
-
-  A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based.  The
-work thus licensed is called the contributor's "contributor version".
-
-  A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version.  For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
-  Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
-  In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement).  To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
-  If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients.  "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
-  If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
-  A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License.  You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
-  Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
-  12. No Surrender of Others' Freedom.
-
-  If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all.  For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
-  13. Use with the GNU Affero General Public License.
-
-  Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU Affero General Public License into a single
-combined work, and to convey the resulting work.  The terms of this
-License will continue to apply to the part which is the covered work,
-but the special requirements of the GNU Affero General Public License,
-section 13, concerning interaction through a network will apply to the
-combination as such.
-
-  14. Revised Versions of this License.
-
-  The Free Software Foundation may publish revised and/or new versions of
-the GNU General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-  Each version is given a distinguishing version number.  If the
-Program specifies that a certain numbered version of the GNU General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation.  If the Program does not specify a version number of the
-GNU General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
-  If the Program specifies that a proxy can decide which future
-versions of the GNU General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
-  Later license versions may give you additional or different
-permissions.  However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
-  15. Disclaimer of Warranty.
-
-  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. Limitation of Liability.
-
-  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
-  17. Interpretation of Sections 15 and 16.
-
-  If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software: you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation, either version 3 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program.  If not, see <http://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
-  If the program does terminal interaction, make it output a short
-notice like this when it starts in an interactive mode:
-
-    <program>  Copyright (C) <year>  <name of author>
-    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, your program's commands
-might be different; for a GUI interface, you would use an "about box".
-
-  You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.
-For more information on this, and how to apply and follow the GNU GPL, see
-<http://www.gnu.org/licenses/>.
-
-  The GNU General Public License does not permit incorporating your program
-into proprietary programs.  If your program is a subroutine library, you
-may consider it more useful to permit linking proprietary applications with
-the library.  If this is what you want to do, use the GNU Lesser General
-Public License instead of this License.  But first, please read
-<http://www.gnu.org/philosophy/why-not-lgpl.html>.

-                  GNU LESSER GENERAL PUBLIC LICENSE
-                       Version 2.1, February 1999
-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the Lesser GPL.  It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
-
-                            Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
-  This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it.  You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations below.
-
-  When we speak of free software, we are referring to freedom of use,
-not price.  Our General Public Licenses are designed to make sure that
-you have the freedom to distribute copies of free software (and charge
-for this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
-  To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights.  These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
-  For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you.  You must make sure that they, too, receive or can get the source
-code.  If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it.  And you must show them these terms so they know their rights.
-
-  We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
-  To protect each distributor, we want to make it very clear that
-there is no warranty for the free library.  Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-
-  Finally, software patents pose a constant threat to the existence of
-any free program.  We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder.  Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
-  Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License.  This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License.  We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
-  When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library.  The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom.  The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
-  We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License.  It also provides other free software developers Less
-of an advantage over competing non-free programs.  These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries.  However, the Lesser license provides advantages in certain
-special circumstances.
-
-  For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it becomes
-a de-facto standard.  To achieve this, non-free programs must be
-allowed to use the library.  A more frequent case is that a free
-library does the same job as widely used non-free libraries.  In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
-  In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software.  For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
-  Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.  Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library".  The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.

-  A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-  The "Library", below, refers to any such software library or work
-which has been distributed under these terms.  A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language.  (Hereinafter, translation is
-included without limitation in the term "modification".)
-
-  "Source code" for a work means the preferred form of the work for
-making modifications to it.  For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
-  Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it).  Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-
-  1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
-  You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
-  2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) The modified work must itself be a software library.
-
-    b) You must cause the files modified to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    c) You must cause the whole of the work to be licensed at no
-    charge to all third parties under the terms of this License.
-
-    d) If a facility in the modified Library refers to a function or a
-    table of data to be supplied by an application program that uses
-    the facility, other than as an argument passed when the facility
-    is invoked, then you must make a good faith effort to ensure that,
-    in the event an application does not supply such function or
-    table, the facility still operates, and performs whatever part of
-    its purpose remains meaningful.
-
-    (For example, a function in a library to compute square roots has
-    a purpose that is entirely well-defined independent of the
-    application.  Therefore, Subsection 2d requires that any
-    application-supplied function or table used by this function must
-    be optional: if the application does not supply it, the square
-    root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library.  To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License.  (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.)  Do not make any other change in
-these notices.
-
-  Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-  This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
-  4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
-  If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library".  Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
-  However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library".  The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
-  When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library.  The
-threshold for this to be true is not precisely defined by law.
-
-  If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work.  (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
-  Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
-  6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
-  You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License.  You must supply a copy of this License.  If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License.  Also, you must do one
-of these things:
-
-    a) Accompany the work with the complete corresponding
-    machine-readable source code for the Library including whatever
-    changes were used in the work (which must be distributed under
-    Sections 1 and 2 above); and, if the work is an executable linked
-    with the Library, with the complete machine-readable "work that
-    uses the Library", as object code and/or source code, so that the
-    user can modify the Library and then relink to produce a modified
-    executable containing the modified Library.  (It is understood
-    that the user who changes the contents of definitions files in the
-    Library will not necessarily be able to recompile the application
-    to use the modified definitions.)
-
-    b) Use a suitable shared library mechanism for linking with the
-    Library.  A suitable mechanism is one that (1) uses at run time a
-    copy of the library already present on the user's computer system,
-    rather than copying library functions into the executable, and (2)
-    will operate properly with a modified version of the library, if
-    the user installs one, as long as the modified version is
-    interface-compatible with the version that the work was made with.
-
-    c) Accompany the work with a written offer, valid for at
-    least three years, to give the same user the materials
-    specified in Subsection 6a, above, for a charge no more
-    than the cost of performing this distribution.
-
-    d) If distribution of the work is made by offering access to copy
-    from a designated place, offer equivalent access to copy the above
-    specified materials from the same place.
-
-    e) Verify that the user has already received a copy of these
-    materials or that you have already sent this user a copy.
-
-  For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it.  However, as a special exception,
-the materials to be distributed need not include anything that is
-normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
-  It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system.  Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
-  7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
-    a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities.  This must be distributed under the terms of the
-    Sections above.
-
-    b) Give prominent notice with the combined library of the fact
-    that part of it is a work based on the Library, and explaining
-    where to find the accompanying uncombined form of the same work.
-
-  8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License.  Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License.  However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
-  9. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Library or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-  10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties with
-this License.
-
-  11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded.  In such case, this License incorporates the limitation as if
-written in the body of this License.
-
-  13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation.  If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
-  14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission.  For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this.  Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
-                            NO WARRANTY
-
-  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
-                     END OF TERMS AND CONDITIONS
-
-           How to Apply These Terms to Your New Libraries
-
-  If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change.  You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of the
-ordinary General Public License).
-
-  To apply these terms, attach the following notices to the library.  It is
-safest to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the library's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This library is free software; you can redistribute it and/or
-    modify it under the terms of the GNU Lesser General Public
-    License as published by the Free Software Foundation; either
-    version 2.1 of the License, or (at your option) any later version.
-
-    This library is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
-    Lesser General Public License for more details.
-
-    You should have received a copy of the GNU Lesser General Public
-    License along with this library; if not, write to the Free Software
-    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
-
-Also add information on how to contact you by electronic and paper mail.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the library, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the
-  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
-
-  <signature of Ty Coon>, 1 April 1990
-  Ty Coon, President of Vice

-That's all there is to it!

-                       Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-
-  This version of the GNU Lesser General Public License incorporates
-the terms and conditions of version 3 of the GNU General Public
-License, supplemented by the additional permissions listed below.
-
-  0. Additional Definitions.
-
-  As used herein, "this License" refers to version 3 of the GNU Lesser
-General Public License, and the "GNU GPL" refers to version 3 of the GNU
-General Public License.
-
-  "The Library" refers to a covered work governed by this License,
-other than an Application or a Combined Work as defined below.
-
-  An "Application" is any work that makes use of an interface provided
-by the Library, but which is not otherwise based on the Library.
-Defining a subclass of a class defined by the Library is deemed a mode
-of using an interface provided by the Library.
-
-  A "Combined Work" is a work produced by combining or linking an
-Application with the Library.  The particular version of the Library
-with which the Combined Work was made is also called the "Linked
-Version".
-
-  The "Minimal Corresponding Source" for a Combined Work means the
-Corresponding Source for the Combined Work, excluding any source code
-for portions of the Combined Work that, considered in isolation, are
-based on the Application, and not on the Linked Version.
-
-  The "Corresponding Application Code" for a Combined Work means the
-object code and/or source code for the Application, including any data
-and utility programs needed for reproducing the Combined Work from the
-Application, but excluding the System Libraries of the Combined Work.
-
-  1. Exception to Section 3 of the GNU GPL.
-
-  You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-
-  2. Conveying Modified Versions.
-
-  If you modify a copy of the Library, and, in your modifications, a
-facility refers to a function or data to be supplied by an Application
-that uses the facility (other than as an argument passed when the
-facility is invoked), then you may convey a copy of the modified
-version:
-
-   a) under this License, provided that you make a good faith effort to
-   ensure that, in the event an Application does not supply the
-   function or data, the facility still operates, and performs
-   whatever part of its purpose remains meaningful, or
-
-   b) under the GNU GPL, with none of the additional permissions of
-   this License applicable to that copy.
-
-  3. Object Code Incorporating Material from Library Header Files.
-
-  The object code form of an Application may incorporate material from
-a header file that is part of the Library.  You may convey such object
-code under terms of your choice, provided that, if the incorporated
-material is not limited to numerical parameters, data structure
-layouts and accessors, or small macros, inline functions and templates
-(ten or fewer lines in length), you do both of the following:
-
-   a) Give prominent notice with each copy of the object code that the
-   Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the object code with a copy of the GNU GPL and this license
-   document.
-
-  4. Combined Works.
-
-  You may convey a Combined Work under terms of your choice that,
-taken together, effectively do not restrict modification of the
-portions of the Library contained in the Combined Work and reverse
-engineering for debugging such modifications, if you also do each of
-the following:
-
-   a) Give prominent notice with each copy of the Combined Work that
-   the Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the Combined Work with a copy of the GNU GPL and this license
-   document.
-
-   c) For a Combined Work that displays copyright notices during
-   execution, include the copyright notice for the Library among
-   these notices, as well as a reference directing the user to the
-   copies of the GNU GPL and this license document.
-
-   d) Do one of the following:
-
-       0) Convey the Minimal Corresponding Source under the terms of this
-       License, and the Corresponding Application Code in a form
-       suitable for, and under terms that permit, the user to
-       recombine or relink the Application with a modified version of
-       the Linked Version to produce a modified Combined Work, in the
-       manner specified by section 6 of the GNU GPL for conveying
-       Corresponding Source.
-
-       1) Use a suitable shared library mechanism for linking with the
-       Library.  A suitable mechanism is one that (a) uses at run time
-       a copy of the Library already present on the user's computer
-       system, and (b) will operate properly with a modified version
-       of the Library that is interface-compatible with the Linked
-       Version.
-
-   e) Provide Installation Information, but only if you would otherwise
-   be required to provide such information under section 6 of the
-   GNU GPL, and only to the extent that such information is
-   necessary to install and execute a modified version of the
-   Combined Work produced by recombining or relinking the
-   Application with a modified version of the Linked Version. (If
-   you use option 4d0, the Installation Information must accompany
-   the Minimal Corresponding Source and Corresponding Application
-   Code. If you use option 4d1, you must provide the Installation
-   Information in the manner specified by section 6 of the GNU GPL
-   for conveying Corresponding Source.)
-
-  5. Combined Libraries.
-
-  You may place library facilities that are a work based on the
-Library side by side in a single library together with other library
-facilities that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
-
-   a) Accompany the combined library with a copy of the same work based
-   on the Library, uncombined with any other library facilities,
-   conveyed under the terms of this License.
-
-   b) Give prominent notice with the combined library that part of it
-   is a work based on the Library, and explaining where to find the
-   accompanying uncombined form of the same work.
-
-  6. Revised Versions of the GNU Lesser General Public License.
-
-  The Free Software Foundation may publish revised and/or new versions
-of the GNU Lesser General Public License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.
-
-  Each version is given a distinguishing version number. If the
-Library as you received it specifies that a certain numbered version
-of the GNU Lesser General Public License "or any later version"
-applies to it, you have the option of following the terms and
-conditions either of that published version or of any later version
-published by the Free Software Foundation. If the Library as you
-received it does not specify a version number of the GNU Lesser
-General Public License, you may choose any version of the GNU Lesser
-General Public License ever published by the Free Software Foundation.
-
-  If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.

-FFmpeg:
--------
-
-Most files in FFmpeg are under the GNU Lesser General Public License version 2.1
-or later (LGPL v2.1+). Read the file COPYING.LGPLv2.1 for details. Some other
-files have MIT/X11/BSD-style licenses. In combination the LGPL v2.1+ applies to
-FFmpeg.
-
-Some optional parts of FFmpeg are licensed under the GNU General Public License
-version 2 or later (GPL v2+). See the file COPYING.GPLv2 for details. None of
-these parts are used by default, you have to explicitly pass --enable-gpl to
-configure to activate them. In this case, FFmpeg's license changes to GPL v2+.
-
-Specifically, the GPL parts of FFmpeg are
-
-- libpostproc
-- optional x86 optimizations in the files
-  libavcodec/x86/idct_mmx.c
-- the X11 grabber in libavdevice/x11grab.c
-
-There are a handful of files under other licensing terms, namely:
-
-* The files libavcodec/jfdctfst.c, libavcodec/jfdctint.c, libavcodec/jrevdct.c
-  are taken from libjpeg, see the top of the files for licensing details.
-
-Should you, for whatever reason, prefer to use version 3 of the (L)GPL, then
-the configure parameter --enable-version3 will activate this licensing option
-for you. Read the file COPYING.LGPLv3 or, if you have enabled GPL parts,
-COPYING.GPLv3 to learn the exact legal terms that apply in this case.
-
-
-external libraries:
--------------------
-
-Some external libraries, e.g. libx264, are under GPL and can be used in
-conjunction with FFmpeg. They require --enable-gpl to be passed to configure
-as well.
-
-The OpenCORE external libraries are under the Apache License 2.0. That license
-is incompatible with the LGPL v2.1 and the GPL v2, but not with version 3 of
-those licenses. So to combine the OpenCORE libraries with FFmpeg, the license
-version needs to be upgraded by passing --enable-version3 to configure.
-
-The nonfree external libraries libfaac and libaacplus can be hooked up in FFmpeg.
-You need to pass --enable-nonfree to configure to enable it. Employ this option
-with care as FFmpeg then becomes nonfree and unredistributable.

-Release Notes
-=============
-
-* 0.8 "Love"  June, 2011
-* 0.7.1 "Peace" June, 2011 (identical to 0.8 but using 0.6 ABI/API)
-
-
-General notes
--------------
-
-This release enables frame-based multithreaded decoding for a number of codecs,
-including theora, huffyuv, VP8, H.263, mpeg4 and H.264. Additionally, there has
-been a major cleanup of
-both internal and external APIs. For this reason, the major versions of all
-libraries except libpostproc have been bumped. This means that 0.8 can be installed
-side-by-side with previous releases, on the other hand applications need to be
-recompiled to use 0.8.
-
-Other important changes are more than 200 bugfixes, known regressions were fixed
-w.r.t 0.5 and 0.6, additions of decoders including, but not limited to,
-AMR-WB, single stream LATM/LOAS, G.722 ADPCM, a native VP8 decoder
-and HE-AACv2. Additionally, many new de/muxers such as WebM in Matroska, Apple
-HTTP Live Streaming, SAP, IEC 61937 (S/PDIF) have been added.
-
-See the Changelog file for a list of significant changes.
-
-Bugreports against FFmpeg git master or the most recent FFmpeg release are
-accepted. If you are experiencing issues with any formally released version of
-FFmpeg, please try git master to check if the issue still exists. If it does,
-make your report against the development code following the usual bug reporting
-guidelines.
-
-Note, if you have difficulty building for mingw, try --disable-outdev=sdl
-
-
-API changes
------------
-
-Please see git log of the public headers or the file doc/APIchanges for
-programmer-centric information. Note that some long-time deprecated APIs have
-been removed. Also, a number of additional APIs have been deprecated and might
-be removed in the next release.
-
-
-Other notable changes
----------------------

-
-When you configure your FFmpeg build, all the supported bitstream
-filters are enabled by default. You can list all available ones using
-the configure option @code{--list-bsfs}.
-
-You can disable all the bitstream filters using the configure option
-@code{--disable-bsfs}, and selectively enable any bitstream filter using
-the option @code{--enable-bsf=BSF}, or you can disable a particular
-bitstream filter using the option @code{--disable-bsf=BSF}.
-
-The option @code{-bsfs} of the ff* tools will display the list of
-all the supported bitstream filters included in your build.
-
-Below is a description of the currently available bitstream filters.

-
-Convert MJPEG/AVI1 packets to full JPEG/JFIF packets.
-
-MJPEG is a video codec wherein each video frame is essentially a
-JPEG image. The individual frames can be extracted without loss,
-e.g. by
-
-@example
-ffmpeg -i ../some_mjpeg.avi -vcodec copy frames_%d.jpg
-@end example
-
-Unfortunately, these chunks are incomplete JPEG images, because
-they lack the DHT segment required for decoding. Quoting from
-@url{http://www.digitalpreservation.gov/formats/fdd/fdd000063.shtml}:
-
-Avery Lee, writing in the rec.video.desktop newsgroup in 2001,
-commented that "MJPEG, or at least the MJPEG in AVIs having the
-MJPG fourcc, is restricted JPEG with a fixed -- and *omitted* --
-Huffman table. The JPEG must be YCbCr colorspace, it must be 4:2:2,
-and it must use basic Huffman encoding, not arithmetic or
-progressive. . . . You can indeed extract the MJPEG frames and
-decode them with a regular JPEG decoder, but you have to prepend
-the DHT segment to them, or else the decoder won't have any idea
-how to decompress the data. The exact table necessary is given in
-the OpenDML spec."
-
-This bitstream filter patches the header of frames extracted from an MJPEG
-stream (carrying the AVI1 header ID and lacking a DHT segment) to
-produce fully qualified JPEG images.
-
-@example
-ffmpeg -i mjpeg-movie.avi -vcodec copy -vbsf mjpeg2jpeg frame_%d.jpg
-exiftran -i -9 frame*.jpg
-ffmpeg -i frame_%d.jpg -vcodec copy rotated.avi

-    Default target, builds all the libraries and the executables.
-
-fate
-    Run the fate test suite, note you must have installed it

-
-install
-    Install headers, libraries and programs.
-
-libavformat/output-example
-    Build the libavformat basic example.
-
-libavcodec/api-example
-    Build the libavcodec basic example.
-
-libswscale/swscale-test
-    Build the swscale self-test (useful also as example).
-
-
-Useful standard make commands:
-make -t <target>
-    Touch all files that otherwise would be build, this is useful to reduce
-    unneeded rebuilding when changing headers, but note you must force rebuilds
-    of files that actually need it by hand then.
-
-make -j<num>
-    rebuild with multiple jobs at the same time. Faster on multi processor systems
-
-make -k
-    continue build in case of errors, this is useful for the regression tests
-    sometimes but note it will still not run all reg tests.

