 Release Notes
 =============
 
-* 0.6 "Works with HTML5" June, 2010
+* 0.5 "Bike Shed World Domination" March 3, 2009
 
 General notes
 -------------
 
-This release features a lot of improvements that are relevant for HTML5 video.
-The H.264 and Theora decoders are now significantly faster, the vorbis decoder
-has seen important updates and this release supports Google's newly released
-libvpx library for the VP8 codec and WEBM container.
-
-Other important changes are additions of decoders including, but not limited to,
-Intel Indeo 5, WMA Pro, WMA Voice and HE-AAC.
+It has been so long since the last release that this should be considered the
+first FFmpeg release of recent times. Because of the way things have unfolded to
+date, the notes for this version cannot be entirely conventional.
 
 See the Changelog file for a list of significant changes.

+API notes
+---------
 
-API and other notable Changes
------------------------------
+In the next release, it is intended to remove a number of deprecated APIs. We
+decided to put out a release that includes said APIs for the benefit of third
+party software.
 
-Please see the file doc/APIchanges for programmer-centric information.
+As such, this release:
+- provides a sync point for said APIs
+- increases awareness of API changes
+- allows the next release to detail how to transition from the old to the new
 
-Notable changes:
-- deprecated vhook subsystem removed
-- deprecated old scaler removed
-- nonfree libamr support for AMR-NB/WB decoding/encoding removed
-- RTMP support in libavformat
-- -formats option split into -formats, -codecs, -bsfs, and -protocols
-- ffprobe tool
-- RTMP/RTMPT/RTMPS/RTMPE/RTMPTE protocol support via librtmp
-- CODEC_CAP_EXPERIMENTAL added
+The deprecated APIs to be removed are:
+- imgconvert (to be replaced by libswscale)
+- vhook (to be replaced by libavfilter)
+
+If at all possible, do not use the deprecated APIs. All notes on API changes
+should appear in doc/APIchanges.
 
 
-Added Codecs:

+This point release includes some minor updates to make the 0.5 release series
+usable for users that need to retain the existing behavior as closely as
+possible. The changes follow below:
+
+Security fixes
+--------------
+
+Various programming errors in container and codec implementations
+may lead to denial of service or the execution of arbitrary code
+if the user is tricked into opening a malformed media file or stream.
+
+Affected and updated have been the implementations of the following
+codecs and container formats:
+
+ - the Vorbis audio codec
+ - the FF Video 1 codec
+ - the MPEG audio codec
+ - the H264 video codec
+ - the MLP codec
+ - the HuffYUV codec
+ - the ASF demuxer
+ - the Ogg container implementation
+ - the MOV container implementation
+
+Symbol Versioning enabled
+-------------------------
+
+The backported symbol versioning change is enabled on platforms that support
+it. This allows users to upgrade from 0.5.1 to the upcoming 0.6 release
+without having to recompile their applications. Please note that distributors
+have to recompile applications against 0.5.1 before upgrading to 0.6.
+
+libx264.c backport
+------------------
+
+This release includes a backport to the libx264 wrapper that allows FFmpeg to
+be compiled against newer versions of libx264 up to API version 85.
+
+licensing changes
+-----------------
+
+Previously both libswscale and our AC-3 decoder had GPLed parts. These have
+been replaced by fresh LGPL code. x86 optimizations for libswscale remain GPL,
+but the C code is fully functional. Optimizations for other architectures have
+been relicensed to LGPL.
+
+AMR-NB decoding/encoding and AMR-WB decoding is now possible through the free
+software OpenCORE libraries as an alternative to the non-free libamr libraries.
+
+We found out that libfaac contains non-free parts and is not LGPL as previously
+claimed. We have changed configure to reflect this. You now have to pass the
+--enable-nonfree option if you wish to compile with libfaac support enabled.
+
+Furthermore the non-free bits in libavcodec/fdctref.c have been rewritten. Note
+well that they were only used in a test program and never compiled into any
+FFmpeg library.
 
