Andreas Rheinhardt d91b3a16b5 swscale/x86/yuv2rgb_template: Add emms to MMX(EXT) functions
Fixes issue #22333.
Note: These functions have been removed in commit
61e851381f, so the issue
only affects releases 7.0 and older.

Lynne 0ef8ce13b8 aacenc_tns: clamp filter direction energy measurement
The issue is that:

float en[2];
...
tns->n_filt[w] = is8 ? 1 : order != TNS_MAX_ORDER ? 2 : 3;
for (g = 0; g < tns->n_filt[w]; g++) {
    tns->direction[w][g] = slant != 2 ? slant : en[g] < en[!g];

When using the AAC Main profile, n_filt = 3, and slant is by
default 2 (normal long frames), g can go above 1.

en is the evolution of energy in the frequency domain for every
band at the given window. E.g. whether the energy is concentrated
at the top of each band, or the bottom.

For 2-pole filters, its straightforward.
For 3-pole filters, we need more than 2 measurements.

This commit properly implements support for 3-pole filters, by measuring
the band energy across three areas.

Do note that even xHE-AAC caps n_filt to 2, and only AAC Main allows
n_filt == 3.

Haihao Xiang 2d32a6611a lavc/vp9: Fix regression introduced in 0ba05857
It is possible that ff_progress_frame_await() is called but
ff_progress_frame_report() isn't called when a hardware acceleration
method is used, so a thread for vp9 decoding might get stuck.

Backport comment: in 7.1 there was a switch to ProgressFrames
(7bd3b73716), so there was the need to convert the calls back to
ThreadFrames calls. In this case, it was just moving the progress
report function inside the finish label.

Andreas Rheinhardt 415ed8bb09 avcodec/vp9: Fix race when attaching side-data for show-existing frame
When outputting a show-existing frame, the VP9 decoder simply
created a reference to said frame and returned it immediately to
the caller, without waiting for it to have finished decoding.
In case of frame-threading it is possible for the frame to
only be decoded while it was waiting to be output.
This is normally benign.

But there is one case where it is not: If the user wants
video encoding parameters to be exported, said side data
will only be attached to the src AVFrame at the end of
decoding the frame that is actually being shown. Without
synchronisation adding said side data in the decoder thread
and the reads in av_frame_ref() in the output thread
constitute a data race. This happens e.g. when using the
venc_data_dump tool with vp90-2-10-show-existing-frame.webm
from the FATE-suite.

Fix this by actually waiting for the frame to be output.

Backport comment: in 7.1 there was a switch to ProgressFrames
(7bd3b73716), so there was the need to convert the calls back to
ThreadFrames calls.

softworkz 69a6974116 avformat/hls: Partially revert "reduce default max reload to 3"
(setting to 100 as a reasonable compromise)

The change has caused regressions for many users and consumers.
Playlist reloads only happen when a playlist doesn't indicate that it
has ended (via #EXT-X-ENDLIST), which means that the addition of future
segments is still expected.
It is well possible that an HLS server is temporarily unable to serve
further segments but resumes after some time, either indicating a
discontinuity or even by fully catching up.
With a segment length of 3s, a max_reload value of 1000 corresponds to
a duration of 50 minutes which appears to be a reasonable default.

Cosmin Stejerean 23afb77b8e avfilter/bwdif: account for chroma sub-sampling in min size calculation
The current logic for detecting frames that are too small for the
algorithm does not account for chroma sub-sampling, and so a sample
where the luma plane is large enough, but the chroma planes are not
will not be rejected. In that event, a heap overflow will occur.

This change adjusts the logic to consider the chroma planes and makes
the change to all three bwdif implementations.

Janne Grunau 6cd0bdf3b0 vp9: recon: Use emulated edge to prevent buffer overflows
The arm/aarch64 horizontal filter reads one additional pixel beyond what
the filter uses. This can become an issue if the application does not
allocate larger buffers than what's required for the pixel data. If the
motion vector points to the bottom right edge of the picture this
becomes a read buffer overflow. This triggers segfaults in Firefox for
video resolutions which result in a page aligned picture size like
1280x640.
Prevent this by using emulated edge in this case.

Janne Grunau 131bd9436c arm: vp9mc: Load only 12 pixels in the 4 pixel wide horizontal filter
This reduces the amount the horizontal filters read beyond the filter
width to a consistent 1 pixel. The data is not used so this is usually
not noticeable. It becomes a problem when the application allocates
frame buffers only for the aligned picture size and the end of it is at
a page boundary. This happens for picture sizes which are a multiple of
the page size like 1280x640. The frame buffer allocation is based on
its most likely done via mmap + MAP_ANONYMOUS so start and end of the
buffer are page aligned and the previous and next page are not
necessarily mapped.
This mirrors the aarch64 change.

necessarily mapped.
Under these conditions like seen by Firefox a read beyond the end of the
buffer results in a segfault.
After the over-read is reduced to a single pixel it's reasonable to use
VP9's emulated edge motion compensation for this.