-@chapter Demuxers
-@c man begin DEMUXERS
-
-Demuxers are configured elements in FFmpeg which allow to read the
-multimedia streams from a particular type of file.
-
-When you configure your FFmpeg build, all the supported demuxers
-are enabled by default. You can list all available ones using the
-configure option "--list-demuxers".
-
-You can disable all the demuxers using the configure option
-"--disable-demuxers", and selectively enable a single demuxer with
-the option "--enable-demuxer=@var{DEMUXER}", or disable it
-with the option "--disable-demuxer=@var{DEMUXER}".
-
-The option "-formats" of the ff* tools will display the list of
-enabled demuxers.
-
-The description of some of the currently available demuxers follows.
-
-@section image2
-
-Image file demuxer.
-
-This demuxer reads from a list of image files specified by a pattern.
-
-The pattern may contain the string "%d" or "%0@var{N}d", which
-specifies the position of the characters representing a sequential
-number in each filename matched by the pattern. If the form
-"%d0@var{N}d" is used, the string representing the number in each
-filename is 0-padded and @var{N} is the total number of 0-padded
-digits representing the number. The literal character '%' can be
-specified in the pattern with the string "%%".
-
-If the pattern contains "%d" or "%0@var{N}d", the first filename of
-the file list specified by the pattern must contain a number
-inclusively contained between 0 and 4, all the following numbers must
-be sequential. This limitation may be hopefully fixed.
-
-The pattern may contain a suffix which is used to automatically
-determine the format of the images contained in the files.
-
-For example the pattern "img-%03d.bmp" will match a sequence of
-filenames of the form @file{img-001.bmp}, @file{img-002.bmp}, ...,
-@file{img-010.bmp}, etc.; the pattern "i%%m%%g-%d.jpg" will match a
-sequence of filenames of the form @file{i%m%g-1.jpg},
-@file{i%m%g-2.jpg}, ..., @file{i%m%g-10.jpg}, etc.
-
-The size, the pixel format, and the format of each image must be the
-same for all the files in the sequence.
-
-The following example shows how to use @file{ffmpeg} for creating a
-video from the images in the file sequence @file{img-001.jpeg},
-@file{img-002.jpeg}, ..., assuming an input framerate of 10 frames per
-second:
-@example
-ffmpeg -r 10 -f image2 -i 'img-%03d.jpeg' out.avi
-@end example
-
-Note that the pattern must not necessarily contain "%d" or
-"%0@var{N}d", for example to convert a single image file
-@file{img.jpeg} you can employ the command:
-@example
-ffmpeg -f image2 -i img.jpeg img.png
-@end example
-
-@section applehttp
-
-Apple HTTP Live Streaming demuxer.
-
-This demuxer presents all AVStreams from all variant streams.
-The id field is set to the bitrate variant index number. By setting
-the discard flags on AVStreams (by pressing 'a' or 'v' in ffplay),
-the caller can decide which variant streams to actually receive.
-The total bitrate of the variant that the stream belongs to is
-available in a metadata key named "variant_bitrate".

-@section API
-@itemize @bullet
-@item libavcodec is the library containing the codecs (both encoding and
-decoding). Look at @file{libavcodec/apiexample.c} to see how to use it.
-
-@item libavformat is the library containing the file format handling (mux and
-demux code for several formats). Look at @file{ffplay.c} to use it in a
-player. See @file{libavformat/output-example.c} to use it to generate
-audio or video streams.
-
-@end itemize
-
-@section Integrating libavcodec or libavformat in your program
-
-You can integrate all the source code of the libraries to link them
-statically to avoid any version problem. All you need is to provide a
-'config.mak' and a 'config.h' in the parent directory. See the defines
-generated by ./configure to understand what is needed.
-
-You can use libavcodec or libavformat in your commercial program, but
-@emph{any patch you make must be published}. The best way to proceed is
-to send your patches to the FFmpeg mailing list.

-
-@anchor{Coding Rules}
-@section Coding Rules
-
-FFmpeg is programmed in the ISO C90 language with a few additional
-features from ISO C99, namely:
-@itemize @bullet
-@item
-the @samp{inline} keyword;
-@item
-@samp{//} comments;
-@item
-designated struct initializers (@samp{struct s x = @{ .i = 17 @};})
-@item
-compound literals (@samp{x = (struct s) @{ 17, 23 @};})
-@end itemize
-
-These features are supported by all compilers we care about, so we will not
-accept patches to remove their use unless they absolutely do not impair
-clarity and performance.
-
-All code must compile with recent versions of GCC and a number of other
-currently supported compilers. To ensure compatibility, please do not use
-additional C99 features or GCC extensions. Especially watch out for:
-@itemize @bullet
-@item
-mixing statements and declarations;
-@item
-@samp{long long} (use @samp{int64_t} instead);
-@item
-@samp{__attribute__} not protected by @samp{#ifdef __GNUC__} or similar;
-@item
-GCC statement expressions (@samp{(x = (@{ int y = 4; y; @})}).
-@end itemize
-
-Indent size is 4.
-The presentation is one inspired by 'indent -i4 -kr -nut'.
-The TAB character is forbidden outside of Makefiles as is any
-form of trailing whitespace. Commits containing either will be
-rejected by the git repository.
-
-The main priority in FFmpeg is simplicity and small code size in order to
-minimize the bug count.
-
-Comments: Use the JavaDoc/Doxygen
-format (see examples below) so that code documentation
-can be generated automatically. All nontrivial functions should have a comment
-above them explaining what the function does, even if it is just one sentence.
-All structures and their member variables should be documented, too.
-@example
-/**
- * @@file
- * MPEG codec.
- * @@author ...
- */
-
-/**
- * Summary sentence.
- * more text ...
- * ...
- */
-typedef struct Foobar@{
-    int var1; /**< var1 description */
-    int var2; ///< var2 description
-    /** var3 description */
-    int var3;

- * Summary sentence.
- * more text ...
- * ...
- * @@param my_parameter description of my_parameter
- * @@return return value description
- */
-int myfunc(int my_parameter)
-...
-@end example
-
-fprintf and printf are forbidden in libavformat and libavcodec,
-please use av_log() instead.
-
-Casts should be used only when necessary. Unneeded parentheses
-should also be avoided if they don't make the code easier to understand.
-
-@section Development Policy
-
-@enumerate
-@item
-   Contributions should be licensed under the LGPL 2.1, including an
-   "or any later version" clause, or the MIT license.  GPL 2 including
-   an "or any later version" clause is also acceptable, but LGPL is
-   preferred.
-@item
-   You must not commit code which breaks FFmpeg! (Meaning unfinished but
-   enabled code which breaks compilation or compiles but does not work or
-   breaks the regression tests)
-   You can commit unfinished stuff (for testing etc), but it must be disabled
-   (#ifdef etc) by default so it does not interfere with other developers'
-   work.
-@item
-   You do not have to over-test things. If it works for you, and you think it
-   should work for others, then commit. If your code has problems
-   (portability, triggers compiler bugs, unusual environment etc) they will be
-   reported and eventually fixed.
-@item
-   Do not commit unrelated changes together, split them into self-contained
-   pieces. Also do not forget that if part B depends on part A, but A does not
-   depend on B, then A can and should be committed first and separate from B.
-   Keeping changes well split into self-contained parts makes reviewing and
-   understanding them on the commit log mailing list easier. This also helps
-   in case of debugging later on.
-   Also if you have doubts about splitting or not splitting, do not hesitate to
-   ask/discuss it on the developer mailing list.
-@item
-   Do not change behavior of the programs (renaming options etc) or public
-   API or ABI without first discussing it on the ffmpeg-devel mailing list.
-   Do not remove functionality from the code. Just improve!
-
-   Note: Redundant code can be removed.
-@item
-   Do not commit changes to the build system (Makefiles, configure script)
-   which change behavior, defaults etc, without asking first. The same
-   applies to compiler warning fixes, trivial looking fixes and to code
-   maintained by other developers. We usually have a reason for doing things
-   the way we do. Send your changes as patches to the ffmpeg-devel mailing
-   list, and if the code maintainers say OK, you may commit. This does not
-   apply to files you wrote and/or maintain.
-@item
-   We refuse source indentation and other cosmetic changes if they are mixed
-   with functional changes, such commits will be rejected and removed. Every
-   developer has his own indentation style, you should not change it. Of course
-   if you (re)write something, you can use your own style, even though we would
-   prefer if the indentation throughout FFmpeg was consistent (Many projects
-   force a given indentation style - we do not.). If you really need to make
-   indentation changes (try to avoid this), separate them strictly from real
-   changes.
-
-   NOTE: If you had to put if()@{ .. @} over a large (> 5 lines) chunk of code,
-   then either do NOT change the indentation of the inner part within (do not
-   move it to the right)! or do so in a separate commit
-@item
-   Always fill out the commit log message. Describe in a few lines what you
-   changed and why. You can refer to mailing list postings if you fix a
-   particular bug. Comments such as "fixed!" or "Changed it." are unacceptable.
-   Recommanded format:
-   area changed: Short 1 line description
-
-   details describing what and why and giving references.
-@item
-   Make sure the author of the commit is set correctly. (see git commit --author)
-   If you apply a patch, send an
-   answer to ffmpeg-devel (or wherever you got the patch from) saying that
-   you applied the patch.
-@item
-   When applying patches that have been discussed (at length) on the mailing
-   list, reference the thread in the log message.
-@item
-    Do NOT commit to code actively maintained by others without permission.
-    Send a patch to ffmpeg-devel instead. If no one answers within a reasonable
-    timeframe (12h for build failures and security fixes, 3 days small changes,
-    1 week for big patches) then commit your patch if you think it is OK.
-    Also note, the maintainer can simply ask for more time to review!
-@item
-    Subscribe to the ffmpeg-cvslog mailing list. The diffs of all commits
-    are sent there and reviewed by all the other developers. Bugs and possible
-    improvements or general questions regarding commits are discussed there. We
-    expect you to react if problems with your code are uncovered.
-@item
-    Update the documentation if you change behavior or add features. If you are
-    unsure how best to do this, send a patch to ffmpeg-devel, the documentation
-    maintainer(s) will review and commit your stuff.
-@item
-    Try to keep important discussions and requests (also) on the public
-    developer mailing list, so that all developers can benefit from them.
-@item
-    Never write to unallocated memory, never write over the end of arrays,
-    always check values read from some untrusted source before using them
-    as array index or other risky things.
-@item
-    Remember to check if you need to bump versions for the specific libav
-    parts (libavutil, libavcodec, libavformat) you are changing. You need
-    to change the version integer.
-    Incrementing the first component means no backward compatibility to
-    previous versions (e.g. removal of a function from the public API).
-    Incrementing the second component means backward compatible change
-    (e.g. addition of a function to the public API or extension of an
-    existing data structure).
-    Incrementing the third component means a noteworthy binary compatible
-    change (e.g. encoder bug fix that matters for the decoder).
-@item
-    Compiler warnings indicate potential bugs or code with bad style. If a type of
-    warning always points to correct and clean code, that warning should
-    be disabled, not the code changed.
-    Thus the remaining warnings can either be bugs or correct code.
-    If it is a bug, the bug has to be fixed. If it is not, the code should
-    be changed to not generate a warning unless that causes a slowdown
-    or obfuscates the code.
-@item
-    If you add a new file, give it a proper license header. Do not copy and
-    paste it from a random place, use an existing file as template.
-@end enumerate
-
-We think our rules are not too hard. If you have comments, contact us.
-
-Note, these rules are mostly borrowed from the MPlayer project.
-
-@section Submitting patches
-
-First, read the @ref{Coding Rules} above if you did not yet, in particular
-the rules regarding patch submission.
-
-When you submit your patch, please use @code{git format-patch} or
-@code{git send-email}. We cannot read other diffs :-)
-
-Also please do not submit a patch which contains several unrelated changes.
-Split it into separate, self-contained pieces. This does not mean splitting
-file by file. Instead, make the patch as small as possible while still
-keeping it as a logical unit that contains an individual change, even
-if it spans multiple files. This makes reviewing your patches much easier
-for us and greatly increases your chances of getting your patch applied.
-
-Use the patcheck tool of FFmpeg to check your patch.
-The tool is located in the tools directory.
-
-Run the @ref{Regression Tests} before submitting a patch in order to verify
-it does not cause unexpected problems.
-
-Patches should be posted as base64 encoded attachments (or any other
-encoding which ensures that the patch will not be trashed during
-transmission) to the ffmpeg-devel mailing list, see
-@url{http://lists.ffmpeg.org/mailman/listinfo/ffmpeg-devel}
-
-It also helps quite a bit if you tell us what the patch does (for example
-'replaces lrint by lrintf'), and why (for example '*BSD isn't C99 compliant
-and has no lrint()')
-
-Also please if you send several patches, send each patch as a separate mail,
-do not attach several unrelated patches to the same mail.
-
-Your patch will be reviewed on the mailing list. You will likely be asked
-to make some changes and are expected to send in an improved version that
-incorporates the requests from the review. This process may go through
-several iterations. Once your patch is deemed good enough, some developer
-will pick it up and commit it to the official FFmpeg tree.
-
-Give us a few days to react. But if some time passes without reaction,
-send a reminder by email. Your patch should eventually be dealt with.

-@section Patch review process
-
-All patches posted to ffmpeg-devel will be reviewed, unless they contain a
-clear note that the patch is not for the git master branch.
-Reviews and comments will be posted as replies to the patch on the
-mailing list. The patch submitter then has to take care of every comment,
-that can be by resubmitting a changed patch or by discussion. Resubmitted
-patches will themselves be reviewed like any other patch. If at some point
-a patch passes review with no comments then it is approved, that can for
-simple and small patches happen immediately while large patches will generally
-have to be changed and reviewed many times before they are approved.
-After a patch is approved it will be committed to the repository.
-
-We will review all submitted patches, but sometimes we are quite busy so
-especially for large patches this can take several weeks.
-
-When resubmitting patches, please do not make any significant changes
-not related to the comments received during review. Such patches will
-be rejected. Instead, submit  significant changes or new features as
-separate patches.
-
-@section Regression tests
-
-Before submitting a patch (or committing to the repository), you should at least
-test that you did not break anything.
-
-The regression tests build a synthetic video stream and a synthetic
-audio stream. These are then encoded and decoded with all codecs or
-formats. The CRC (or MD5) of each generated file is recorded in a
-result file. A 'diff' is launched to compare the reference results and
-the result file. The output is checked immediately after each test
-has run.
-
-The regression tests then go on to test the FFserver code with a
-limited set of streams. It is important that this step runs correctly
-as well.
-
-Run 'make test' to test all the codecs and formats. Commands like
-'make regtest-mpeg2' can be used to run a single test. By default,
-make will abort if any test fails. To run all tests regardless,
-use make -k. To get a more verbose output, use 'make V=1 test' or
-'make V=2 test'.
-
-Run 'make fulltest' to test all the codecs, formats and FFserver.
-
-[Of course, some patches may change the results of the regression tests. In
-this case, the reference results of the regression tests shall be modified
-accordingly].

-The AC-3 metadata options are used to set parameters that describe the audio,
-but in most cases do not affect the audio encoding itself. Some of the options
-do directly affect or influence the decoding and playback of the resulting
-bitstream, while others are just for informational purposes. A few of the
-options will add bits to the output stream that could otherwise be used for
-audio data, and will thus affect the quality of the output. Those will be
-indicated accordingly with a note in the option list below.
-
-These parameters are described in detail in several publicly-available
-documents.

-@subsubsection Downmix Levels
-
-@table @option
-
-@item -center_mixlev @var{level}
-Center Mix Level. The amount of gain the decoder should apply to the center
-channel when downmixing to stereo. This field will only be written to the
-bitstream if a center channel is present. The value is specified as a scale
-factor. There are 3 valid values:

-@subsubsection Audio Production Information
-Audio Production Information is optional information describing the mixing
-environment.  Either none or both of the fields are written to the bitstream.
-
-@table @option
-
-@item -mixing_level @var{number}
-Mixing Level. Specifies peak sound pressure level (SPL) in the production
-environment when the mix was mastered. Valid values are 80 to 111, or -1 for
-unknown or not indicated. The default value is -1, but that value cannot be
-used if the Audio Production Information is written to the bitstream. Therefore,
-if the @code{room_type} option is not the default value, the @code{mixing_level}
-option must not be -1.
-
-@item -room_type @var{type}
-Room Type. Describes the equalization used during the final mixing session at
-the studio or on the dubbing stage. A large room is a dubbing stage with the
-industry standard X-curve equalization; a small room has flat equalization.
-This field will not be written to the bitstream if both the @code{mixing_level}
-option and the @code{room_type} option have the default values.

-Copyright Exists
-@end table
-
-@item -dialnorm @var{value}
-Dialogue Normalization. Indicates how far the average dialogue level of the
-program is below digital 100% full scale (0 dBFS). This parameter determines a
-level shift during audio reproduction that sets the average volume of the
-dialogue to a preset level. The goal is to match volume level between program
-sources. A value of -31dB will result in no volume level change, relative to
-the source volume, during audio reproduction. Valid values are whole numbers in
-the range -31 to -1, with -31 being the default.
-
-@item -dsur_mode @var{mode}
-Dolby Surround Mode. Specifies whether the stereo signal uses Dolby Surround
-(Pro Logic). This field will only be written to the bitstream if the audio
-stream is stereo. Using this option does @b{NOT} mean the encoder will actually
-apply Dolby Surround processing.
-@table @option

-@subsection Extended Bitstream Information
-The extended bitstream options are part of the Alternate Bit Stream Syntax as
-specified in Annex D of the A/52:2010 standard. It is grouped into 2 parts.
-If any one parameter in a group is specified, all values in that group will be
-written to the bitstream.  Default values are used for those that are written
-but have not been specified.  If the mixing levels are written, the decoder
-will use these values instead of the ones specified in the @code{center_mixlev}
-and @code{surround_mixlev} options if it supports the Alternate Bit Stream
-Syntax.