 
-Notable license related changes
--------------------------------
 
-- remaining GPL parts in AC-3 decoder converted to LGPL
-- libswscale can now be compiled in LGPL mode
-- libvpx is considered (L)GPL incompatible
+* 0.5.2 May 25, 2010
+
+General notes
+-------------
+
+This is a maintenance-only release that addresses a small number of security
+and portability issues. Distributors and system integrators are encouraged
+to update and share their patches against this branch.
+
+
+
+* 0.5.3 Oct 18, 2010
+
+General notes
+-------------
+
+This is (again) another maintenance-only release that addresses a fix
+for seekable HTTP and an exploitable bug in the FLIC decoder
+(cf. CVE-2010-3429 for details). Distributors and system integrators are
+encouraged to update and share their patches against this branch.
+
+
+
+* 0.5.4 Mar 17, 2011
+
+General notes
+-------------
+
+This is the first release that we cut after git migration. It is another
+maintenance-only release that addresses several security issues that were
+brought to our attention. In detail, fixes for RV30/40, WMV, Vorbis and
+VC-1 have been backported from trunk. Distributors and system integrators
+are encouraged to update and share their patches against this branch.
+
+
+
+* 0.5.5 Nov 6, 2011
+
+General notes
+-------------
+
+This maintenance-only release addresses several security issues that
+were brought to our attention. In detail, fixes for the MJPEG decoder,
+the CAVS decoder (CVE-2011-3362, CVE-2011-3973, CVE-2011-3974), and the
+Matroska decoder (MSVR11-011/CVE-2011-3504) and many others have been
+corrected. Additional, this release contains fixes for compilation with
+gcc-4.6. Distributors and system integrators are encouraged to update
+and share their patches against this branch.

-  The old decoding functions are deprecated, all new code should use the
-  new functions avcodec_decode_video2(), avcodec_decode_audio3() and

-  Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
-  PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
-  Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
-  PIX_FMT_BGR32_1 are now macros.

-@item libavcodec is the library containing the codecs (both encoding and
-decoding). Look at @file{libavcodec/apiexample.c} to see how to use it.

-audio or video streams.
-

-
-@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 GCC 2.95 and GCC 3.3. Currently, FFmpeg also
-compiles with several other compilers, such as the Compaq ccc compiler
-or Sun Studio 9, and we would like to keep it that way unless it would
-be exceedingly involved. To ensure compatibility, please do not use any
-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 Subversion 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.c
- * MPEG codec.
- * @@author ...
- */
-
-/**
- * Summary sentence.
- * more text ...
- * ...
- */
-typedef struct Foobar@{
-    int var1; /**< var1 description */
-    int var2; ///< var2 description
-    /** var3 description */
-    int var3;
-@} Foobar;
-
-/**
- * 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 program (renaming options etc) 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.
-@item
-   If you apply a patch by someone else, include the name and email address in
-   the log message. Since the ffmpeg-cvslog mailing list is publicly
-   archived you should add some SPAM protection to the email address. 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

-    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.

-@section Submitting patches
-
-First, (@pxref{Coding Rules}) above if you did not yet.
-
-When you submit your patch, try to send a unified diff (diff '-up'
-option). 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 regression tests before submitting a patch so that you can
-verify that there are no big 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.mplayerhq.hu/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 SVN.
-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].

-@chapter Introduction
-
-@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:''.

+generated by ./configure to understand what is needed.

+
+@node 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 GCC 2.95 and GCC 3.3. Currently, FFmpeg also
+compiles with several other compilers, such as the Compaq ccc compiler
+or Sun Studio 9, and we would like to keep it that way unless it would
+be exceedingly involved. To ensure compatibility, please do not use any
+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 the one specified 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 Subversion 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.c
+ * MPEG codec.
+ * @@author ...
+ */
+
+/**
+ * Summary sentence.

+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 program (renaming options etc) 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.
+@item
+   If you apply a patch by someone else, include the name and email address in
+   the log message. Since the ffmpeg-cvslog mailing list is publicly
+   archived you should add some SPAM protection to the email address. 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, (@pxref{Coding Rules}) above if you did not yet.
+
+When you submit your patch, try to send a unified diff (diff '-up'
+option). 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.
+
+Run the regression tests before submitting a patch so that you can
+verify that there are no big 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.mplayerhq.hu/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.

+    URL, you can upload to ftp://upload.ffmpeg.org
+@item
+    Did you provide a verbose summary about what the patch does change?
+@item
+    Did you provide a verbose explanation why it changes things like it does?
+@item
+    Did you provide a verbose summary of the user visible advantages and
+    disadvantages if the patch is applied?
+@item
+    Did you provide an example so we can verify the new feature added by the
+    patch easily?
+@item
+    If you added a new file, did you insert a license header? It should be
+    taken from FFmpeg, not randomly copied and pasted from somewhere else.
+@item
+    You should maintain alphabetical order in alphabetically ordered lists as
+    long as doing so does not break API/ABI compatibility.
+@item
+    Lines with similar content should be aligned vertically when doing so
+    improves readability.
+@item
+    Did you provide a suggestion for a clear commit log message?
+@end enumerate
+
+@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 SVN.
+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 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.
+
+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].

