+This encoder is of much lower quality and is more unstable than any other AAC
+encoders, so it's highly recommended to instead use other encoders, like
+@ref{aacenc,,the native FFmpeg AAC encoder}.
+
+This encoder also requires the presence of the libfaac headers and library

+
+Only relevant when VBR mode is enabled with @code{flags +qscale}.  The
+value is converted to QP units by dividing it by @code{FF_QP2LAMBDA},
+and used to set the quality value used by libfaac. A reasonable range
+for the option value in QP units is [10-500], the higher the value the
+higher the quality.

+Enable VBR mode when set to a non-negative value, and set constant

-CONTEXT
-=======
-
-The FFmpeg project merges all the changes from the Libav project
-(https://libav.org) since the origin of the fork (around 2011).
-
-With the exceptions of some commits due to technical/political disagreements or
-issues, the changes are merged on a more or less regular schedule (daily for
-years thanks to Michael, but more sparse nowadays).
-
-WHY
-===
-
-The majority of the active developers believe the project needs to keep this
-policy for various reasons.
-
-The most important one is that we don't want our users to have to choose
-between two distributors of libraries of the exact same name in order to have a
-different set of features and bugfixes. By taking the responsibility of
-unifying the two codebases, we allow users to benefit from the changes from the
-two teams.
-
-Today, FFmpeg has a much larger user database (we are distributed by every
-major distribution), so we consider this mission a priority.
-
-A different approach to the merge could have been to pick the changes we are
-interested in and drop most of the cosmetics and other less important changes.
-Unfortunately, this makes the following picks much harder, especially since the
-Libav project is involved in various deep API changes. As a result, we decide
-to virtually take everything done there.
-
-Any Libav developer is of course welcome anytime to contribute directly to the
-FFmpeg tree. Of course, we fully understand and are forced to accept that very
-few Libav developers are interested in doing so, but we still want to recognize
-their work. This leads us to create merge commits for every single one from
-Libav. The original commit appears totally unchanged with full authorship in
-our history (and the conflict are solved in the merge one). That way, not a
-single thing from Libav will be lost in the future in case some reunification
-happens, or that project disappears one way or another.
-
-DOWNSIDES
-=========
-
-Of course, there are many downsides to this approach.
-
-- It causes a non negligible merge commits pollution. We make sure there are
-  not several level of merges entangled (we do a 1:1 merge/commit), but it's
-  still a non-linear history.
-
-- Many duplicated work. For instance, we added libavresample in our tree to
-  keep compatibility with Libav when our libswresample was already covering the
-  exact same purpose. The same thing happened for various elements such as the
-  ProRes support (but differences in features, bugs, licenses, ...). There are
-  many work to do to unify them, and any help is very much welcome.
-
-- So much manpower from both FFmpeg and Libav is lost because of this mess. We
-  know it, and we don't know how to fix it. It takes incredible time to do
-  these merges, so we have even less time to work on things we personally care
-  about. The bad vibes also do not help with keeping our developers motivated.
-
-- There is a growing technical risk factor with the merges due to the codebase
-  differing more and more.
-
-MERGE GUIDELINES
-================
-
-The following gives developer guidelines on how to proceed when merging Libav commits.
-
-Before starting, you can reduce the risk of errors on merge conflicts by using
-a different merge conflict style:
-
-    $ git config --global merge.conflictstyle diff3
-
-tools/libav-merge-next-commit is a script to help merging the next commit in
-the queue. It assumes a remote named libav. It has two modes: merge, and noop.
-The noop mode creates a merge with no change to the HEAD. You can pass a hash
-as extra argument to reference a justification (it is common that we already
-have the change done in FFmpeg).
-
-Also see tools/murge, you can copy and paste a 3 way conflict into its stdin
-and it will display colored diffs. Any arguments to murge (like ones to suppress
-whitespace differences) are passed into colordiff.
-
-TODO/FIXME/UNMERGED
-===================
-
-Stuff that didn't reach the codebase:
--------------------------------------
-
-- HEVC DSP and x86 MC SIMD improvements from Libav (see https://ffmpeg.org/pipermail/ffmpeg-devel/2015-December/184777.html)
-- QSV HWContext integration (04b17ff and 130e1f1), QSV scaling filter (62c58c5)
-
-Collateral damage that needs work locally:
-------------------------------------------
-
-- Merge proresdec2.c and proresdec_lgpl.c
-- Merge proresenc_anatoliy.c and proresenc_kostya.c
-- Remove ADVANCED_PARSER in libavcodec/hevc_parser.c