-is highly recommended that it be left as enabled except for testing purposes.
-

-
-@subsection Floating-Point-Only AC-3 Encoding Options
-
-These options are only valid for the floating-point encoder and do not exist

-
-@table @option
-
-@item -channel_coupling @var{boolean}
-Enables/Disables use of channel coupling, which is an optional AC-3 feature
-that increases quality by combining high frequency information from multiple
-channels into a single channel. The per-channel high frequency information is
-sent with less accuracy in both the frequency and time domains. This allows
-more bits to be used for lower frequencies while preserving enough information
-to reconstruct the high frequencies. This option is enabled by default for the
-floating-point encoder and should generally be left as enabled except for
-testing purposes or to increase encoding speed.

-@chapter Expression Evaluation
-@c man begin EXPRESSION EVALUATION
-
-When evaluating an arithemetic expression, FFmpeg uses an internal
-formula evaluator, implemented through the @file{libavutil/eval.h}
-interface.
-
-An expression may contain unary, binary operators, constants, and
-functions.
-
-Two expressions @var{expr1} and @var{expr2} can be combined to form
-another expression "@var{expr1};@var{expr2}".
-@var{expr1} and @var{expr2} are evaluated in turn, and the new
-expression evaluates to the value of @var{expr2}.
-
-The following binary operators are available: @code{+}, @code{-},
-@code{*}, @code{/}, @code{^}.
-
-The following unary operators are available: @code{+}, @code{-}.
-
-The following functions are available:
-@table @option
-@item sinh(x)
-@item cosh(x)
-@item tanh(x)
-@item sin(x)
-@item cos(x)
-@item tan(x)

-@item acos(x)
-@item exp(x)
-@item log(x)
-@item abs(x)
-@item squish(x)
-@item gauss(x)
-@item isnan(x)
-Return 1.0 if @var{x} is NAN, 0.0 otherwise.
-
-@item mod(x, y)
-@item max(x, y)
-@item min(x, y)
-@item eq(x, y)
-@item gte(x, y)
-@item gt(x, y)
-@item lte(x, y)
-@item lt(x, y)
-@item st(var, expr)
-Allow to store the value of the expression @var{expr} in an internal
-variable. @var{var} specifies the number of the variable where to
-store the value, and it is a value ranging from 0 to 9. The function
-returns the value stored in the internal variable.
-
-@item ld(var)
-Allow to load the value of the internal variable with number
-@var{var}, which was previosly stored with st(@var{var}, @var{expr}).
-The function returns the loaded value.
-
-@item while(cond, expr)
-Evaluate expression @var{expr} while the expression @var{cond} is
-non-zero, and returns the value of the last @var{expr} evaluation, or
-NAN if @var{cond} was always false.
-
-@item ceil(expr)
-Round the value of expression @var{expr} upwards to the nearest
-integer. For example, "ceil(1.5)" is "2.0".
-
-@item floor(expr)
-Round the value of expression @var{expr} downwards to the nearest
-integer. For example, "floor(-1.5)" is "-2.0".
-
-@item trunc(expr)
-Round the value of expression @var{expr} towards zero to the nearest
-integer. For example, "trunc(-1.5)" is "-1.0".
-
-@item sqrt(expr)
-Compute the square root of @var{expr}. This is equivalent to
-"(@var{expr})^.5".
-
-@item not(expr)
-Return 1.0 if @var{expr} is zero, 0.0 otherwise.
-
-@item pow(x, y)
-Compute the power of @var{x} elevated @var{y}, it is equivalent to
-"(@var{x})^(@var{y})".
-@end table
-
-Note that:
-
-@code{*} works like AND
-
-@code{+} works like OR
-
-thus
-@example
-if A then B else C
-@end example
-is equivalent to
-@example
-A*B + not(A)*C
-@end example
-
-In your C code, you can extend the list of unary and binary functions,
-and define recognized constants, so that they are available for your
-expressions.
-
-The evaluator also recognizes the International System number
-postfixes. If 'i' is appended after the postfix, powers of 2 are used
-instead of powers of 10. The 'B' postfix multiplies the value for 8,
-and can be appended after another postfix or used alone. This allows
-using for example 'KB', 'MiB', 'G' and 'B' as postfix.
-
-Follows the list of available International System postfixes, with
-indication of the corresponding powers of 10 and of 2.

-@chapter General Questions
-
-@section When will the next FFmpeg version be released? / Why are FFmpeg releases so few and far between?
-
-Like most open source projects FFmpeg suffers from a certain lack of
-manpower. For this reason the developers have to prioritize the work
-they do and putting out releases is not at the top of the list, fixing
-bugs and reviewing patches takes precedence. Please don't complain or
-request more timely and/or frequent releases unless you are willing to
-help out creating them.
-
-@section I have a problem with an old version of FFmpeg; where should I report it?
-Nowhere. We do not support old FFmpeg versions in any way, we simply lack
-the time, motivation and manpower to do so. If you have a problem with an
-old version of FFmpeg, upgrade to the latest git snapshot. If you
-still experience the problem, then you can report it according to the
-guidelines in @url{http://ffmpeg.org/bugreports.html}.
-
-@section Why doesn't FFmpeg support feature [xyz]?
-
-Because no one has taken on that task yet. FFmpeg development is
-driven by the tasks that are important to the individual developers.
-If there is a feature that is important to you, the best way to get
-it implemented is to undertake the task yourself or sponsor a developer.
-
-@section FFmpeg does not support codec XXX. Can you include a Windows DLL loader to support it?
-
-No. Windows DLLs are not portable, bloated and often slow.
-Moreover FFmpeg strives to support all codecs natively.
-A DLL loader is not conducive to that goal.
-
-@section My bug report/mail to ffmpeg-devel/user has not received any replies.
-
-Likely reasons
-@itemize
-@item We are busy and haven't had time yet to read your report or
-investigate the issue.
-@item You didn't follow @url{http://ffmpeg.org/bugreports.html}.
-@item You didn't use git master.
-@item You reported a segmentation fault without gdb output.
-@item You describe a problem but not how to reproduce it.
-@item It's unclear if you use ffmpeg as command line tool or use
-libav* from another application.
-@item You speak about a video having problems on playback but
-not what you use to play it.
-@item We have no faint clue what you are talking about besides
-that it is related to FFmpeg.
-@end itemize
-
-@section Is there a forum for FFmpeg? I do not like mailing lists.
-
-You may view our mailing lists with a more forum-alike look here:
-@url{http://dir.gmane.org/gmane.comp.video.ffmpeg.user},
-but, if you post, please remember that our mailing list rules still apply there.
-
-@section I cannot read this file although this format seems to be supported by ffmpeg.
-
-Even if ffmpeg can read the container format, it may not support all its
-codecs. Please consult the supported codec list in the ffmpeg
-documentation.
-
-@section Which codecs are supported by Windows?
-
-Windows does not support standard formats like MPEG very well, unless you
-install some additional codecs.
-
-The following list of video codecs should work on most Windows systems:
-@table @option
-@item msmpeg4v2
-.avi/.asf
-@item msmpeg4
-.asf only
-@item wmv1
-.asf only
-@item wmv2
-.asf only
-@item mpeg4
-Only if you have some MPEG-4 codec like ffdshow or Xvid installed.
-@item mpeg1video
-.mpg only
-@end table
-Note, ASF files often have .wmv or .wma extensions in Windows. It should also
-be mentioned that Microsoft claims a patent on the ASF format, and may sue
-or threaten users who create ASF files with non-Microsoft software. It is
-strongly advised to avoid ASF where possible.
-
-The following list of audio codecs should work on most Windows systems:
-@table @option
-@item adpcm_ima_wav
-@item adpcm_ms
-@item pcm_s16le
-always
-@item libmp3lame
-If some MP3 codec like LAME is installed.
-@end table
-
-
-@chapter Compilation
-
-@section @code{error: can't find a register in class 'GENERAL_REGS' while reloading 'asm'}
-
-This is a bug in gcc. Do not report it to us. Instead, please report it to
-the gcc developers. Note that we will not add workarounds for gcc bugs.
-
-Also note that (some of) the gcc developers believe this is not a bug or
-not a bug they should fix:
-@url{http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11203}.
-Then again, some of them do not know the difference between an undecidable
-problem and an NP-hard problem...
-
-@chapter Usage
-
-@section ffmpeg does not work; what is wrong?
-
-Try a @code{make distclean} in the ffmpeg source directory before the build.
-If this does not help see
-(@url{http://ffmpeg.org/bugreports.html}).
-
-@section How do I encode single pictures into movies?
-
-First, rename your pictures to follow a numerical sequence.
-For example, img1.jpg, img2.jpg, img3.jpg,...
-Then you may run:
-
-@example
-  ffmpeg -f image2 -i img%d.jpg /tmp/a.mpg
-@end example
-
-Notice that @samp{%d} is replaced by the image number.
-
-@file{img%03d.jpg} means the sequence @file{img001.jpg}, @file{img002.jpg}, etc...
-
-If you have large number of pictures to rename, you can use the
-following command to ease the burden. The command, using the bourne
-shell syntax, symbolically links all files in the current directory
-that match @code{*jpg} to the @file{/tmp} directory in the sequence of
-@file{img001.jpg}, @file{img002.jpg} and so on.
-
-@example
-  x=1; for i in *jpg; do counter=$(printf %03d $x); ln -s "$i" /tmp/img"$counter".jpg; x=$(($x+1)); done
-@end example
-
-If you want to sequence them by oldest modified first, substitute
-@code{$(ls -r -t *jpg)} in place of @code{*jpg}.
-
-Then run:
-
-@example
-  ffmpeg -f image2 -i /tmp/img%03d.jpg /tmp/a.mpg
-@end example
-
-The same logic is used for any image format that ffmpeg reads.
-
-@section How do I encode movie to single pictures?
-
-Use:
-
-@example
-  ffmpeg -i movie.mpg movie%d.jpg
-@end example
-
-The @file{movie.mpg} used as input will be converted to
-@file{movie1.jpg}, @file{movie2.jpg}, etc...
-
-Instead of relying on file format self-recognition, you may also use
-@table @option
-@item -vcodec ppm
-@item -vcodec png
-@item -vcodec mjpeg
-@end table
-to force the encoding.
-
-Applying that to the previous example:
-@example
-  ffmpeg -i movie.mpg -f image2 -vcodec mjpeg menu%d.jpg
-@end example
-
-Beware that there is no "jpeg" codec. Use "mjpeg" instead.
-
-@section Why do I see a slight quality degradation with multithreaded MPEG* encoding?
-
-For multithreaded MPEG* encoding, the encoded slices must be independent,
-otherwise thread n would practically have to wait for n-1 to finish, so it's
-quite logical that there is a small reduction of quality. This is not a bug.
-
-@section How can I read from the standard input or write to the standard output?
-
-Use @file{-} as file name.
-
-@section -f jpeg doesn't work.
-
-Try '-f image2 test%d.jpg'.
-
-@section Why can I not change the framerate?
-
-Some codecs, like MPEG-1/2, only allow a small number of fixed framerates.
-Choose a different codec with the -vcodec command line option.
-
-@section How do I encode Xvid or DivX video with ffmpeg?
-
-Both Xvid and DivX (version 4+) are implementations of the ISO MPEG-4
-standard (note that there are many other coding formats that use this
-same standard). Thus, use '-vcodec mpeg4' to encode in these formats. The
-default fourcc stored in an MPEG-4-coded file will be 'FMP4'. If you want
-a different fourcc, use the '-vtag' option. E.g., '-vtag xvid' will
-force the fourcc 'xvid' to be stored as the video fourcc rather than the
-default.

-@section Which are good parameters for encoding high quality MPEG-4?
-
-'-mbd rd -flags +mv4+aic -trellis 2 -cmp 2 -subcmp 2 -g 300 -pass 1/2',
-things to try: '-bf 2', '-flags qprd', '-flags mv0', '-flags skiprd'.
-
-@section Which are good parameters for encoding high quality MPEG-1/MPEG-2?
-
-'-mbd rd -trellis 2 -cmp 2 -subcmp 2 -g 100 -pass 1/2'
-but beware the '-g 100' might cause problems with some decoders.
-Things to try: '-bf 2', '-flags qprd', '-flags mv0', '-flags skiprd.
-
-@section Interlaced video looks very bad when encoded with ffmpeg, what is wrong?
-
-You should use '-flags +ilme+ildct' and maybe '-flags +alt' for interlaced
-material, and try '-top 0/1' if the result looks really messed-up.
-
-@section How can I read DirectShow files?
-
-If you have built FFmpeg with @code{./configure --enable-avisynth}
-(only possible on MinGW/Cygwin platforms),
-then you may use any file that DirectShow can read as input.
-
-Just create an "input.avs" text file with this single line ...
-@example
-  DirectShowSource("C:\path to your file\yourfile.asf")
-@end example
-... and then feed that text file to ffmpeg:
-@example
-  ffmpeg -i input.avs
-@end example
-
-For ANY other help on Avisynth, please visit the
-@uref{http://www.avisynth.org/, Avisynth homepage}.
-
-@section How can I join video files?
-
-A few multimedia containers (MPEG-1, MPEG-2 PS, DV) allow to join video files by
-merely concatenating them.
-
-Hence you may concatenate your multimedia files by first transcoding them to
-these privileged formats, then using the humble @code{cat} command (or the
-equally humble @code{copy} under Windows), and finally transcoding back to your
-format of choice.
-
-@example
-ffmpeg -i input1.avi -sameq intermediate1.mpg
-ffmpeg -i input2.avi -sameq intermediate2.mpg
-cat intermediate1.mpg intermediate2.mpg > intermediate_all.mpg
-ffmpeg -i intermediate_all.mpg -sameq output.avi
-@end example
-
-Notice that you should either use @code{-sameq} or set a reasonably high
-bitrate for your intermediate and output files, if you want to preserve
-video quality.
-
-Also notice that you may avoid the huge intermediate files by taking advantage
-of named pipes, should your platform support it:
-
-@example
-mkfifo intermediate1.mpg
-mkfifo intermediate2.mpg
-ffmpeg -i input1.avi -sameq -y intermediate1.mpg < /dev/null &
-ffmpeg -i input2.avi -sameq -y intermediate2.mpg < /dev/null &
-cat intermediate1.mpg intermediate2.mpg |\
-ffmpeg -f mpeg -i - -sameq -vcodec mpeg4 -acodec libmp3lame output.avi
-@end example
-
-Similarly, the yuv4mpegpipe format, and the raw video, raw audio codecs also
-allow concatenation, and the transcoding step is almost lossless.
-When using multiple yuv4mpegpipe(s), the first line needs to be discarded
-from all but the first stream. This can be accomplished by piping through
-@code{tail} as seen below. Note that when piping through @code{tail} you
-must use command grouping, @code{@{  ;@}}, to background properly.
-
-For example, let's say we want to join two FLV files into an output.flv file:
-
-@example
-mkfifo temp1.a
-mkfifo temp1.v
-mkfifo temp2.a
-mkfifo temp2.v
-mkfifo all.a
-mkfifo all.v
-ffmpeg -i input1.flv -vn -f u16le -acodec pcm_s16le -ac 2 -ar 44100 - > temp1.a < /dev/null &
-ffmpeg -i input2.flv -vn -f u16le -acodec pcm_s16le -ac 2 -ar 44100 - > temp2.a < /dev/null &
-ffmpeg -i input1.flv -an -f yuv4mpegpipe - > temp1.v < /dev/null &
-@{ ffmpeg -i input2.flv -an -f yuv4mpegpipe - < /dev/null | tail -n +2 > temp2.v ; @} &
-cat temp1.a temp2.a > all.a &
-cat temp1.v temp2.v > all.v &
-ffmpeg -f u16le -acodec pcm_s16le -ac 2 -ar 44100 -i all.a \
-       -f yuv4mpegpipe -i all.v \
-       -sameq -y output.flv
-rm temp[12].[av] all.[av]
-@end example
-
-@section The ffmpeg program does not respect the -maxrate setting, some frames are bigger than maxrate/fps.
-
-Read the MPEG spec about video buffer verifier.
-
-@section I want CBR, but no matter what I do frame sizes differ.
-
-You do not understand what CBR is, please read the MPEG spec.
-Read about video buffer verifier and constant bitrate.
-The one sentence summary is that there is a buffer and the input rate is
-constant, the output can vary as needed.
-
-@section How do I check if a stream is CBR?
-
-To quote the MPEG-2 spec:
-"There is no way to tell that a bitstream is constant bitrate without
-examining all of the vbv_delay values and making complicated computations."
-
-
-@chapter Development
-
-@section Are there examples illustrating how to use the FFmpeg libraries, particularly libavcodec and libavformat?
-
-Yes. Read the Developers Guide of the FFmpeg documentation. Alternatively,
-examine the source code for one of the many open source projects that
-already incorporate FFmpeg at (@url{projects.html}).
-
-@section Can you support my C compiler XXX?
-
-It depends. If your compiler is C99-compliant, then patches to support
-it are likely to be welcome if they do not pollute the source code
-with @code{#ifdef}s related to the compiler.
-
-@section Is Microsoft Visual C++ supported?
-
-No. Microsoft Visual C++ is not compliant to the C99 standard and does
-not - among other things - support the inline assembly used in FFmpeg.
-If you wish to use MSVC++ for your
-project then you can link the MSVC++ code with libav* as long as
-you compile the latter with a working C compiler. For more information, see
-the @emph{Microsoft Visual C++ compatibility} section in the FFmpeg
-documentation.
-
-There have been efforts to make FFmpeg compatible with MSVC++ in the
-past. However, they have all been rejected as too intrusive, especially
-since MinGW does the job adequately. None of the core developers
-work with MSVC++ and thus this item is low priority. Should you find
-the silver bullet that solves this problem, feel free to shoot it at us.
-
-We strongly recommend you to move over from MSVC++ to MinGW tools.
-
-@section Can I use FFmpeg or libavcodec under Windows?
-
-Yes, but the Cygwin or MinGW tools @emph{must} be used to compile FFmpeg.
-Read the @emph{Windows} section in the FFmpeg documentation to find more
-information.
-
-To get help and instructions for building FFmpeg under Windows, check out
-the FFmpeg Windows Help Forum at
-@url{http://ffmpeg.arrozcru.org/}.
-
-@section Can you add automake, libtool or autoconf support?
-
-No. These tools are too bloated and they complicate the build.
-
-@section Why not rewrite ffmpeg in object-oriented C++?
-
-FFmpeg is already organized in a highly modular manner and does not need to
-be rewritten in a formal object language. Further, many of the developers
-favor straight C; it works for them. For more arguments on this matter,
-read @uref{http://www.tux.org/lkml/#s15, "Programming Religion"}.
-
-@section Why are the ffmpeg programs devoid of debugging symbols?
-
-The build process creates ffmpeg_g, ffplay_g, etc. which contain full debug
-information. Those binaries are stripped to create ffmpeg, ffplay, etc. If
-you need the debug information, use the *_g versions.
-
-@section I do not like the LGPL, can I contribute code under the GPL instead?
-
-Yes, as long as the code is optional and can easily and cleanly be placed
-under #if CONFIG_GPL without breaking anything. So for example a new codec
-or filter would be OK under GPL while a bug fix to LGPL code would not.
-
-@section I want to compile xyz.c alone but my compiler produced many errors.
-
-Common code is in its own files in libav* and is used by the individual
-codecs. They will not work without the common parts, you have to compile
-the whole libav*. If you wish, disable some parts with configure switches.
-You can also try to hack it and remove more, but if you had problems fixing
-the compilation failure then you are probably not qualified for this.
-
-@section I'm using libavcodec from within my C++ application but the linker complains about missing symbols which seem to be available.
-
-FFmpeg is a pure C project, so to use the libraries within your C++ application
-you need to explicitly state that you are using a C library. You can do this by
-encompassing your FFmpeg includes using @code{extern "C"}.
-
-See @url{http://www.parashift.com/c++-faq-lite/mixing-c-and-cpp.html#faq-32.3}
-
-@section I'm using libavutil from within my C++ application but the compiler complains about 'UINT64_C' was not declared in this scope
-
-Libav is a pure C project using C99 math features, in order to enable C++
-to use them you have to append -D__STDC_CONSTANT_MACROS to your CXXFLAGS
-
-@section I have a file in memory / a API different from *open/*read/ libc how do I use it with libavformat?
-
-You have to implement a URLProtocol, see @file{libavformat/file.c} in
-FFmpeg and @file{libmpdemux/demux_lavf.c} in MPlayer sources.
-
-@section I get "No compatible shell script interpreter found." in MSys.
-
-The standard MSys bash (2.04) is broken. You need to install 2.05 or later.
-
-@section I get "./configure: line <xxx>: pr: command not found" in MSys.
-
-The standard MSys install doesn't come with pr. You need to get it from the coreutils package.
-
-@section Where can I find libav* headers for Pascal/Delphi?
-
-see @url{http://www.iversenit.dk/dev/ffmpeg-headers/}
-
-@section Where is the documentation about ffv1, msmpeg4, asv1, 4xm?
-
-see @url{http://www.ffmpeg.org/~michael/}
-
-@section How do I feed H.263-RTP (and other codecs in RTP) to libavcodec?
-
-Even if peculiar since it is network oriented, RTP is a container like any
-other. You have to @emph{demux} RTP before feeding the payload to libavcodec.
-In this specific case please look at RFC 4629 to see how it should be done.
-
-@section AVStream.r_frame_rate is wrong, it is much larger than the framerate.
-
-r_frame_rate is NOT the average framerate, it is the smallest framerate
-that can accurately represent all timestamps. So no, it is not
-wrong if it is larger than the average!
-For example, if you have mixed 25 and 30 fps content, then r_frame_rate
-will be 150.