+@center @titlefont{Video Hook Documentation}
+@sp 3
+@end titlepage
+
+
+@chapter Introduction
+
+@var{Please be aware that vhook is deprecated, and hence its development is
+frozen (bug fixes are still accepted).
+The substitute will be 'libavfilter', the result of our 'Video Filter API'
+Google Summer of Code project. You may monitor its progress by subscribing to
+the ffmpeg-soc mailing list at
+@url{http://lists.mplayerhq.hu/mailman/listinfo/ffmpeg-soc}.}
+
+The video hook functionality is designed (mostly) for live video. It allows
+the video to be modified or examined between the decoder and the encoder.
+
+Any number of hook modules can be placed inline, and they are run in the
+order that they were specified on the ffmpeg command line.
+
+The video hook modules are provided for use as a base for your own modules,
+and are described below.
+
+Modules are loaded using the -vhook option to ffmpeg. The value of this parameter
+is a space separated list of arguments. The first is the module name, and the rest
+are passed as arguments to the Configure function of the module.
+
+The modules are dynamic libraries: They have different suffixes (.so, .dll, .dylib)
+depending on your platform. And your platform dictates if they need to be
+somewhere in your PATH, or in your LD_LIBRARY_PATH. Otherwise you will need to
+specify the full path of the vhook file that you are using.
+
+@section null.c
+
+This does nothing. Actually it converts the input image to RGB24 and then converts
+it back again. This is meant as a sample that you can use to test your setup.
+
+@section fish.c
+
+This implements a 'fish detector'. Essentially it converts the image into HSV
+space and tests whether more than a certain percentage of the pixels fall into
+a specific HSV cuboid. If so, then the image is saved into a file for processing
+by other bits of code.
+
+Why use HSV? It turns out that HSV cuboids represent a more compact range of
+colors than would an RGB cuboid.
+
+@section imlib2.c
+
+This module implements a text overlay for a video image. Currently it
+supports a fixed overlay or reading the text from a file. The string
+is passed through strftime() so that it is easy to imprint the date and
+time onto the image.
+
+This module depends on the external library imlib2, available on
+Sourceforge, among other places, if it is not already installed on
+your system.
+
+You may also overlay an image (even semi-transparent) like TV stations do.
+You may move either the text or the image around your video to create
+scrolling credits, for example.
+
+The font file used is looked for in a FONTPATH environment variable, and
+prepended to the point size as a command line option and can be specified
+with the full path to the font file, as in:
+@example
+-F /usr/X11R6/lib/X11/fonts/TTF/VeraBd.ttf/20
+@end example
+where 20 is the point size.
+
+You can specify the filename to read RGB color names from. If it is not
+specified, these defaults are used: @file{/usr/share/X11/rgb.txt} and
+@file{/usr/lib/X11/rgb.txt}
+
+Options:
+@multitable @columnfractions .2 .8
+@item @option{-C <rgb.txt>}   @tab The filename to read RGB color names from
+@item @option{-c <color>}     @tab The color of the text
+@item @option{-F <fontname>}  @tab The font face and size
+@item @option{-t <text>}      @tab The text
+@item @option{-f <filename>}  @tab The filename to read text from
+@item @option{-x <expression>}@tab x coordinate of text or image
+@item @option{-y <expression>}@tab y coordinate of text or image
+@item @option{-i <filename>}  @tab The filename to read a image from
+@item @option{-R <expression>}@tab Value for R color
+@item @option{-G <expression>}@tab Value for G color
+@item @option{-B <expression>}@tab Value for B color
+@item @option{-A <expression>}@tab Value for Alpha channel
+@end multitable
+
+Expressions are functions of these variables:
+@multitable @columnfractions .2 .8
+@item @var{N} @tab frame number (starting at zero)
+@item @var{H} @tab frame height
+@item @var{W} @tab frame width
+@item @var{h} @tab image height
+@item @var{w} @tab image width
+@item @var{X} @tab previous x coordinate of text or image
+@item @var{Y} @tab previous y coordinate of text or image
+@end multitable
+
+You may also use the constants @var{PI}, @var{E}, and the math functions available at the
+FFmpeg formula evaluator at (@url{ffmpeg-doc.html#SEC13}), except @var{bits2qp(bits)}
+and @var{qp2bits(qp)}.
+
+Usage examples:
+
+@example
+   # Remember to set the path to your fonts
+   FONTPATH="/cygdrive/c/WINDOWS/Fonts/"
+   FONTPATH="$FONTPATH:/usr/share/imlib2/data/fonts/"
+   FONTPATH="$FONTPATH:/usr/X11R6/lib/X11/fonts/TTF/"
+   export FONTPATH
+
+   # Bulb dancing in a Lissajous pattern
+   ffmpeg -i input.avi -vhook \
+     'vhook/imlib2.dll -x W*(0.5+0.25*sin(N/47*PI))-w/2 -y H*(0.5+0.50*cos(N/97*PI))-h/2 -i /usr/share/imlib2/data/images/bulb.png' \
+     -acodec copy -sameq output.avi
+
+   # Text scrolling
+   ffmpeg -i input.avi -vhook \
+     'vhook/imlib2.dll -c red -F Vera.ttf/20 -x 150+0.5*N -y 70+0.25*N -t Hello' \
+     -acodec copy -sameq output.avi
+
+   # Date and time stamp, security-camera style:
+   ffmpeg -r 29.97 -s 320x256 -f video4linux -i /dev/video0 \
+     -vhook 'vhook/imlib2.so -x 0 -y 0 -i black-260x20.png' \
+     -vhook 'vhook/imlib2.so -c white -F VeraBd.ttf/12 -x 0 -y 0 -t %A-%D-%T' \
+     output.avi
+
+     In this example the video is captured from the first video capture card as a
+     320x256 AVI, and a black 260 by 20 pixel PNG image is placed in the upper
+     left corner, with the day, date and time overlaid on it in Vera Bold 12
+     point font. A simple black PNG file 260 pixels wide and 20 pixels tall
+     was created in the GIMP for this purpose.
+
+   # Scrolling credits from a text file
+   ffmpeg -i input.avi -vhook \
+     'vhook/imlib2.so -c white -F VeraBd.ttf/16 -x 100 -y -1.0*N -f credits.txt' \
+     -sameq output.avi