Michael Niedermayer 09f16093e6 avcodec/utils: apply the same alignment to YUV410 as we do to YUV420 for snow
The snow encoder uses block based motion estimation which can read out of array if
insufficient alignment is used

It may be better to only apply this for the encoder, as it would safe a few bytes of memory
for the decoder. Until then, this fixes the issue in a simple way.

Michael Niedermayer 747a3f6999 avformat/rtsp: initialize reply1
It seems reply1 is initialized by ff_rtsp_send_cmd() in most cases but there
are code paths like "continue" which look like they could skip it but even if not
writing this so a complex loop after several layers of calls initialized a local
variable through a pointer is just bad design.
This patch simply initialized the variable.

Mark Thompson 93c16626b5 cbs_av1: Reject thirty-two zero bits in uvlc code
The spec allows at least thirty-two zero bits followed by a one to mean
2^32-1, with no constraint on the number of zeroes.  The libaom
reference decoder does not match this, instead reading thirty-two zeroes
but not the following one to mean 2^32-1.  These two interpretations are
incompatible and other implementations may follow one or the other.
Therefore reject thirty-two zeroes because the intended behaviour is not
clear.

Romain Beauxis 294ec29bde libavformat/hlsenc.c: Populate OTI using AAC profile in write_codec_attr.
This patch populates the third entry for HLS codec attribute using the
AAC profile.

The HLS specifications[1] require this value to be the Object Type ID as
referred to in table 1.3 of ISO/IEC 14496-3:2009[2].

The numerical constants in the code refer to these OTIs minus one, as
documented in commit 372597e[3], confirmed by comparing the values in the
code with the values in the table mentioned above.

Martin Storsjö bd7a10a2a8 seek: Fix crashes in ff_seek_frame_binary if built with latest Clang 14
Passing an uninitialized variable as argument to a function is
undefined behaviour (UB). The compiler can assume that UB does not
happen.

Hence, the compiler can assume that the variables are never
uninitialized when passed as argument, which means that the codepaths
that initializes them must be taken.

In ff_seek_frame_binary, this means that the compiler can assume
that the codepaths that initialize pos_min and pos_max are taken,
which means that the conditions "if (sti->index_entries)" and
"if (index >= 0)" can be optimized out.

Current Clang git versions (upcoming Clang 14) enabled an optimization
that does this, which broke the current version of this function
(which intentionally left the variables uninitialized, but silencing
warnings about being uninitialized). See [1] for discussion on
the matter.

Frank Plowman d6b9852317 doc/html: fix styling issue with Texinfo 7.0
Texinfo 7.0 produces quite different HTML to Texinfo 6.8. Without
this change, enumerated option flags (i.e. Possible values of x
are...) render as white text on a white background with Texinfo 7.0
and are unreadable. This change removes a style for the selector
`.table .table` which causes the background to turn white for these
elements. As far as I can tell, it is not actually used anywhere in
files generated by Texinfo 6.8.

Frank Plowman 6a9e2b4cda doc/html: support texinfo 7.0
Resolves trac ticket #10636 (http://trac.ffmpeg.org/ticket/10636).

Texinfo 7.0, released in November 2022, changed the names of various
functions. Compiling docs with Texinfo 7.0 resulted in warnings and
improperly formatted documentation. More old names appear to have
been removed in Texinfo 7.1, released October 2023, which causes docs
compilation to fail.

This commit addresses the issue by adding logic to switch between the old
and new function names depending on the Texinfo version. Texinfo 6.8
produces identical documentation before and after the patch.

texinfo commit 41f8ed4eb42bf6daa7df7007afd946875597452d replaced
OUTPUT_CONTENTS_LOCATION with CONTENTS_OUTPUT_LOCATION.

With texinfo 6.8 and above, the same as INLINE_CONTENTS=1 could be
achieved by CONTENTS_OUTPUT_LOCATION=inline.

Michael Niedermayer 0318ed865b avformat/hls: reduce default max reload to 3
The 1000 did result in the appearance of a never ending reload loop

The RFC mandates that "If the client reloads a Playlist file and finds that it has not
changed, then it MUST wait for a period of one-half the target
duration before retrying." and if it has changed
"the client MUST wait for at least the target duration before attempting to reload the
Playlist file again"

Trying to reload 3 times seems a better default than 1000 given these
durations

NOTICE for Package Maintainers
------------------------------
- It is recommended to build FFmpeg twice, first with minimal external dependencies so
that 3rd party packages, which depend on FFmpegs libavutil/libavfilter/libavcodec/libavformat
can then be built. And last build FFmpeg with full dependancies (which may in turn depend on
some of these 3rd party packages). This avoids circular dependencies during build.