-FATE Automated Testing Environment
-
-FATE provides a regression testsuite that can be run locally or configured
-to send reports to fate.ffmpeg.org.
-In order to run, it needs a large amount of data (samples and references)
-that is provided separately from the actual source distribution.
-
-Use the following command to get the fate test samples
-
-# make fate-rsync SAMPLES=fate-suite/
-
-To inform the build system about the testsuite location, pass
-`--samples=<path to the samples>` to configure or set the SAMPLES Make
-variable or the FATE_SAMPLES environment variable to a suitable value.
-
-For information on how to set up FATE to send results to the official FFmpeg
-testing framework, please refer to the following wiki page:
-http://wiki.multimedia.cx/index.php?title=FATE
-
-FATE Makefile targets:
-
-fate-list
-    Will list all fate/regression test targets.
-
-fate
-    Run the FATE test suite (requires the fate-suite dataset).
-
-Fate Makefile variables:
-
-V
-    Verbosity level, can be set to 0, 1 or 2.
-    * 0: show just the test arguments
-    * 1: show just the command used in the test
-    * 2: show everything
-
-SAMPLES
-    Specify or override the path to the FATE samples at make time, it has a
-    meaning only while running the regression tests.
-
-THREADS
-    Specify how many threads to use while running regression tests, it is
-    quite useful to detect thread-related regressions.
-
-Example:
-    make V=1 SAMPLES=/var/fate/samples THREADS=2 fate

-
-@chapter Description
-@c man begin DESCRIPTION
-
-ffprobe gathers information from multimedia streams and prints it in
-human- and machine-readable fashion.
-
-For example it can be used to check the format of the container used
-by a multimedia stream and the format and type of each media stream
-contained in it.
-
-If a filename is specified in input, ffprobe will try to open and
-probe the file content. If the file cannot be opened or recognized as
-a multimedia file, a positive exit code is returned.
-
-ffprobe may be employed both as a standalone application or in
-combination with a textual filter, which may perform more
-sophisticated processing, e.g. statistical processing or plotting.
-
-Options are used to list some of the formats supported by ffprobe or
-for specifying which information to display, and for setting how
-ffprobe will show it.
-
-ffprobe output is designed to be easily parsable by a textual filter,
-and consists of one or more sections of the form:
-@example
-[SECTION]
-key1=val1
-...
-keyN=valN
-[/SECTION]
-@end example
-
-Metadata tags stored in the container or in the streams are recognized
-and printed in the corresponding "FORMAT" or "STREAM" section, and
-are prefixed by the string "TAG:".

-@chapter Synopsys
-
-The generic syntax is:
-
-@example
-@c man begin SYNOPSIS
-ffserver [options]
-@c man end
-@end example
-
-@chapter Description
-@c man begin DESCRIPTION
-
-ffserver is a streaming server for both audio and video. It supports
-several live feeds, streaming from files and time shifting on live feeds
-(you can seek to positions in the past on each live feed, provided you
-specify a big enough feed storage in ffserver.conf).
-
-ffserver runs in daemon mode by default; that is, it puts itself in
-the background and detaches from its TTY, unless it is launched in
-debug mode or a NoDaemon option is specified in the configuration
-file.
-
-This documentation covers only the streaming aspects of ffserver /
-ffmpeg. All questions about parameters for ffmpeg, codec questions,
-etc. are not covered here. Read @file{ffmpeg-doc.html} for more
-information.
-
-@section How does it work?
-
-ffserver receives prerecorded files or FFM streams from some ffmpeg
-instance as input, then streams them over RTP/RTSP/HTTP.
-
-An ffserver instance will listen on some port as specified in the
-configuration file. You can launch one or more instances of ffmpeg and
-send one or more FFM streams to the port where ffserver is expecting
-to receive them. Alternately, you can make ffserver launch such ffmpeg
-instances at startup.
-
-Input streams are called feeds, and each one is specified by a <Feed>
-section in the configuration file.
-
-For each feed you can have different output streams in various
-formats, each one specified by a <Stream> section in the configuration
-file.
-
-@section Status stream
-
-ffserver supports an HTTP interface which exposes the current status
-of the server.
-
-Simply point your browser to the address of the special status stream
-specified in the configuration file.
-
-For example if you have:
-@example
-<Stream status.html>
-Format status
-
-# Only allow local people to get the status
-ACL allow localhost
-ACL allow 192.168.0.0 192.168.255.255
-</Stream>
-@end example
-
-then the server will post a page with the status information when
-the special stream @file{status.html} is requested.
-
-@section What can this do?
-
-When properly configured and running, you can capture video and audio in real
-time from a suitable capture card, and stream it out over the Internet to
-either Windows Media Player or RealAudio player (with some restrictions).
-
-It can also stream from files, though that is currently broken. Very often, a
-web server can be used to serve up the files just as well.
-
-It can stream prerecorded video from .ffm files, though it is somewhat tricky
-to make it work correctly.
-
-@section What do I need?
-
-I use Linux on a 900 MHz Duron with a cheapo Bt848 based TV capture card. I'm
-using stock Linux 2.4.17 with the stock drivers. [Actually that isn't true,
-I needed some special drivers for my motherboard-based sound card.]
-
-I understand that FreeBSD systems work just fine as well.
-
-@section How do I make it work?
-
-First, build the kit. It *really* helps to have installed LAME first. Then when
-you run the ffserver ./configure, make sure that you have the
-@code{--enable-libmp3lame} flag turned on.
-
-LAME is important as it allows for streaming audio to Windows Media Player.
-Don't ask why the other audio types do not work.
-
-As a simple test, just run the following two command lines where INPUTFILE
-is some file which you can decode with ffmpeg:
-
-@example
-./ffserver -f doc/ffserver.conf &
-./ffmpeg -i INPUTFILE http://localhost:8090/feed1.ffm
-@end example
-
-At this point you should be able to go to your Windows machine and fire up
-Windows Media Player (WMP). Go to Open URL and enter
-
-@example
-    http://<linuxbox>:8090/test.asf
-@end example
-
-You should (after a short delay) see video and hear audio.
-
-WARNING: trying to stream test1.mpg doesn't work with WMP as it tries to
-transfer the entire file before starting to play.
-The same is true of AVI files.
-
-@section What happens next?
-
-You should edit the ffserver.conf file to suit your needs (in terms of
-frame rates etc). Then install ffserver and ffmpeg, write a script to start
-them up, and off you go.
-
-@section Troubleshooting
-
-@subsection I don't hear any audio, but video is fine.
-
-Maybe you didn't install LAME, or got your ./configure statement wrong. Check
-the ffmpeg output to see if a line referring to MP3 is present. If not, then
-your configuration was incorrect. If it is, then maybe your wiring is not
-set up correctly. Maybe the sound card is not getting data from the right
-input source. Maybe you have a really awful audio interface (like I do)
-that only captures in stereo and also requires that one channel be flipped.
-If you are one of these people, then export 'AUDIO_FLIP_LEFT=1' before
-starting ffmpeg.
-
-@subsection The audio and video loose sync after a while.
-
-Yes, they do.
-
-@subsection After a long while, the video update rate goes way down in WMP.
-
-Yes, it does. Who knows why?
-
-@subsection WMP 6.4 behaves differently to WMP 7.
-
-Yes, it does. Any thoughts on this would be gratefully received. These
-differences extend to embedding WMP into a web page. [There are two
-object IDs that you can use: The old one, which does not play well, and
-the new one, which does (both tested on the same system). However,
-I suspect that the new one is not available unless you have installed WMP 7].
-
-@section What else can it do?
-
-You can replay video from .ffm files that was recorded earlier.
-However, there are a number of caveats, including the fact that the
-ffserver parameters must match the original parameters used to record the
-file. If they do not, then ffserver deletes the file before recording into it.
-(Now that I write this, it seems broken).
-
-You can fiddle with many of the codec choices and encoding parameters, and
-there are a bunch more parameters that you cannot control. Post a message
-to the mailing list if there are some 'must have' parameters. Look in
-ffserver.conf for a list of the currently available controls.
-
-It will automatically generate the ASX or RAM files that are often used
-in browsers. These files are actually redirections to the underlying ASF
-or RM file. The reason for this is that the browser often fetches the
-entire file before starting up the external viewer. The redirection files
-are very small and can be transferred quickly. [The stream itself is
-often 'infinite' and thus the browser tries to download it and never
-finishes.]
-
-@section Tips
-
-* When you connect to a live stream, most players (WMP, RA, etc) want to
-buffer a certain number of seconds of material so that they can display the
-signal continuously. However, ffserver (by default) starts sending data
-in realtime. This means that there is a pause of a few seconds while the
-buffering is being done by the player. The good news is that this can be
-cured by adding a '?buffer=5' to the end of the URL. This means that the
-stream should start 5 seconds in the past -- and so the first 5 seconds
-of the stream are sent as fast as the network will allow. It will then
-slow down to real time. This noticeably improves the startup experience.
-
-You can also add a 'Preroll 15' statement into the ffserver.conf that will
-add the 15 second prebuffering on all requests that do not otherwise
-specify a time. In addition, ffserver will skip frames until a key_frame
-is found. This further reduces the startup delay by not transferring data
-that will be discarded.
-
-* You may want to adjust the MaxBandwidth in the ffserver.conf to limit
-the amount of bandwidth consumed by live streams.
-
-@section Why does the ?buffer / Preroll stop working after a time?
-
-It turns out that (on my machine at least) the number of frames successfully
-grabbed is marginally less than the number that ought to be grabbed. This
-means that the timestamp in the encoded data stream gets behind realtime.
-This means that if you say 'Preroll 10', then when the stream gets 10
-or more seconds behind, there is no Preroll left.
-
-Fixing this requires a change in the internals of how timestamps are
-handled.
-
-@section Does the @code{?date=} stuff work.
-
-Yes (subject to the limitation outlined above). Also note that whenever you
-start ffserver, it deletes the ffm file (if any parameters have changed),
-thus wiping out what you had recorded before.
-
-The format of the @code{?date=xxxxxx} is fairly flexible. You should use one
-of the following formats (the 'T' is literal):
-
-@example
-* YYYY-MM-DDTHH:MM:SS     (localtime)
-* YYYY-MM-DDTHH:MM:SSZ    (UTC)
-@end example
-
-You can omit the YYYY-MM-DD, and then it refers to the current day. However
-note that @samp{?date=16:00:00} refers to 16:00 on the current day -- this
-may be in the future and so is unlikely to be useful.
-
-You use this by adding the ?date= to the end of the URL for the stream.
-For example:   @samp{http://localhost:8080/test.asf?date=2002-07-26T23:05:00}.

-
-About Git write access:
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Before everything else, you should know how to use GIT properly.
-Luckily Git comes with excellent documentation.
-
-  git --help
-  man git
-
-shows you the available subcommands,
-
-  git <command> --help
-  man git-<command>
-
-shows information about the subcommand <command>.
-
-The most comprehensive manual is the website Git Reference
-
-http://gitref.org/
-
-For more information about the Git project, visit
-
-http://git-scm.com/
-
-Consult these resources whenever you have problems, they are quite exhaustive.
-
-You do not need a special username or password.
-All you need is to provide a ssh public key to the Git server admin.
-
-What follows now is a basic introduction to Git and some FFmpeg-specific
-guidelines. Read it at least once, if you are granted commit privileges to the
-FFmpeg project you are expected to be familiar with these rules.
-
-
-
-I. BASICS:
-==========
-
-0. Get GIT:
-
-  You can get git from http://git-scm.com/
-
-
-1. Cloning the source tree:
-
-    git clone git://git.videolan.org/ffmpeg <target>
-
-  This will put the FFmpeg sources into the directory <target>.
-
-    git clone git@git.videolan.org:ffmpeg <target>
-
-  This will put the FFmpeg sources into the directory <target> and let
-  you push back your changes to the remote repository.
-
-
-2. Updating the source tree to the latest revision:
-
-    git pull (--ff-only)
-
-  pulls in the latest changes from the tracked branch. The tracked branch
-  can be remote. By default the master branch tracks the branch master in
-  the remote origin.
-  Caveat: Since merge commits are forbidden at least for the initial
-          months of git --ff-only or --rebase (see below) are recommended.
-          --ff-only will fail and not create merge commits if your branch
-          has diverged (has a different history) from the tracked branch.
-
-2.a Rebasing your local branches:
-
-    git pull --rebase
-
-  fetches the changes from the main repository and replays your local commits
-  over it. This is required to keep all your local changes at the top of
-  FFmpeg's master tree. The master tree will reject pushes with merge commits.
-
-
-3. Adding/removing files/directories:
-
-    git add [-A] <filename/dirname>
-    git rm [-r] <filename/dirname>
-
-  GIT needs to get notified of all changes you make to your working
-  directory that makes files appear or disappear.
-  Line moves across files are automatically tracked.
-
-
-4. Showing modifications:
-
-    git diff <filename(s)>
-
-  will show all local modifications in your working directory as unified diff.
-
-
-5. Inspecting the changelog:
-
-    git log <filename(s)>
-
-  You may also use the graphical tools like gitview or gitk or the web
-  interface available at http://git.videolan.org
-
-6. Checking source tree status:
-
-    git status
-
-  detects all the changes you made and lists what actions will be taken in case
-  of a commit (additions, modifications, deletions, etc.).
-
-
-7. Committing:
-
-    git diff --check
-
-  to double check your changes before committing them to avoid trouble later
-  on. All experienced developers do this on each and every commit, no matter
-  how small.
-  Every one of them has been saved from looking like a fool by this many times.
-  It's very easy for stray debug output or cosmetic modifications to slip in,
-  please avoid problems through this extra level of scrutiny.
-
-  For cosmetics-only commits you should get (almost) empty output from
-
-    git diff -w -b <filename(s)>
-
-  Also check the output of
-
-    git status
-
-  to make sure you don't have untracked files or deletions.
-
-    git add [-i|-p|-A] <filenames/dirnames>
-
-  Make sure you have told git your name and email address, e.g. by running
-    git config --global user.name "My Name"
-    git config --global user.email my@email.invalid
-  (--global to set the global configuration for all your git checkouts).
-
-  Git will select the changes to the files for commit. Optionally you can use
-  the interactive or the patch mode to select hunk by hunk what should be
-  added to the commit.
-
-    git commit
-
-  Git will commit the selected changes to your current local branch.
-
-  You will be prompted for a log message in an editor, which is either
-  set in your personal configuration file through
-
-    git config core.editor
-
-  or set by one of the following environment variables:
-  GIT_EDITOR, VISUAL or EDITOR.
-
-  Log messages should be concise but descriptive. Explain why you made a change,
-  what you did will be obvious from the changes themselves most of the time.
-  Saying just "bug fix" or "10l" is bad. Remember that people of varying skill
-  levels look at and educate themselves while reading through your code. Don't
-  include filenames in log messages, Git provides that information.
-
-  Possibly make the commit message have a terse, descriptive first line, an
-  empty line and then a full description. The first line will be used to name
-  the patch by git format-patch.
-
-
-8. Renaming/moving/copying files or contents of files:
-
-  Git automatically tracks such changes, making those normal commits.
-
-    mv/cp path/file otherpath/otherfile
-
-    git add [-A] .
-
-    git commit
-
-  Do not move, rename or copy files of which you are not the maintainer without
-  discussing it on the mailing list first!
-
-9. Reverting broken commits
-
-    git revert <commit>
-
-  git revert will generate a revert commit. This will not make the faulty
-  commit disappear from the history.
-
-    git reset <commit>
-
-  git reset will uncommit the changes till <commit> rewriting the current
-  branch history.
-
-    git commit --amend
-
-  allows to amend the last commit details quickly.
-
-    git rebase -i origin/master
-
-  will replay local commits over the main repository allowing to edit,
-  merge or remove some of them in the process.
-
-  Note that the reset, commit --amend and rebase rewrite history, so you
-  should use them ONLY on your local or topic branches.
-
-  The main repository will reject those changes.
-
-10. Preparing a patchset.
-
-    git format-patch <commit> [-o directory]
-
-  will generate a set of patches out of the current branch starting from
-  commit. By default the patches are created in the current directory.
-
-11. Sending patches for review
-
-    git send-email <commit list|directory>
-
-  will send the patches created by git format-patch or directly generates
-  them. All the email fields can be configured in the global/local
-  configuration or overridden by command line.
-
-12. Pushing changes to remote trees
-
-    git push
-
-  Will push the changes to the default remote (origin).
-  Git will prevent you from pushing changes if the local and remote trees are
-  out of sync. Refer to 2 and 2.a to sync the local tree.
-
-    git remote add <name> <url>
-
-  Will add additional remote with a name reference, it is useful if you want
-  to push your local branch for review on a remote host.
-
-    git push <remote> <refspec>
-
-  Will push the changes to the remote repository. Omitting refspec makes git
-  push update all the remote branches matching the local ones.
-
-13. Finding a specific svn revision
-
-  Since version 1.7.1 git supports ':/foo' syntax for specifying commits
-  based on a regular expression. see man gitrevisions
-
-    git show :/'as revision 23456'
-
-  will show the svn changeset r23456. With older git versions searching in
-  the git log output is the easiest option (especially if a pager with
-  search capabilities is used).
-  This commit can be checked out with
-
-    git checkout -b svn_23456 :/'as revision 23456'
-
-  or for git < 1.7.1 with
-
-    git checkout -b svn_23456 $SHA1
-
-  where $SHA1 is the commit SHA1 from the 'git log' output.
-
-
-Contact the project admins <root at ffmpeg dot org> if you have technical
-problems with the GIT server.