+
+     In this example, the text is stored in a file, and is positioned 100
+     pixels from the left hand edge of the video. The text is scrolled from the
+     bottom up. Making the y factor positive will scroll from the top down.
+     Increasing the magnitude of the y factor makes the text scroll faster,
+     decreasing it makes it scroll slower. Hint: Blank lines containing only
+     a newline are treated as end-of-file. To create blank lines, use lines
+     that consist of space characters only.
+
+   # Scrolling credits with custom color from a text file
+   ffmpeg -i input.avi -vhook \
+     'vhook/imlib2.so -C rgb.txt -c CustomColor1 -F VeraBd.ttf/16 -x 100 -y -1.0*N -f credits.txt' \
+     -sameq output.avi
+
+     This example does the same as the one above, but specifies an rgb.txt file
+     to be used, which has a custom-made color in it.
+
+   # Variable colors
+   ffmpeg -i input.avi -vhook \
+     'vhook/imlib2.so -t Hello -R abs(255*sin(N/47*PI)) -G abs(255*sin(N/47*PI)) -B abs(255*sin(N/47*PI))' \
+     -sameq output.avi
+
+     In this example, the color for the text goes up and down from black to
+     white.
+
+   # Text fade-out
+   ffmpeg -i input.avi -vhook \
+     'vhook/imlib2.so -t Hello -A max(0,255-exp(N/47))' \
+     -sameq output.avi
+
+     In this example, the text fades out in about 10 seconds for a 25 fps input
+     video file.
+
+   # scrolling credits from a graphics file
+   ffmpeg -sameq -i input.avi \
+     -vhook 'vhook/imlib2.so -x 0 -y -1.0*N -i credits.png' output.avi
+
+     In this example, a transparent PNG file the same width as the video
+     (e.g. 320 pixels), but very long, (e.g. 3000 pixels), was created, and
+     text, graphics, brushstrokes, etc, were added to the image. The image
+     is then scrolled up, from the bottom of the frame.
+
+@end example
+
+@section ppm.c
+
+It's basically a launch point for a PPM pipe, so you can use any
+executable (or script) which consumes a PPM on stdin and produces a PPM
+on stdout (and flushes each frame). The Netpbm utilities are a series of
+such programs.
+
+A list of them is here:
+
+@url{http://netpbm.sourceforge.net/doc/directory.html}
+
+Usage example:
+
+@example
+ffmpeg -i input -vhook "/path/to/ppm.so some-ppm-filter args" output
+@end example
+
+@section drawtext.c
+
+This module implements a text overlay for a video image. Currently it
+supports a fixed overlay or reading the text from a file. The string
+is passed through strftime() so that it is easy to imprint the date and
+time onto the image.
+
+Features:
+@itemize @minus
+@item TrueType, Type1 and others via the FreeType2 library
+@item Font kerning (better output)
+@item Line Wrap (put the text that doesn't fit one line on the next line)
+@item Background box (currently in development)
+@item Outline
+@end itemize
+
+Options:
+@multitable @columnfractions .2 .8
+@item @option{-c <color>}          @tab Foreground color of the text ('internet' way) <#RRGGBB> [default #FFFFFF]
+@item @option{-C <color>}          @tab Background color of the text ('internet' way) <#RRGGBB> [default #000000]
+@item @option{-f <font-filename>}  @tab font file to use
+@item @option{-t <text>}           @tab text to display
+@item @option{-T <filename>}       @tab file to read text from
+@item @option{-x <pos>}            @tab x coordinate of the start of the text
+@item @option{-y <pos>}            @tab y coordinate of the start of the text
+@end multitable
+
+Text fonts are being looked for in a FONTPATH environment variable.
+If the FONTPATH environment variable is not available, or is not checked by
+your target (i.e. Cygwin), then specify the full path to the font file as in:
+@example
+-f /usr/X11R6/lib/X11/fonts/TTF/VeraBd.ttf
+@end example
+
+Usage Example:
+@example
+   # Remember to set the path to your fonts
+   FONTPATH="/cygdrive/c/WINDOWS/Fonts/"
+   FONTPATH="$FONTPATH:/usr/share/imlib2/data/fonts/"
+   FONTPATH="$FONTPATH:/usr/X11R6/lib/X11/fonts/TTF/"
+   export FONTPATH
+
+   # Time and date display
+   ffmpeg -f video4linux2 -i /dev/video0 \
+   -vhook 'vhook/drawtext.so -f VeraBd.ttf -t %A-%D-%T' movie.mpg
+
+     This example grabs video from the first capture card and outputs it to an
+     MPEG video, and places "Weekday-dd/mm/yy-hh:mm:ss" at the top left of the
+     frame, updated every second, using the Vera Bold TrueType Font, which
+     should exist in: /usr/X11R6/lib/X11/fonts/TTF/
+@end example
+
+Check the man page for strftime() for all the various ways you can format
+the date and time.
+
+@section watermark.c
+
+Command Line options:
+@multitable @columnfractions .2 .8
+@item @option{-m [0|1]}            @tab Mode (default: 0, see below)
+@item @option{-t 000000 - FFFFFF}  @tab Threshold, six digit hex number
+@item @option{-f <filename>}       @tab Watermark image filename, must be specified!
+@end multitable
+
+MODE 0:
+ The watermark picture works like this (assuming color intensities 0..0xFF):
+ Per color do this:
+ If mask color is 0x80, no change to the original frame.
+ If mask color is < 0x80 the absolute difference is subtracted from the
+ frame. If result < 0, result = 0.
+ If mask color is > 0x80 the absolute difference is added to the
+ frame. If result > 0xFF, result = 0xFF.
+
+ You can override the 0x80 level with the -t flag. E.g. if threshold is
+ 000000 the color value of watermark is added to the destination.
+
+ This way a mask that is visible both in light and dark pictures can be made
+ (e.g. by using a picture generated by the Gimp and the bump map tool).
+
+ An example watermark file is at:
+ @url{http://engene.se/ffmpeg_watermark.gif}
+
+MODE 1:
+ Per color do this:
+ If mask color > threshold color then the watermark pixel is used.
+
+Example usage:
+@example
+   ffmpeg -i infile -vhook '/path/watermark.so -f wm.gif' -an out.mov
+   ffmpeg -i infile -vhook '/path/watermark.so -f wm.gif -m 1 -t 222222' -an out.mov