-@chapter Input Devices
-@c man begin INPUT DEVICES
-
-Input devices are configured elements in FFmpeg which allow to access
-the data coming from a multimedia device attached to your system.
-
-When you configure your FFmpeg build, all the supported input devices
-are enabled by default. You can list all available ones using the
-configure option "--list-indevs".
-
-You can disable all the input devices using the configure option
-"--disable-indevs", and selectively enable an input device using the
-option "--enable-indev=@var{INDEV}", or you can disable a particular
-input device using the option "--disable-indev=@var{INDEV}".
-
-The option "-formats" of the ff* tools will display the list of
-supported input devices (amongst the demuxers).
-
-A description of the currently available input devices follows.
-
-@section alsa
-
-ALSA (Advanced Linux Sound Architecture) input device.
-
-To enable this input device during configuration you need libasound
-installed on your system.
-
-This device allows capturing from an ALSA device. The name of the
-device to capture has to be an ALSA card identifier.
-
-An ALSA identifier has the syntax:
-@example
-hw:@var{CARD}[,@var{DEV}[,@var{SUBDEV}]]
-@end example
-
-where the @var{DEV} and @var{SUBDEV} components are optional.
-
-The three arguments (in order: @var{CARD},@var{DEV},@var{SUBDEV})
-specify card number or identifier, device number and subdevice number
-(-1 means any).
-
-To see the list of cards currently recognized by your system check the
-files @file{/proc/asound/cards} and @file{/proc/asound/devices}.
-
-For example to capture with @file{ffmpeg} from an ALSA device with
-card id 0, you may run the command:
-@example
-ffmpeg -f alsa -i hw:0 alsaout.wav
-@end example
-
-For more information see:
-@url{http://www.alsa-project.org/alsa-doc/alsa-lib/pcm.html}
-
-@section bktr
-
-BSD video input device.
-
-@section dv1394
-
-Linux DV 1394 input device.
-
-@section fbdev
-
-Linux framebuffer input device.
-
-The Linux framebuffer is a graphic hardware-independent abstraction
-layer to show graphics on a computer monitor, typically on the
-console. It is accessed through a file device node, usually
-@file{/dev/fb0}.
-
-For more detailed information read the file
-Documentation/fb/framebuffer.txt included in the Linux source tree.
-
-To record from the framebuffer device @file{/dev/fb0} with
-@file{ffmpeg}:
-@example
-ffmpeg -f fbdev -r 10 -i /dev/fb0 out.avi
-@end example
-
-You can take a single screenshot image with the command:
-@example
-ffmpeg -f fbdev -vframes 1 -r 1 -i /dev/fb0 screenshot.jpeg
-@end example
-
-See also @url{http://linux-fbdev.sourceforge.net/}, and fbset(1).
-
-@section jack
-
-JACK input device.
-
-To enable this input device during configuration you need libjack
-installed on your system.
-
-A JACK input device creates one or more JACK writable clients, one for
-each audio channel, with name @var{client_name}:input_@var{N}, where
-@var{client_name} is the name provided by the application, and @var{N}
-is a number which identifies the channel.
-Each writable client will send the acquired data to the FFmpeg input
-device.
-
-Once you have created one or more JACK readable clients, you need to
-connect them to one or more JACK writable clients.
-
-To connect or disconnect JACK clients you can use the
-@file{jack_connect} and @file{jack_disconnect} programs, or do it
-through a graphical interface, for example with @file{qjackctl}.
-
-To list the JACK clients and their properties you can invoke the command
-@file{jack_lsp}.

-@section libdc1394
-
-IIDC1394 input device, based on libdc1394 and libraw1394.
-
-@section openal
-
-The OpenAL input device provides audio capture on all systems with a
-working OpenAL 1.1 implementation.
-
-To enable this input device during configuration, you need OpenAL
-headers and libraries installed on your system, and need to configure
-FFmpeg with @code{--enable-openal}.
-
-OpenAL headers and libraries should be provided as part of your OpenAL
-implementation, or as an additional download (an SDK). Depending on your
-installation you may need to specify additional flags via the
-@code{--extra-cflags} and @code{--extra-ldflags} for allowing the build
-system to locate the OpenAL headers and libraries.
-
-An incomplete list of OpenAL implementations follows:
-
-@table @strong
-@item Creative
-The official Windows implementation, providing hardware acceleration
-with supported devices and software fallback.
-See @url{http://openal.org/}.
-@item OpenAL Soft
-Portable, open source (LGPL) software implementation. Includes
-backends for the most common sound APIs on the Windows, Linux,
-Solaris, and BSD operating systems.
-See @url{http://kcat.strangesoft.net/openal.html}.
-@item Apple
-OpenAL is part of Core Audio, the official Mac OS X Audio interface.
-See @url{http://developer.apple.com/technologies/mac/audio-and-video.html}
-@end table
-
-This device allows to capture from an audio input device handled
-through OpenAL.
-
-You need to specify the name of the device to capture in the provided
-filename. If the empty string is provided, the device will
-automatically select the default device. You can get the list of the
-supported devices by using the option @var{list_devices}.
-
-@subsection Options
-
-@table @option
-
-@item channels
-Set the number of channels in the captured audio. Only the values
-@option{1} (monaural) and @option{2} (stereo) are currently supported.
-Defaults to @option{2}.
-
-@item sample_size
-Set the sample size (in bits) of the captured audio. Only the values
-@option{8} and @option{16} are currently supported. Defaults to
-@option{16}.
-
-@item sample_rate
-Set the sample rate (in Hz) of the captured audio.
-Defaults to @option{44.1k}.
-
-@item list_devices
-If set to @option{true}, print a list of devices and exit.
-Defaults to @option{false}.
-
-@end table
-
-@subsection Examples
-
-Print the list of OpenAL supported devices and exit:
-@example
-$ ffmpeg -list_devices true -f openal -i dummy out.ogg
-@end example
-
-Capture from the OpenAL device @file{DR-BT101 via PulseAudio}:
-@example
-$ ffmpeg -f openal -i 'DR-BT101 via PulseAudio' out.ogg
-@end example
-
-Capture from the default device (note the empty string '' as filename):
-@example
-$ ffmpeg -f openal -i '' out.ogg
-@end example
-
-Capture from two devices simultaneously, writing to two different files,
-within the same @file{ffmpeg} command:
-@example
-$ ffmpeg -f openal -i 'DR-BT101 via PulseAudio' out1.ogg -f openal -i 'ALSA Default' out2.ogg
-@end example
-Note: not all OpenAL implementations support multiple simultaneous capture -
-try the latest OpenAL Soft if the above does not work.
-
-@section oss
-
-Open Sound System input device.
-
-The filename to provide to the input device is the device node
-representing the OSS input device, and is usually set to
-@file{/dev/dsp}.
-
-For example to grab from @file{/dev/dsp} using @file{ffmpeg} use the
-command:
-@example
-ffmpeg -f oss -i /dev/dsp /tmp/oss.wav
-@end example
-
-For more information about OSS see:
-@url{http://manuals.opensound.com/usersguide/dsp.html}
-
-@section sndio
-
-sndio input device.
-
-To enable this input device during configuration you need libsndio
-installed on your system.
-
-The filename to provide to the input device is the device node
-representing the sndio input device, and is usually set to
-@file{/dev/audio0}.
-
-For example to grab from @file{/dev/audio0} using @file{ffmpeg} use the
-command:
-@example
-ffmpeg -f sndio -i /dev/audio0 /tmp/oss.wav
-@end example
-
-@section video4linux and video4linux2
-
-Video4Linux and Video4Linux2 input video devices.
-
-The name of the device to grab is a file device node, usually Linux
-systems tend to automatically create such nodes when the device
-(e.g. an USB webcam) is plugged into the system, and has a name of the
-kind @file{/dev/video@var{N}}, where @var{N} is a number associated to
-the device.
-
-Video4Linux and Video4Linux2 devices only support a limited set of
-@var{width}x@var{height} sizes and framerates. You can check which are
-supported for example with the command @file{dov4l} for Video4Linux
-devices and the command @file{v4l-info} for Video4Linux2 devices.
-
-If the size for the device is set to 0x0, the input device will
-try to autodetect the size to use.
-Only for the video4linux2 device, if the frame rate is set to 0/0 the
-input device will use the frame rate value already set in the driver.
-
-Video4Linux support is deprecated since Linux 2.6.30, and will be
-dropped in later versions.
-
-Follow some usage examples of the video4linux devices with the ff*
-tools.
-@example
-# Grab and show the input of a video4linux device, frame rate is set
-# to the default of 25/1.
-ffplay -s 320x240 -f video4linux /dev/video0
-
-# Grab and show the input of a video4linux2 device, autoadjust size.
-ffplay -f video4linux2 /dev/video0
-
-# Grab and record the input of a video4linux2 device, autoadjust size,
-# frame rate value defaults to 0/0 so it is read from the video4linux2
-# driver.
-ffmpeg -f video4linux2 -i /dev/video0 out.mpeg
-@end example
-
-@section vfwcap
-
-VfW (Video for Windows) capture input device.
-
-The filename passed as input is the capture driver number, ranging from
-0 to 9. You may use "list" as filename to print a list of drivers. Any
-other filename will be interpreted as device number 0.
-
-@section x11grab
-
-X11 video input device.
-
-This device allows to capture a region of an X11 display.
-
-The filename passed as input has the syntax:
-@example
-[@var{hostname}]:@var{display_number}.@var{screen_number}[+@var{x_offset},@var{y_offset}]
-@end example
-
-@var{hostname}:@var{display_number}.@var{screen_number} specifies the
-X11 display name of the screen to grab from. @var{hostname} can be
-ommitted, and defaults to "localhost". The environment variable
-@env{DISPLAY} contains the default display name.
-
-@var{x_offset} and @var{y_offset} specify the offsets of the grabbed
-area with respect to the top-left border of the X11 screen. They
-default to 0.
-
-Check the X11 documentation (e.g. man X) for more detailed information.
-
-Use the @file{dpyinfo} program for getting basic information about the
-properties of your X11 display (e.g. grep for "name" or "dimensions").
-
-For example to grab from @file{:0.0} using @file{ffmpeg}:
-@example
-ffmpeg -f x11grab -r 25 -s cif -i :0.0 out.mpg
-
-# Grab at position 10,20.
-ffmpeg -f x11grab -r 25 -s cif -i :0.0+10,20 out.mpg
-@end example
-
-@subsection @var{follow_mouse} AVOption
-
-The syntax is:
-@example
--follow_mouse centered|@var{PIXELS}
-@end example
-
-When it is specified with "centered", the grabbing region follows the mouse
-pointer and keeps the pointer at the center of region; otherwise, the region
-follows only when the mouse pointer reaches within @var{PIXELS} (greater than
-zero) to the edge of region.
-
-For example:
-@example
-ffmpeg -f x11grab -follow_mouse centered -r 25 -s cif -i :0.0 out.mpg
-
-# Follows only when the mouse pointer reaches within 100 pixels to edge
-ffmpeg -f x11grab -follow_mouse 100 -r 25 -s cif -i :0.0 out.mpg
-@end example
-
-@subsection @var{show_region} AVOption
-
-The syntax is:
-@example
--show_region 1
-@end example
-
-If @var{show_region} AVOption is specified with @var{1}, then the grabbing
-region will be indicated on screen. With this option, it's easy to know what is
-being grabbed if only a portion of the screen is grabbed.
-
-For example:
-@example
-ffmpeg -f x11grab -show_region 1 -r 25 -s cif -i :0.0+10,20 out.mpg
-
-# With follow_mouse
-ffmpeg -f x11grab -follow_mouse centered -show_region 1  -r 25 -s cif -i :0.0 out.mpg
-@end example
-
-@c man end INPUT DEVICES

-FFmpeg's bug/patch/feature request tracker manual
-=================================================
-
-NOTE: This is a draft.
-
-Overview:
----------
-FFmpeg uses Trac for tracking issues, new issues and changes to
-existing issues can be done through a web interface.
-It is possible to subscribe to individual issues by adding yourself to the
-nosy list or to subscribe to the ffmpeg-issues mailing list which receives
-a mail for every change to every issue. Replies to such mails will also
-be properly added to the respective issue.
-(the above does all work already after light testing)
-The subscription URL for the ffmpeg-trac list is:
-http(s)://ffmpeg.org/mailman/listinfo/ffmpeg-trac
-The URL of the webinterface of the tracker is:
-http(s)://ffmpeg.org/trac/ffmpeg
-
-NOTE: issue = (bug report || patch || feature request)
-
-Type:
------
-bug
-    An error, flaw, mistake, failure, or fault in FFmpeg or libav* that
-    prevents it from behaving as intended.
-
-feature request
-    Request of support for encoding or decoding of a new codec, container
-    or variant.
-    Request of support for more, less or plain different output or behavior
-    where the current implementation cannot be considered wrong.
-
-patch
-    A patch as generated by diff which conforms to the patch submission and
-    development policy.
-
-
-Priority:
----------
-critical
-    Bugs and patches which deal with data loss and security issues.
-    No feature request can be critical.
-
-important
-    Bugs which make FFmpeg unusable for a significant number of users, and
-    patches fixing them.
-    Examples here might be completely broken MPEG-4 decoding or a build issue
-    on Linux.
-    While broken 4xm decoding or a broken OS/2 build would not be important,
-    the separation to normal is somewhat fuzzy.
-    For feature requests this priority would be used for things many people
-    want.
-
-normal
-
-
-minor
-    Bugs and patches about things like spelling errors, "mp2" instead of
-    "mp3" being shown and such.
-    Feature requests about things few people want or which do not make a big
-    difference.
-
-wish
-    Something that is desirable to have but that there is no urgency at
-    all to implement, e.g. something completely cosmetic like a website
-    restyle or a personalized doxy template or the FFmpeg logo.
-    This priority is not valid for bugs.
-
-
-Status:
--------

-
-
-Type/Status/Substatus:
-----------
-*/new/new
-    Initial state of new bugs, patches and feature requests submitted by
-    users.
-
-*/open/open
-    Issues which have been briefly looked at and which did not look outright
-    invalid.
-    This implicates that no real more detailed state applies yet. Conversely,
-    the more detailed states below implicate that the issue has been briefly
-    looked at.
-
-*/closed/duplicate
-    Bugs, patches or feature requests which are duplicates.
-    Note that patches dealing with the same thing in a different way are not
-    duplicates.
-    Note, if you mark something as duplicate, do not forget setting the
-    superseder so bug reports are properly linked.
-
-*/closed/invalid
-    Bugs caused by user errors, random ineligible or otherwise nonsense stuff.
-
-*/closed/needs_more_info
-    Issues for which some information has been requested by the developers,
-    but which has not been provided by anyone within reasonable time.
-
-bug/open/reproduced
-    Bugs which have been reproduced.
-
-bug/open/analyzed
-    Bugs which have been analyzed and where it is understood what causes them
-    and which exact chain of events triggers them. This analysis should be
-    available as a message in the bug report.
-    Note, do not change the status to analyzed without also providing a clear
-    and understandable analysis.
-    This state implicates that the bug either has been reproduced or that
-    reproduction is not needed as the bug is already understood.
-
-bug/open/needs_more_info
-    Bug reports which are incomplete and or where more information is needed
-    from the submitter or another person who can provide it.
-    This state implicates that the bug has not been analyzed or reproduced.
-    Note, the idea behind needs_more_info is to offload work from the
-    developers to the users whenever possible.
-
-bug/closed/fixed
-    Bugs which have to the best of our knowledge been fixed.
-
-bug/closed/wont_fix
-    Bugs which we will not fix. Possible reasons include legality, high
-    complexity for the sake of supporting obscure corner cases, speed loss
-    for similarly esoteric purposes, et cetera.
-    This also means that we would reject a patch.
-    If we are just too lazy to fix a bug then the correct state is open
-    and unassigned. Closed means that the case is closed which is not
-    the case if we are just waiting for a patch.
-
-bug/closed/works_for_me
-    Bugs for which sufficient information was provided to reproduce but
-    reproduction failed - that is the code seems to work correctly to the
-    best of our knowledge.
-
-patch/open/approved
-    Patches which have been reviewed and approved by a developer.
-    Such patches can be applied anytime by any other developer after some
-    reasonable testing (compile + regression tests + does the patch do
-    what the author claimed).
-
-patch/open/needs_changes
-    Patches which have been reviewed and need changes to be accepted.
-
-patch/closed/applied
-    Patches which have been applied.
-
-patch/closed/rejected
-    Patches which have been rejected.
-
-feature_request/open/needs_more_info
-    Feature requests where it is not clear what exactly is wanted
-    (these also could be closed as invalid ...).
-
-feature_request/closed/implemented
-    Feature requests which have been implemented.
-
-feature_request/closed/wont_implement
-    Feature requests which will not be implemented. The reasons here could
-    be legal, philosophical or others.
-
-Note, please do not use type-status-substatus combinations other than the
-above without asking on ffmpeg-dev first!

-@chapter Introduction
-
-Libavfilter is the filtering API of FFmpeg. It is the substitute of the
-now deprecated 'vhooks' and started as a Google Summer of Code project.
-
-Integrating libavfilter into the main FFmpeg repository is a work in
-progress. If you wish to try the unfinished development code of
-libavfilter then check it out from the libavfilter repository into
-some directory of your choice by:
-
-@example
-   svn checkout svn://svn.ffmpeg.org/soc/libavfilter
-@end example
-
-And then read the README file in the top directory to learn how to
-integrate it into ffmpeg and ffplay.
-
-But note that there may still be serious bugs in the code and its API
-and ABI should not be considered stable yet!
-
-@chapter Tutorial
-
-In libavfilter, it is possible for filters to have multiple inputs and
-multiple outputs.
-To illustrate the sorts of things that are possible, we can
-use a complex filter graph. For example, the following one:
-
-@example
-input --> split --> fifo -----------------------> overlay --> output
-            |                                        ^
-            |                                        |
-            +------> fifo --> crop --> vflip --------+
-@end example
-
-splits the stream in two streams, sends one stream through the crop filter
-and the vflip filter before merging it back with the other stream by
-overlaying it on top. You can use the following command to achieve this:
-
-@example
-./ffmpeg -i in.avi -s 240x320 -vf "[in] split [T1], fifo, [T2] overlay= 0:240 [out]; [T1] fifo, crop=0:0:-1:240, vflip [T2]
-@end example
-
-where input_video.avi has a vertical resolution of 480 pixels. The
-result will be that in output the top half of the video is mirrored
-onto the bottom half.
-
-Video filters are loaded using the @var{-vf} option passed to
-ffmpeg or to ffplay. Filters in the same linear chain are separated by
-commas. In our example, @var{split, fifo, overlay} are in one linear
-chain, and @var{fifo, crop, vflip} are in another. The points where
-the linear chains join are labeled by names enclosed in square
-brackets. In our example, that is @var{[T1]} and @var{[T2]}. The magic
-labels @var{[in]} and @var{[out]} are the points where video is input
-and output.
-
-Some filters take in input a list of parameters: they are specified
-after the filter name and an equal sign, and are separated each other
-by a semicolon.
-
-There exist so-called @var{source filters} that do not have a video
-input, and we expect in the future some @var{sink filters} that will
-not have video output.
-
-@chapter graph2dot
-
-The @file{graph2dot} program included in the FFmpeg @file{tools}
-directory can be used to parse a filter graph description and issue a
-corresponding textual representation in the dot language.
-
-Invoke the command:
-@example
-graph2dot -h
-@end example
-
-to see how to use @file{graph2dot}.
-
-You can then pass the dot description to the @file{dot} program (from
-the graphviz suite of programs) and obtain a graphical representation
-of the filter graph.
-
-For example the sequence of commands:
-@example
-echo @var{GRAPH_DESCRIPTION} | \
-tools/graph2dot -o graph.tmp && \
-dot -Tpng graph.tmp -o graph.png && \
-display graph.png
-@end example
-
-can be used to create and display an image representing the graph
-described by the @var{GRAPH_DESCRIPTION} string.

-@chapter Metadata
-@c man begin METADATA
-
-FFmpeg is able to dump metadata from media files into a simple UTF-8-encoded
-INI-like text file and then load it back using the metadata muxer/demuxer.
-
-The file format is as follows:
-@enumerate
-
-@item
-A file consists of a header and a number of metadata tags divided into sections,
-each on its own line.
-
-@item
-The header is a ';FFMETADATA' string, followed by a version number (now 1).
-
-@item
-Metadata tags are of the form 'key=value'
-
-@item
-Immediately after header follows global metadata
-
-@item
-After global metadata there may be sections with per-stream/per-chapter
-metadata.
-
-@item
-A section starts with the section name in uppercase (i.e. STREAM or CHAPTER) in
-brackets ('[', ']') and ends with next section or end of file.
-
-@item
-At the beginning of a chapter section there may be an optional timebase to be
-used for start/end values. It must be in form 'TIMEBASE=num/den', where num and
-den are integers. If the timebase is missing then start/end times are assumed to
-be in milliseconds.
-Next a chapter section must contain chapter start and end times in form
-'START=num', 'END=num', where num is a positive integer.
-
-@item
-Empty lines and lines starting with ';' or '#' are ignored.
-
-@item
-Metadata keys or values containing special characters ('=', ';', '#', '\' and a
-newline) must be escaped with a backslash '\'.
-
-@item
-Note that whitespace in metadata (e.g. foo = bar) is considered to be a part of
-the tag (in the example above key is 'foo ', value is ' bar').

-FFmpeg multithreading methods
-==============================================
-
-FFmpeg provides two methods for multithreading codecs.
-
-Slice threading decodes multiple parts of a frame at the same time, using
-AVCodecContext execute() and execute2().
-
-Frame threading decodes multiple frames at the same time.
-It accepts N future frames and delays decoded pictures by N-1 frames.
-The later frames are decoded in separate threads while the user is
-displaying the current one.
-
-Restrictions on clients
-==============================================
-
-Slice threading -
-* The client's draw_horiz_band() must be thread-safe according to the comment
-  in avcodec.h.
-
-Frame threading -
-* Restrictions with slice threading also apply.
-* For best performance, the client should set thread_safe_callbacks if it
-  provides a thread-safe get_buffer() callback.
-* There is one frame of delay added for every thread beyond the first one.
-  Clients must be able to handle this; the pkt_dts and pkt_pts fields in
-  AVFrame will work as usual.
-
-Restrictions on codec implementations
-==============================================
-
-Slice threading -
- None except that there must be something worth executing in parallel.
-
-Frame threading -
-* Codecs can only accept entire pictures per packet.
-* Codecs similar to ffv1, whose streams don't reset across frames,
-  will not work because their bitstreams cannot be decoded in parallel.
-
-* The contents of buffers must not be read before ff_thread_await_progress()
-  has been called on them. reget_buffer() and buffer age optimizations no longer work.
-* The contents of buffers must not be written to after ff_thread_report_progress()
-  has been called on them. This includes draw_edges().
-
-Porting codecs to frame threading
-==============================================
-
-Find all context variables that are needed by the next frame. Move all
-code changing them, as well as code calling get_buffer(), up to before
-the decode process starts. Call ff_thread_finish_setup() afterwards. If
-some code can't be moved, have update_thread_context() run it in the next
-thread.
-
-If the codec allocates writable tables in its init(), add an init_thread_copy()
-which re-allocates them for other threads.
-
-Add CODEC_CAP_FRAME_THREADS to the codec capabilities. There will be very little
-speed gain at this point but it should work.
-
-Call ff_thread_report_progress() after some part of the current picture has decoded.
-A good place to put this is where draw_horiz_band() is called - add this if it isn't
-called anywhere, as it's useful too and the implementation is trivial when you're
-doing this. Note that draw_edges() needs to be called before reporting progress.
-
-Before accessing a reference frame or its MVs, call ff_thread_await_progress().

-configure option @code{--list-muxers}.
-
-You can disable all the muxers with the configure option
-@code{--disable-muxers} and selectively enable / disable single muxers
-with the options @code{--enable-muxer=@var{MUXER}} /
-@code{--disable-muxer=@var{MUXER}}.
-
-The option @code{-formats} of the ff* tools will display the list of
-enabled muxers.
-
-A description of some of the currently available muxers follows.
-
-@anchor{crc}
-@section crc
-
-CRC (Cyclic Redundancy Check) testing format.
-
-This muxer computes and prints the Adler-32 CRC of all the input audio
-and video frames. By default audio frames are converted to signed
-16-bit raw audio and video frames to raw video before computing the
-CRC.
-
-The output of the muxer consists of a single line of the form:
-CRC=0x@var{CRC}, where @var{CRC} is a hexadecimal number 0-padded to
-8 digits containing the CRC for all the decoded input frames.
-
-For example to compute the CRC of the input, and store it in the file
-@file{out.crc}:
-@example
-ffmpeg -i INPUT -f crc out.crc
-@end example
-
-You can print the CRC to stdout with the command:
-@example
-ffmpeg -i INPUT -f crc -
-@end example
-
-You can select the output format of each frame with @file{ffmpeg} by
-specifying the audio and video codec and format. For example to
-compute the CRC of the input audio converted to PCM unsigned 8-bit
-and the input video converted to MPEG-2 video, use the command:
-@example
-ffmpeg -i INPUT -acodec pcm_u8 -vcodec mpeg2video -f crc -
-@end example
-
-See also the @ref{framecrc} muxer.
-
-@anchor{framecrc}
-@section framecrc
-
-Per-frame CRC (Cyclic Redundancy Check) testing format.
-
-This muxer computes and prints the Adler-32 CRC for each decoded audio
-and video frame. By default audio frames are converted to signed
-16-bit raw audio and video frames to raw video before computing the
-CRC.
-
-The output of the muxer consists of a line for each audio and video
-frame of the form: @var{stream_index}, @var{frame_dts},
-@var{frame_size}, 0x@var{CRC}, where @var{CRC} is a hexadecimal
-number 0-padded to 8 digits containing the CRC of the decoded frame.
-
-For example to compute the CRC of each decoded frame in the input, and
-store it in the file @file{out.crc}:
-@example
-ffmpeg -i INPUT -f framecrc out.crc
-@end example
-
-You can print the CRC of each decoded frame to stdout with the command:
-@example
-ffmpeg -i INPUT -f framecrc -
-@end example
-
-You can select the output format of each frame with @file{ffmpeg} by
-specifying the audio and video codec and format. For example, to
-compute the CRC of each decoded input audio frame converted to PCM
-unsigned 8-bit and of each decoded input video frame converted to
-MPEG-2 video, use the command:
-@example
-ffmpeg -i INPUT -acodec pcm_u8 -vcodec mpeg2video -f framecrc -
-@end example
-
-See also the @ref{crc} muxer.
-
-@section image2
-
-Image file muxer.
-
-The image file muxer writes video frames to image files.
-
-The output filenames are specified by a pattern, which can be used to
-produce sequentially numbered series of files.
-The pattern may contain the string "%d" or "%0@var{N}d", this string
-specifies the position of the characters representing a numbering in
-the filenames. If the form "%0@var{N}d" is used, the string
-representing the number in each filename is 0-padded to @var{N}
-digits. The literal character '%' can be specified in the pattern with
-the string "%%".
-
-If the pattern contains "%d" or "%0@var{N}d", the first filename of
-the file list specified will contain the number 1, all the following
-numbers will be sequential.
-
-The pattern may contain a suffix which is used to automatically
-determine the format of the image files to write.
-
-For example the pattern "img-%03d.bmp" will specify a sequence of
-filenames of the form @file{img-001.bmp}, @file{img-002.bmp}, ...,
-@file{img-010.bmp}, etc.
-The pattern "img%%-%d.jpg" will specify a sequence of filenames of the
-form @file{img%-1.jpg}, @file{img%-2.jpg}, ..., @file{img%-10.jpg},
-etc.
-
-The following example shows how to use @file{ffmpeg} for creating a
-sequence of files @file{img-001.jpeg}, @file{img-002.jpeg}, ...,
-taking one image every second from the input video:
-@example
-ffmpeg -i in.avi -r 1 -f image2 'img-%03d.jpeg'
-@end example
-
-Note that with @file{ffmpeg}, if the format is not specified with the
-@code{-f} option and the output filename specifies an image file
-format, the image2 muxer is automatically selected, so the previous
-command can be written as:
-@example
-ffmpeg -i in.avi -r 1 'img-%03d.jpeg'
-@end example
-
-Note also that the pattern must not necessarily contain "%d" or
-"%0@var{N}d", for example to create a single image file
-@file{img.jpeg} from the input video you can employ the command:
-@example
-ffmpeg -i in.avi -f image2 -vframes 1 img.jpeg
-@end example
-
-The image muxer supports the .Y.U.V image file format. This format is
-special in that that each image frame consists of three files, for
-each of the YUV420P components. To read or write this image file format,
-specify the name of the '.Y' file. The muxer will automatically open the
-'.U' and '.V' files as required.
-
-@section mpegts
-
-MPEG transport stream muxer.
-
-This muxer implements ISO 13818-1 and part of ETSI EN 300 468.
-
-The muxer options are:
-
-@table @option
-@item -mpegts_original_network_id @var{number}
-Set the original_network_id (default 0x0001). This is unique identifier
-of a network in DVB. Its main use is in the unique identification of a
-service through the path Original_Network_ID, Transport_Stream_ID.
-@item -mpegts_transport_stream_id @var{number}
-Set the transport_stream_id (default 0x0001). This identifies a
-transponder in DVB.
-@item -mpegts_service_id @var{number}
-Set the service_id (default 0x0001) also known as program in DVB.
-@item -mpegts_pmt_start_pid @var{number}
-Set the first PID for PMT (default 0x1000, max 0x1f00).
-@item -mpegts_start_pid @var{number}
-Set the first PID for data packets (default 0x0100, max 0x0f00).
-@end table
-
-The recognized metadata settings in mpegts muxer are @code{service_provider}
-and @code{service_name}. If they are not set the default for
-@code{service_provider} is "FFmpeg" and the default for
-@code{service_name} is "Service01".
-
-@example
-ffmpeg -i file.mpg -acodec copy -vcodec copy \
-     -mpegts_original_network_id 0x1122 \
-     -mpegts_transport_stream_id 0x3344 \

-     -metadata service_provider="Some provider" \
-     -metadata service_name="Some Channel" \
-     -y out.ts
-@end example
-
-@section null
-
-Null muxer.
-
-This muxer does not generate any output file, it is mainly useful for
-testing or benchmarking purposes.
-
-For example to benchmark decoding with @file{ffmpeg} you can use the
-command:
-@example
-ffmpeg -benchmark -i INPUT -f null out.null
-@end example
-
-Note that the above command does not read or write the @file{out.null}
-file, but specifying the output file is required by the @file{ffmpeg}
-syntax.
-
-Alternatively you can write the command as:
-@example
-ffmpeg -benchmark -i INPUT -f null -
-@end example