-@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 -vfilters "[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{-vfilters} 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 Available video filters
-
-When you configure your FFmpeg build, you can disable any of the
-existing video filters.
-The configure output will show the video filters included in your
-build.
-
-Below is a description of the currently available video filters.
-
-@section crop
-
-Crop the input video to @var{x}:@var{y}:@var{width}:@var{height}.
-
-@example
-./ffmpeg -i in.avi -vfilters "crop=0:0:0:240" out.avi
-@end example
-
-@var{x} and @var{y} specify the position of the top-left corner of the
-output (non-cropped) area.
-
-The default value of @var{x} and @var{y} is 0.
-
-The @var{width} and @var{height} parameters specify the width and height
-of the output (non-cropped) area.
-
-A value of 0 is interpreted as the maximum possible size contained in
-the area delimited by the top-left corner at position x:y.
-
-For example the parameters:
-
-@example
-"crop=100:100:0:0"
-@end example
-
-will delimit the rectangle with the top-left corner placed at position
-100:100 and the right-bottom corner corresponding to the right-bottom
-corner of the input image.
-
-The default value of @var{width} and @var{height} is 0.
-
-@section format
-
-Convert the input video to one of the specified pixel formats.
-Libavfilter will try to pick one that is supported for the input to
-the next filter.
-
-The filter accepts a list of pixel format names, separated by ``:'',
-for example ``yuv420p:monow:rgb24''.
-
-The following command:
-
-@example
-./ffmpeg -i in.avi -vfilters "format=yuv420p" out.avi
-@end example
-
-will convert the input video to the format ``yuv420p''.
-
-@section noformat
-
-Force libavfilter not to use any of the specified pixel formats for the
-input to the next filter.
-
-The filter accepts a list of pixel format names, separated by ``:'',
-for example ``yuv420p:monow:rgb24''.
-
-The following command:
-
-@example
-./ffmpeg -i in.avi -vfilters "noformat=yuv420p, vflip" out.avi
-@end example
-
-will make libavfilter use a format different from ``yuv420p'' for the
-input to the vflip filter.
-
-@section null
-
-Pass the source unchanged to the output.
-
-@section scale
-
-Scale the input video to @var{width}:@var{height} and/or convert the image format.
-
-For example the command:
-
-@example
-./ffmpeg -i in.avi -vfilters "scale=200:100" out.avi
-@end example
-
-will scale the input video to a size of 200x100.
-
-If the input image format is different from the format requested by
-the next filter, the scale filter will convert the input to the
-requested format.
-
-If the value for @var{width} or @var{height} is 0, the respective input
-size is used for the output.
-
-If the value for @var{width} or @var{height} is -1, the scale filter will
-use, for the respective output size, a value that maintains the aspect
-ratio of the input image.
-
-The default value of @var{width} and @var{height} is 0.
-
-@section slicify
-
-Pass the images of input video on to next video filter as multiple
-slices.
-
-@example
-./ffmpeg -i in.avi -vfilters "slicify=32" out.avi
-@end example
-
-The filter accepts the slice height as parameter. If the parameter is
-not specified it will use the default value of 16.
-
-Adding this in the beginning of filter chains should make filtering
-faster due to better use of the memory cache.
-
-@section unsharp
-
-Sharpen or blur the input video. It accepts the following parameters:
-
-@multitable @columnfractions .2 .5 .1 .1 .1
-@headitem Name @tab Description @tab Min @tab Max @tab Default
-@item @var{luma_msize_x}
-@tab Luma matrix horizontal size
-@tab 3
-@tab 13
-@tab 5
-@item @var{luma_msize_y}
-@tab Luma matrix vertical size