-optimization Tips (for libavcodec):
-===================================
-
-What to optimize:
------------------
-If you plan to do non-x86 architecture specific optimizations (SIMD normally),
-then take a look in the x86/ directory, as most important functions are
-already optimized for MMX.
-
-If you want to do x86 optimizations then you can either try to finetune the
-stuff in the x86 directory or find some other functions in the C source to
-optimize, but there aren't many left.
-
-
-Understanding these overoptimized functions:
---------------------------------------------
-As many functions tend to be a bit difficult to understand because
-of optimizations, it can be hard to optimize them further, or write
-architecture-specific versions. It is recommended to look at older
-revisions of the interesting files (web frontends for the various FFmpeg
-branches are listed at http://ffmpeg.org/download.html).
-Alternatively, look into the other architecture-specific versions in
-the x86/, ppc/, alpha/ subdirectories. Even if you don't exactly
-comprehend the instructions, it could help understanding the functions
-and how they can be optimized.
-
-NOTE: If you still don't understand some function, ask at our mailing list!!!
-(http://lists.ffmpeg.org/mailman/listinfo/ffmpeg-devel)
-
-
-When is an optimization justified?
-----------------------------------
-Normally, clean and simple optimizations for widely used codecs are
-justified even if they only achieve an overall speedup of 0.1%. These
-speedups accumulate and can make a big difference after awhile. Also, if
-none of the following factors get worse due to an optimization -- speed,
-binary code size, source size, source readability -- and at least one
-factor improves, then an optimization is always a good idea even if the
-overall gain is less than 0.1%. For obscure codecs that are not often
-used, the goal is more toward keeping the code clean, small, and
-readable instead of making it 1% faster.
-
-
-WTF is that function good for ....:
------------------------------------
-The primary purpose of this list is to avoid wasting time optimizing functions
-which are rarely used.
-
-put(_no_rnd)_pixels{,_x2,_y2,_xy2}
-    Used in motion compensation (en/decoding).
-
-avg_pixels{,_x2,_y2,_xy2}
-    Used in motion compensation of B-frames.
-    These are less important than the put*pixels functions.
-
-avg_no_rnd_pixels*
-    unused
-
-pix_abs16x16{,_x2,_y2,_xy2}
-    Used in motion estimation (encoding) with SAD.
-
-pix_abs8x8{,_x2,_y2,_xy2}
-    Used in motion estimation (encoding) with SAD of MPEG-4 4MV only.
-    These are less important than the pix_abs16x16* functions.
-
-put_mspel8_mc* / wmv2_mspel8*
-    Used only in WMV2.
-    it is not recommended that you waste your time with these, as WMV2
-    is an ugly and relatively useless codec.
-
-mpeg4_qpel* / *qpel_mc*
-    Used in MPEG-4 qpel motion compensation (encoding & decoding).
-    The qpel8 functions are used only for 4mv,
-    the avg_* functions are used only for B-frames.
-    Optimizing them should have a significant impact on qpel
-    encoding & decoding.
-
-qpel{8,16}_mc??_old_c / *pixels{8,16}_l4
-    Just used to work around a bug in an old libavcodec encoder version.
-    Don't optimize them.
-
-tpel_mc_func {put,avg}_tpel_pixels_tab
-    Used only for SVQ3, so only optimize them if you need fast SVQ3 decoding.
-
-add_bytes/diff_bytes
-    For huffyuv only, optimize if you want a faster ffhuffyuv codec.
-
-get_pixels / diff_pixels
-    Used for encoding, easy.
-
-clear_blocks
-    easiest to optimize
-
-gmc
-    Used for MPEG-4 gmc.
-    Optimizing this should have a significant effect on the gmc decoding
-    speed.
-
-gmc1
-    Used for chroma blocks in MPEG-4 gmc with 1 warp point
-    (there are 4 luma & 2 chroma blocks per macroblock, so
-    only 1/3 of the gmc blocks use this, the other 2/3
-    use the normal put_pixel* code, but only if there is
-    just 1 warp point).
-    Note: DivX5 gmc always uses just 1 warp point.
-
-pix_sum
-    Used for encoding.
-
-hadamard8_diff / sse / sad == pix_norm1 / dct_sad / quant_psnr / rd / bit
-    Specific compare functions used in encoding, it depends upon the
-    command line switches which of these are used.
-    Don't waste your time with dct_sad & quant_psnr, they aren't
-    really useful.
-
-put_pixels_clamped / add_pixels_clamped
-    Used for en/decoding in the IDCT, easy.
-    Note, some optimized IDCTs have the add/put clamped code included and
-    then put_pixels_clamped / add_pixels_clamped will be unused.
-
-idct/fdct
-    idct (encoding & decoding)
-    fdct (encoding)
-    difficult to optimize
-
-dct_quantize_trellis
-    Used for encoding with trellis quantization.
-    difficult to optimize
-
-dct_quantize
-    Used for encoding.
-
-dct_unquantize_mpeg1
-    Used in MPEG-1 en/decoding.
-
-dct_unquantize_mpeg2
-    Used in MPEG-2 en/decoding.
-
-dct_unquantize_h263
-    Used in MPEG-4/H.263 en/decoding.
-
-FIXME remaining functions?
-BTW, most of these functions are in dsputil.c/.h, some are in mpegvideo.c/.h.
-
-
-
-Alignment:
-Some instructions on some architectures have strict alignment restrictions,
-for example most SSE/SSE2 instructions on x86.
-The minimum guaranteed alignment is written in the .h files, for example:
-    void (*put_pixels_clamped)(const DCTELEM *block/*align 16*/, UINT8 *pixels/*align 8*/, int line_size);
-
-
-General Tips:
--------------
-Use asm loops like:
-__asm__(
-    "1: ....
-    ...
-    "jump_instruction ....
-Do not use C loops:
-do{
-    __asm__(
-        ...
-}while()
-
-For x86, mark registers that are clobbered in your asm. This means both
-general x86 registers (e.g. eax) as well as XMM registers. This last one is
-particularly important on Win64, where xmm6-15 are callee-save, and not
-restoring their contents leads to undefined results. In external asm (e.g.
-yasm), you do this by using:
-cglobal functon_name, num_args, num_regs, num_xmm_regs
-In inline asm, you specify clobbered registers at the end of your asm:
-__asm__(".." ::: "%eax").
-If gcc is not set to support sse (-msse) it will not accept xmm registers
-in the clobber list. For that we use two macros to declare the clobbers.
-XMM_CLOBBERS should be used when there are other clobbers, for example:
-__asm__(".." ::: XMM_CLOBBERS("xmm0",) "eax");
-and XMM_CLOBBERS_ONLY should be used when the only clobbers are xmm registers:
-__asm__(".." :: XMM_CLOBBERS_ONLY("xmm0"));
-
-Do not expect a compiler to maintain values in your registers between separate
-(inline) asm code blocks. It is not required to. For example, this is bad:
-__asm__("movdqa %0, %%xmm7" : src);
-/* do something */
-__asm__("movdqa %%xmm7, %1" : dst);
-- first of all, you're assuming that the compiler will not use xmm7 in
-   between the two asm blocks.  It probably won't when you test it, but it's
-   a poor assumption that will break at some point for some --cpu compiler flag
-- secondly, you didn't mark xmm7 as clobbered. If you did, the compiler would
-   have restored the original value of xmm7 after the first asm block, thus
-   rendering the combination of the two blocks of code invalid
-Code that depends on data in registries being untouched, should be written as
-a single __asm__() statement. Ideally, a single function contains only one
-__asm__() block.
-
-Use external asm (nasm/yasm) or inline asm (__asm__()), do not use intrinsics.
-The latter requires a good optimizing compiler which gcc is not.
-
-Inline asm vs. external asm
----------------------------
-Both inline asm (__asm__("..") in a .c file, handled by a compiler such as gcc)
-and external asm (.s or .asm files, handled by an assembler such as yasm/nasm)
-are accepted in FFmpeg. Which one to use differs per specific case.
-
-- if your code is intended to be inlined in a C function, inline asm is always
-   better, because external asm cannot be inlined
-- if your code calls external functions, yasm is always better
-- if your code takes huge and complex structs as function arguments (e.g.
-   MpegEncContext; note that this is not ideal and is discouraged if there
-   are alternatives), then inline asm is always better, because predicting
-   member offsets in complex structs is almost impossible. It's safest to let
-   the compiler take care of that
-- in many cases, both can be used and it just depends on the preference of the
-   person writing the asm. For new asm, the choice is up to you. For existing
-   asm, you'll likely want to maintain whatever form it is currently in unless
-   there is a good reason to change it.
-- if, for some reason, you believe that a particular chunk of existing external
-   asm could be improved upon further if written in inline asm (or the other
-   way around), then please make the move from external asm <-> inline asm a
-   separate patch before your patches that actually improve the asm.

-A description of the currently available protocols follows.
-
-@section applehttp
-
-Read Apple HTTP Live Streaming compliant segmented stream as
-a uniform one. The M3U8 playlists describing the segments can be
-remote HTTP resources or local files, accessed using the standard
-file protocol.
-HTTP is default, specific protocol can be declared by specifying
-"+@var{proto}" after the applehttp URI scheme name, where @var{proto}
-is either "file" or "http".
-
-@example
-applehttp://host/path/to/remote/resource.m3u8
-applehttp+http://host/path/to/remote/resource.m3u8
-applehttp+file://path/to/local/resource.m3u8
-@end example
-
-@section concat
-
-Physical concatenation protocol.
-
-Allow to read and seek from many resource in sequence as if they were
-a unique resource.
-
-A URL accepted by this protocol has the syntax:
-@example
-concat:@var{URL1}|@var{URL2}|...|@var{URLN}
-@end example
-
-where @var{URL1}, @var{URL2}, ..., @var{URLN} are the urls of the
-resource to be concatenated, each one possibly specifying a distinct
-protocol.
-
-For example to read a sequence of files @file{split1.mpeg},
-@file{split2.mpeg}, @file{split3.mpeg} with @file{ffplay} use the
-command:
-@example
-ffplay concat:split1.mpeg\|split2.mpeg\|split3.mpeg
-@end example
-
-Note that you may need to escape the character "|" which is special for
-many shells.
-
-@section file
-
-File access protocol.
-
-Allow to read from or read to a file.
-
-For example to read from a file @file{input.mpeg} with @file{ffmpeg}
-use the command:
-@example
-ffmpeg -i file:input.mpeg output.mpeg
-@end example
-
-The ff* tools default to the file protocol, that is a resource
-specified with the name "FILE.mpeg" is interpreted as the URL
-"file:FILE.mpeg".
-
-@section gopher
-
-Gopher protocol.
-
-@section http
-
-HTTP (Hyper Text Transfer Protocol).
-
-@section mmst
-
-MMS (Microsoft Media Server) protocol over TCP.
-
-@section mmsh
-
-MMS (Microsoft Media Server) protocol over HTTP.
-
-The required syntax is:
-@example
-mmsh://@var{server}[:@var{port}][/@var{app}][/@var{playpath}]
-@end example
-
-@section md5
-
-MD5 output protocol.
-
-Computes the MD5 hash of the data to be written, and on close writes
-this to the designated output or stdout if none is specified. It can
-be used to test muxers without writing an actual file.
-
-Some examples follow.
-@example
-# Write the MD5 hash of the encoded AVI file to the file output.avi.md5.
-ffmpeg -i input.flv -f avi -y md5:output.avi.md5
-
-# Write the MD5 hash of the encoded AVI file to stdout.
-ffmpeg -i input.flv -f avi -y md5:
-@end example
-
-Note that some formats (typically MOV) require the output protocol to
-be seekable, so they will fail with the MD5 output protocol.
-
-@section pipe
-
-UNIX pipe access protocol.
-
-Allow to read and write from UNIX pipes.
-
-The accepted syntax is:
-@example
-pipe:[@var{number}]
-@end example
-
-@var{number} is the number corresponding to the file descriptor of the
-pipe (e.g. 0 for stdin, 1 for stdout, 2 for stderr).  If @var{number}
-is not specified, by default the stdout file descriptor will be used
-for writing, stdin for reading.
-
-For example to read from stdin with @file{ffmpeg}:
-@example
-cat test.wav | ffmpeg -i pipe:0
-# ...this is the same as...
-cat test.wav | ffmpeg -i pipe:
-@end example
-
-For writing to stdout with @file{ffmpeg}:
-@example
-ffmpeg -i test.wav -f avi pipe:1 | cat > test.avi
-# ...this is the same as...
-ffmpeg -i test.wav -f avi pipe: | cat > test.avi
-@end example
-
-Note that some formats (typically MOV), require the output protocol to
-be seekable, so they will fail with the pipe output protocol.
-
-@section rtmp
-
-Real-Time Messaging Protocol.
-
-The Real-Time Messaging Protocol (RTMP) is used for streaming multime‐
-dia content across a TCP/IP network.
-
-The required syntax is:
-@example
-rtmp://@var{server}[:@var{port}][/@var{app}][/@var{playpath}]
-@end example
-
-The accepted parameters are:
-@table @option
-
-@item server
-The address of the RTMP server.
-
-@item port
-The number of the TCP port to use (by default is 1935).
-
-@item app
-It is the name of the application to access. It usually corresponds to
-the path where the application is installed on the RTMP server
-(e.g. @file{/ondemand/}, @file{/flash/live/}, etc.).
-
-@item playpath
-It is the path or name of the resource to play with reference to the
-application specified in @var{app}, may be prefixed by "mp4:".
-
-@end table
-
-For example to read with @file{ffplay} a multimedia resource named
-"sample" from the application "vod" from an RTMP server "myserver":
-@example
-ffplay rtmp://myserver/vod/sample
-@end example
-
-@section rtmp, rtmpe, rtmps, rtmpt, rtmpte
-
-Real-Time Messaging Protocol and its variants supported through
-librtmp.
-
-Requires the presence of the librtmp headers and library during
-configuration. You need to explicitely configure the build with
-"--enable-librtmp". If enabled this will replace the native RTMP
-protocol.
-
-This protocol provides most client functions and a few server
-functions needed to support RTMP, RTMP tunneled in HTTP (RTMPT),
-encrypted RTMP (RTMPE), RTMP over SSL/TLS (RTMPS) and tunneled
-variants of these encrypted types (RTMPTE, RTMPTS).
-
-The required syntax is:
-@example
-@var{rtmp_proto}://@var{server}[:@var{port}][/@var{app}][/@var{playpath}] @var{options}
-@end example
-
-where @var{rtmp_proto} is one of the strings "rtmp", "rtmpt", "rtmpe",
-"rtmps", "rtmpte", "rtmpts" corresponding to each RTMP variant, and
-@var{server}, @var{port}, @var{app} and @var{playpath} have the same
-meaning as specified for the RTMP native protocol.
-@var{options} contains a list of space-separated options of the form
-@var{key}=@var{val}.
-
-See the librtmp manual page (man 3 librtmp) for more information.
-
-For example, to stream a file in real-time to an RTMP server using
-@file{ffmpeg}:
-@example
-ffmpeg -re -i myfile -f flv rtmp://myserver/live/mystream
-@end example
-
-To play the same stream using @file{ffplay}:
-@example
-ffplay "rtmp://myserver/live/mystream live=1"
-@end example
-
-@section rtp
-
-Real-Time Protocol.
-
-@section rtsp
-
-RTSP is not technically a protocol handler in libavformat, it is a demuxer
-and muxer. The demuxer supports both normal RTSP (with data transferred
-over RTP; this is used by e.g. Apple and Microsoft) and Real-RTSP (with
-data transferred over RDT).
-
-The muxer can be used to send a stream using RTSP ANNOUNCE to a server
-supporting it (currently Darwin Streaming Server and Mischa Spiegelmock's
-@uref{http://github.com/revmischa/rtsp-server, RTSP server}).
-
-The required syntax for a RTSP url is:
-@example
-rtsp://@var{hostname}[:@var{port}]/@var{path}[?@var{options}]
-@end example
-
-@var{options} is a @code{&}-separated list. The following options
-are supported:
-
-@table @option
-
-@item udp
-Use UDP as lower transport protocol.
-
-@item tcp
-Use TCP (interleaving within the RTSP control channel) as lower
-transport protocol.
-
-@item multicast
-Use UDP multicast as lower transport protocol.
-
-@item http
-Use HTTP tunneling as lower transport protocol, which is useful for
-passing proxies.
-
-@item filter_src
-Accept packets only from negotiated peer address and port.
-@end table
-
-Multiple lower transport protocols may be specified, in that case they are
-tried one at a time (if the setup of one fails, the next one is tried).
-For the muxer, only the @code{tcp} and @code{udp} options are supported.
-
-When receiving data over UDP, the demuxer tries to reorder received packets
-(since they may arrive out of order, or packets may get lost totally). In
-order for this to be enabled, a maximum delay must be specified in the
-@code{max_delay} field of AVFormatContext.
-
-When watching multi-bitrate Real-RTSP streams with @file{ffplay}, the
-streams to display can be chosen with @code{-vst} @var{n} and
-@code{-ast} @var{n} for video and audio respectively, and can be switched
-on the fly by pressing @code{v} and @code{a}.
-
-Example command lines:
-
-To watch a stream over UDP, with a max reordering delay of 0.5 seconds:
-
-@example
-ffplay -max_delay 500000 rtsp://server/video.mp4?udp
-@end example
-
-To watch a stream tunneled over HTTP:
-
-@example
-ffplay rtsp://server/video.mp4?http
-@end example
-
-To send a stream in realtime to a RTSP server, for others to watch:
-
-@example
-ffmpeg -re -i @var{input} -f rtsp -muxdelay 0.1 rtsp://server/live.sdp
-@end example
-
-@section sap
-
-Session Announcement Protocol (RFC 2974). This is not technically a
-protocol handler in libavformat, it is a muxer and demuxer.
-It is used for signalling of RTP streams, by announcing the SDP for the
-streams regularly on a separate port.
-
-@subsection Muxer
-
-The syntax for a SAP url given to the muxer is:
-@example
-sap://@var{destination}[:@var{port}][?@var{options}]
-@end example
-
-The RTP packets are sent to @var{destination} on port @var{port},
-or to port 5004 if no port is specified.
-@var{options} is a @code{&}-separated list. The following options
-are supported:
-
-@table @option
-
-@item announce_addr=@var{address}
-Specify the destination IP address for sending the announcements to.
-If omitted, the announcements are sent to the commonly used SAP
-announcement multicast address 224.2.127.254 (sap.mcast.net), or
-ff0e::2:7ffe if @var{destination} is an IPv6 address.
-
-@item announce_port=@var{port}
-Specify the port to send the announcements on, defaults to
-9875 if not specified.
-
-@item ttl=@var{ttl}
-Specify the time to live value for the announcements and RTP packets,
-defaults to 255.
-
-@item same_port=@var{0|1}
-If set to 1, send all RTP streams on the same port pair. If zero (the
-default), all streams are sent on unique ports, with each stream on a
-port 2 numbers higher than the previous.
-VLC/Live555 requires this to be set to 1, to be able to receive the stream.
-The RTP stack in libavformat for receiving requires all streams to be sent
-on unique ports.
-@end table
-
-Example command lines follow.
-
-To broadcast a stream on the local subnet, for watching in VLC:
-
-@example
-ffmpeg -re -i @var{input} -f sap sap://224.0.0.255?same_port=1
-@end example
-
-Similarly, for watching in ffplay:
-
-@example
-ffmpeg -re -i @var{input} -f sap sap://224.0.0.255
-@end example
-
-And for watching in ffplay, over IPv6:
-
-@example
-ffmpeg -re -i @var{input} -f sap sap://[ff0e::1:2:3:4]
-@end example
-
-@subsection Demuxer
-
-The syntax for a SAP url given to the demuxer is:
-@example
-sap://[@var{address}][:@var{port}]
-@end example
-
-@var{address} is the multicast address to listen for announcements on,
-if omitted, the default 224.2.127.254 (sap.mcast.net) is used. @var{port}
-is the port that is listened on, 9875 if omitted.
-
-The demuxers listens for announcements on the given address and port.
-Once an announcement is received, it tries to receive that particular stream.
-
-Example command lines follow.
-
-To play back the first stream announced on the normal SAP multicast address:
-
-@example
-ffplay sap://
-@end example
-
-To play back the first stream announced on one the default IPv6 SAP multicast address:
-
-@example
-ffplay sap://[ff0e::2:7ffe]
-@end example
-
-@section tcp
-
-Trasmission Control Protocol.
-
-The required syntax for a TCP url is:
-@example
-tcp://@var{hostname}:@var{port}[?@var{options}]
-@end example
-
-@table @option
-
-@item listen
-Listen for an incoming connection
-
-@example
-ffmpeg -i @var{input} -f @var{format} tcp://@var{hostname}:@var{port}?listen
-ffplay tcp://@var{hostname}:@var{port}
-@end example
-
-@end table
-
-@section udp
-
-User Datagram Protocol.
-
-The required syntax for a UDP url is:
-@example
-udp://@var{hostname}:@var{port}[?@var{options}]
-@end example
-
-@var{options} contains a list of &-seperated options of the form @var{key}=@var{val}.
-Follow the list of supported options.
-
-@table @option
-
-@item buffer_size=@var{size}
-set the UDP buffer size in bytes
-
-@item localport=@var{port}
-override the local UDP port to bind with
-
-@item pkt_size=@var{size}
-set the size in bytes of UDP packets
-
-@item reuse=@var{1|0}
-explicitly allow or disallow reusing UDP sockets
-
-@item ttl=@var{ttl}
-set the time to live value (for multicast only)
-
-@item connect=@var{1|0}
-Initialize the UDP socket with @code{connect()}. In this case, the
-destination address can't be changed with ff_udp_set_remote_url later.
-If the destination address isn't known at the start, this option can
-be specified in ff_udp_set_remote_url, too.
-This allows finding out the source address for the packets with getsockname,
-and makes writes return with AVERROR(ECONNREFUSED) if "destination
-unreachable" is received.
-For receiving, this gives the benefit of only receiving packets from
-the specified peer address/port.
-@end table
-
-Some usage examples of the udp protocol with @file{ffmpeg} follow.
-
-To stream over UDP to a remote endpoint:
-@example
-ffmpeg -i @var{input} -f @var{format} udp://@var{hostname}:@var{port}
-@end example
-
-To stream in mpegts format over UDP using 188 sized UDP packets, using a large input buffer:
-@example
-ffmpeg -i @var{input} -f mpegts udp://@var{hostname}:@var{port}?pkt_size=188&buffer_size=65535
-@end example
-
-To receive over UDP from a remote endpoint:
-@example
-ffmpeg -i udp://[@var{multicast-address}]:@var{port}

-A Quick Description Of Rate Distortion Theory.
-
-We want to encode a video, picture or piece of music optimally. What does
-"optimally" really mean? It means that we want to get the best quality at a
-given filesize OR we want to get the smallest filesize at a given quality
-(in practice, these 2 goals are usually the same).
-
-Solving this directly is not practical; trying all byte sequences 1
-megabyte in length and selecting the "best looking" sequence will yield
-256^1000000 cases to try.
-
-But first, a word about quality, which is also called distortion.
-Distortion can be quantified by almost any quality measurement one chooses.
-Commonly, the sum of squared differences is used but more complex methods
-that consider psychovisual effects can be used as well. It makes no
-difference in this discussion.
-
-
-First step: that rate distortion factor called lambda...
-Let's consider the problem of minimizing:
-
-  distortion + lambda*rate
-
-rate is the filesize
-distortion is the quality
-lambda is a fixed value choosen as a tradeoff between quality and filesize
-Is this equivalent to finding the best quality for a given max
-filesize? The answer is yes. For each filesize limit there is some lambda
-factor for which minimizing above will get you the best quality (using your
-chosen quality measurement) at the desired (or lower) filesize.
-
-
-Second step: splitting the problem.
-Directly splitting the problem of finding the best quality at a given
-filesize is hard because we do not know how many bits from the total
-filesize should be allocated to each of the subproblems. But the formula
-from above:
-
-  distortion + lambda*rate
-
-can be trivially split. Consider:
-
-  (distortion0 + distortion1) + lambda*(rate0 + rate1)
-
-This creates a problem made of 2 independent subproblems. The subproblems
-might be 2 16x16 macroblocks in a frame of 32x16 size. To minimize:
-
-  (distortion0 + distortion1) + lambda*(rate0 + rate1)
-
-we just have to minimize:
-
-  distortion0 + lambda*rate0
-
-and
-
-  distortion1 + lambda*rate1
-
-I.e, the 2 problems can be solved independently.

-=============================================
-
-Introduction:

-This specification describes the Snow bitstream syntax and semantics as
-well as the formal Snow decoding process.
-
-The decoding process is described precisely and any compliant decoder
-MUST produce the exact same output for a spec-conformant Snow stream.
-For encoding, though, any process which generates a stream compliant to
-the syntactical and semantic requirements and which is decodable by
-the process described in this spec shall be considered a conformant
-Snow encoder.
-
-Definitions:
-============
-
-MUST    the specific part must be done to conform to this standard
-SHOULD  it is recommended to be done that way, but not strictly required
-

-    the sign of the coefficients is not explicitly stored but alternates
-    after each coeff and coeff[0] is positive, so ...,+,-,+,-,+,+,-,+,-,+,...
-    hcoeff[0] is not explicitly stored but found by subtracting the sum
-    of all stored coefficients with signs from 32
-    hcoeff[0]= 32 - hcoeff[1] - hcoeff[2] - ...
-    a good choice for hcoeff and htaps is
-    htaps= 6
-    hcoeff={40,-10,2}
-    an alternative which requires more computations at both encoder and

-Range Coding of integers:
--------------------------
-FIXME
-
-
-Neighboring Blocks:
-===================
-left and top are set to the respective blocks unless they are outside of
-the image in which case they are set to the Null block
-
-top-left is set to the top left block unless it is outside of the image in
-which case it is set to the left block
-
-if this block has no larger parent block or it is at the left side of its
-parent block and the top right block is not outside of the image then the
-top right block is used for top-right else the top-left block is used
-
-Null block
-y,cb,cr are 128
-level, ref, mx and my are 0
-
-
-Motion Vector Prediction:
-=========================
-1. the motion vectors of all the neighboring blocks are scaled to
-compensate for the difference of reference frames
-
-scaled_mv= (mv * (256 * (current_reference+1) / (mv.reference+1)) + 128)>>8
-
-2. the median of the scaled left, top and top-right vectors is used as
-motion vector prediction
-
-3. the used motion vector is the sum of the predictor and
-   (mvx_diff, mvy_diff)*mv_scale
-
-
-Intra DC Predicton:
-======================
-the luma and chroma values of the left block are used as predictors
-
-the used luma and chroma is the sum of the predictor and y_diff, cb_diff, cr_diff
-to reverse this in the decoder apply the following:
-block[y][x].dc[0] = block[y][x-1].dc[0] +  y_diff;
-block[y][x].dc[1] = block[y][x-1].dc[1] + cb_diff;
-block[y][x].dc[2] = block[y][x-1].dc[2] + cr_diff;
-block[*][-1].dc[*]= 128;

-Motion Compensation:

-Halfpel interpolation:
-----------------------
-halfpel interpolation is done by convolution with the halfpel filter stored
-in the header:
-
-horizontal halfpel samples are found by
-H1[y][x] =    hcoeff[0]*(F[y][x  ] + F[y][x+1])
-            + hcoeff[1]*(F[y][x-1] + F[y][x+2])

-            + ...
-h1[y][x] = (H1[y][x] + 32)>>6;
-
-vertical halfpel samples are found by
-H2[y][x] =    hcoeff[0]*(F[y  ][x] + F[y+1][x])
-            + hcoeff[1]*(F[y-1][x] + F[y+2][x])
-            + ...
-h2[y][x] = (H2[y][x] + 32)>>6;
-
-vertical+horizontal halfpel samples are found by
-H3[y][x] =    hcoeff[0]*(H2[y][x  ] + H2[y][x+1])
-            + hcoeff[1]*(H2[y][x-1] + H2[y][x+2])
-            + ...
-H3[y][x] =    hcoeff[0]*(H1[y  ][x] + H1[y+1][x])
-            + hcoeff[1]*(H1[y+1][x] + H1[y+2][x])

-===================
-Each sample in the LL0 subband is predicted by the median of the left, top and

-Wavelet Transform:
-==================
-
-Snow supports 2 wavelet transforms, the symmetric biorthogonal 5/3 integer
-transform and a integer approximation of the symmetric biorthogonal 9/7
-daubechies wavelet.
-
-2D IDWT (inverse discrete wavelet transform)
---------------------------------------------
-The 2D IDWT applies a 2D filter recursively, each time combining the
-4 lowest frequency subbands into a single subband until only 1 subband
-remains.
-The 2D filter is done by first applying a 1D filter in the vertical direction
-and then applying it in the horizontal one.

-TODO:
-=====
-Important:
-finetune initial contexts
-flip wavelet?
-try to use the wavelet transformed predicted image (motion compensated image) as context for coding the residual coefficients
-try the MV length as context for coding the residual coefficients
-use extradata for stuff which is in the keyframes now?
-the MV median predictor is patented IIRC
-implement per picture halfpel interpolation
-try different range coder state transition tables for different contexts
-
-Not Important:
-compare the 6 tap and 8 tap hpel filters (psnr/bitrate and subjective quality)
-spatial_scalability b vs u (!= 0 breaks syntax anyway so we can add a u later)

-Google Summer of Code and similar project guidelines
-
-Summer of Code is a project by Google in which students are paid to implement
-some nice new features for various participating open source projects ...
-
-This text is a collection of things to take care of for the next soc as
-it's a little late for this year's soc (2006).
-
-The Goal:
-Our goal in respect to soc is and must be of course exactly one thing and
-that is to improve FFmpeg, to reach this goal, code must
-* conform to the development policy and patch submission guidelines
-* must improve FFmpeg somehow (faster, smaller, "better",
-  more codecs supported, fewer bugs, cleaner, ...)
-
-for mentors and other developers to help students to reach that goal it is
-essential that changes to their codebase are publicly visible, clean and
-easy reviewable that again leads us to:
-* use of a revision control system like git
-* separation of cosmetic from non-cosmetic changes (this is almost entirely
-  ignored by mentors and students in soc 2006 which might lead to a suprise
-  when the code will be reviewed at the end before a possible inclusion in
-  FFmpeg, individual changes were generally not reviewable due to cosmetics).
-* frequent commits, so that comments can be provided early

-
-
-Swscale has 2 scaler paths. Each side must be capable of handling
-slices, that is, consecutive non-overlapping rectangles of dimension
-(0,slice_top) - (picture_width, slice_bottom).
-
-special converter
-    These generally are unscaled converters of common
-    formats, like YUV 4:2:0/4:2:2 -> RGB12/15/16/24/32. Though it could also
-    in principle contain scalers optimized for specific common cases.
-
-Main path
-    The main path is used when no special converter can be used. The code
-    is designed as a destination line pull architecture. That is, for each
-    output line the vertical scaler pulls lines from a ring buffer. When
-    the ring buffer does not contain the wanted line, then it is pulled from
-    the input slice through the input converter and horizontal scaler.
-    The result is also stored in the ring buffer to serve future vertical
-    scaler requests.
-    When no more output can be generated because lines from a future slice
-    would be needed, then all remaining lines in the current slice are
-    converted, horizontally scaled and put in the ring buffer.
-    [This is done for luma and chroma, each with possibly different numbers
-     of lines per picture.]
-
-Input to YUV Converter
-    When the input to the main path is not planar 8 bits per component YUV or
-    8-bit gray, it is converted to planar 8-bit YUV. Two sets of converters
-    exist for this currently: One performs horizontal downscaling by 2
-    before the conversion, the other leaves the full chroma resolution,
-    but is slightly slower. The scaler will try to preserve full chroma
-    when the output uses it. It is possible to force full chroma with
-    SWS_FULL_CHR_H_INP even for cases where the scaler thinks it is useless.
-
-Horizontal scaler
-    There are several horizontal scalers. A special case worth mentioning is
-    the fast bilinear scaler that is made of runtime-generated MMX2 code
-    using specially tuned pshufw instructions.
-    The remaining scalers are specially-tuned for various filter lengths.
-    They scale 8-bit unsigned planar data to 16-bit signed planar data.
-    Future >8 bits per component inputs will need to add a new horizontal
-    scaler that preserves the input precision.
-
-Vertical scaler and output converter
-    There is a large number of combined vertical scalers + output converters.
-    Some are:
-    * unscaled output converters
-    * unscaled output converters that average 2 chroma lines
-    * bilinear converters                (C, MMX and accurate MMX)
-    * arbitrary filter length converters (C, MMX and accurate MMX)
-    And
-    * Plain C  8-bit 4:2:2 YUV -> RGB converters using LUTs
-    * Plain C 17-bit 4:4:4 YUV -> RGB converters using multiplies
-    * MMX     11-bit 4:2:2 YUV -> RGB converters
-    * Plain C 16-bit Y -> 16-bit gray
-      ...
-
-    RGB with less than 8 bits per component uses dither to improve the
-    subjective quality and low-frequency accuracy.
-
-
-Filter coefficients:
---------------------
-There are several different scalers (bilinear, bicubic, lanczos, area,
-sinc, ...). Their coefficients are calculated in initFilter().
-Horizontal filter coefficients have a 1.0 point at 1 << 14, vertical ones at
-1 << 12. The 1.0 points have been chosen to maximize precision while leaving
-a little headroom for convolutional filters like sharpening filters and
-minimizing SIMD instructions needed to apply them.
-It would be trivial to use a different 1.0 point if some specific scaler
-would benefit from it.
-Also, as already hinted at, initFilter() accepts an optional convolutional
-filter as input that can be used for contrast, saturation, blur, sharpening
-shift, chroma vs. luma shift, ...

-Writing a table generator
-
-This documentation is preliminary.
-Parts of the API are not good and should be changed.
-
-Basic concepts
-
-A table generator consists of two files, *_tablegen.c and *_tablegen.h.
-The .h file will provide the variable declarations and initialization
-code for the tables, the .c calls the initialization code and then prints
-the tables as a header file using the tableprint.h helpers.
-Both of these files will be compiled for the host system, so to avoid
-breakage with cross-compilation neither of them may include, directly
-or indirectly, config.h or avconfig.h.
-This means that e.g. libavutil/mathematics.h is ok but libavutil/libm.h is not.
-Due to this, the .c file or Makefile may have to provide additional defines
-or stubs, though if possible this should be avoided.
-In particular, CONFIG_HARDCODED_TABLES should always be defined to 0.
-
-The .c file
-
-This file should include the *_tablegen.h and tableprint.h files and
-anything else it needs as long as it does not depend on config.h or
-avconfig.h.
-In addition to that it must contain a main() function which initializes
-all tables by calling the init functions from the .h file and then prints
-them.
-The printing code typically looks like this:
-    write_fileheader();
-    printf("static const uint8_t my_array[100] = {\n");
-    write_uint8_t_array(my_array, 100);
-    printf("};\n");
-
-This is the more generic form, in case you need to do something special.
-Usually you should instead use the short form:
-    write_fileheader();
-    WRITE_ARRAY("static const", uint8_t, my_array);
-
-write_fileheader() adds some minor things like a "this is a generated file"
-comment and some standard includes.
-tablegen.h defines some write functions for one- and two-dimensional arrays
-for standard types - they print only the "core" parts so they are easier
-to reuse for multi-dimensional arrays so the outermost {} must be printed
-separately.
-If there's no standard function for printing the type you need, the
-WRITE_1D_FUNC_ARGV macro is a very quick way to create one.
-See libavcodec/dv_tablegen.c for an example.
-
-
-The .h file
-
-This file should contain:
- - one or more initialization functions
- - the table variable declarations
-If CONFIG_HARDCODED_TABLES is set, the initialization functions should
-not do anything, and instead of the variable declarations the
-generated *_tables.h file should be included.
-Since that will be generated in the build directory, the path must be
-included, i.e.
-#include "libavcodec/example_tables.h"
-not
-#include "example_tables.h"
-
-Makefile changes
-
-To make the automatic table creation work, you must manually declare the
-new dependency.
-For this add a line similar to this:
-$(SUBDIR)example.o: $(SUBDIR)example_tables.h
-under the "ifdef CONFIG_HARDCODED_TABLES" section in the Makefile.

-This is a quick description of the viterbi aka dynamic programing
-algorthm.
-
-Its reason for existence is that wikipedia has become very poor on
-describing algorithms in a way that makes it useable for understanding
-them or anything else actually. It tends now to describe the very same
-algorithm under 50 different names and pages with few understandable
-by even people who fully understand the algorithm and the theory behind.
-
-Problem description: (that is what it can solve)
-assume we have a 2d table, or you could call it a graph or matrix if you
-prefer
-
-    O   O   O   O   O   O   O
-
-    O   O   O   O   O   O   O
-
-    O   O   O   O   O   O   O
-
-    O   O   O   O   O   O   O
-
-
-That table has edges connecting points from each column to the next column
-and each edge has a score like: (only some edge and scores shown to keep it
-readable)
-
-
-    O--5--O-----O-----O-----O-----O
-     2   / 7   / \   / \   / \   /
-      \ /   \ /   \ /   \ /   \ /
-    O7-/--O--/--O--/--O--/--O--/--O
-     \/ \/ 1/ \/ \/ \/ \/ \/ \/ \/
-     /\ /\ 2\ /\ /\ /\ /\ /\ /\ /\
-    O3-/--O--/--O--/--O--/--O--/--O
-      / \   / \   / \   / \   / \
-     1   \ 9   \ /   \ /   \ /   \
-    O--2--O--1--O--5--O--3--O--8--O
-
-
-
-Our goal is to find a path from left to right through it which
-minimizes the sum of the score of all edges.
-(and of course left/right is just a convention here it could be top down too)
-Similarly the minimum could be the maximum by just fliping the sign,
-Example of a path with scores:
-
-    O   O   O   O   O   O   O
-
->---O.  O   O  .O-2-O   O   O
-      5.     .7      .
-    O   O-1-O   O   O 8 O   O
-                       .
-    O   O   O   O   O   O-1-O---> (sum here is 24)
-
-
-The viterbi algorthm now solves this simply column by column
-For the previous column each point has a best path and a associated
-score:
-
-    O-----5     O
-     \
-      \
-    O  \  1     O
-        \/
-        /\
-    O  /  2     O
-      /
-     /
-    O-----2     O
-
-
-To move one column forward we just need to find the best path and associated
-scores for the next column
-here are some edges we could choose from:
-
-
-    O-----5--3--O
-     \      \8
-      \       \
-    O  \  1--9--O
-        \/  \3
-        /\     \
-    O  /  2--1--O
-      /     \2
-     /        \
-    O-----2--4--O
-
-Finding the new best pathes and scores for each point of our new column is
-trivial given we know the previous column best pathes and scores:
-
-    O-----0-----8
-     \
-      \
-    O  \  0----10
-        \/
-        /\
-    O  /  0-----3
-      /     \
-     /        \
-    O     0     4
-
-
-the viterbi algorthm continues exactly like this column for column until the
-end and then just picks the path with the best score (above that would be the
-one with score 3)