-@item @var{luma_amount}
-@tab Luma effect strength
-@tab -2.0
-@tab 5.0
-@tab 1.0
-@item @var{chroma_msize_x}
-@tab Chroma matrix horizontal size
-@tab 3
-@tab 13
-@tab 0
-@item @var{chroma_msize_y}
-@tab Chroma matrix vertical size
-@tab 3
-@tab 13
-@tab 0
-@item @var{chroma_amount}
-@tab Chroma effect strength
-@tab -2.0
-@tab 5.0
-@tab 0.0
-@end multitable
-

-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.

-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.
-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_array(my_array, 100);
-    printf("};\n");
-
-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.

-
-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.

-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   / \   / \   / \   /

-    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   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

- * Summary of MDCT Coefficient Grouping:
- * The individual MDCT coefficient indices are often referred to in the
- * (E-)AC-3 specification as frequency bins.  These bins are grouped together
- * into subbands of 12 coefficients each.  The subbands are grouped together
- * into bands as defined in the bitstream by the band structures, which
- * determine the number of bands and the size of each band.  The full spectrum
- * of 256 frequency bins is divided into 1 DC bin + 21 subbands = 253 bins.
- * This system of grouping coefficients is used for channel bandwidth, stereo
- * rematrixing, channel coupling, enhanced coupling, and spectral extension.
