2011-10-20 - b35e9e1 - lavu 51.22.0
Add av_strtok() to avstring.h.
2011-xx-xx - xxxxxxx - lavc 53.25.0
Add nb_samples and extended_data fields to AVFrame.
Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
avcodec_decode_audio4() writes output samples to an AVFrame, which allows
audio decoders to use get_buffer().
2011-xx-xx - xxxxxxx - lavc 53.24.0
Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.
Change AVPicture.data[4]/linesize[4] to [8] at next major bump.
Change AVCodecContext.error[4] to [8] at next major bump.
Add AV_NUM_DATA_POINTERS to simplify the bump transition.
2011-11-23 - bbb46f3 - lavu 51.18.0

av_samples_alloc(), to samplefmt.h.

@section Coding Rules
FFmpeg is programmed in the ISO C90 language with a few additional
features from ISO C99, namely:
@subsection Code formatting conventions
There are the following guidelines regarding the indentation in files:
@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'.
@item
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.
@item
You should try to limit your code lines to 80 characters; however, do so if and only if this improves readability.
@end itemize
The presentation is one inspired by 'indent -i4 -kr -nut'.
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
@subsection 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.

@end itemize
@subsection Naming conventions
All names are using underscores (_), not CamelCase. For example, @samp{avfilter_get_video_buffer} is
a valid function name and @samp{AVFilterGetVideo} is not. The only exception from this are structure names;
they should always be in the CamelCase
There are following conventions for naming variables and functions:
@itemize @bullet
@item
For local variables no prefix is required.
@item
For variables and functions declared as @code{static} no prefixes are required.
@item
For variables and functions used internally by the library, @code{ff_} prefix should be used.
For example, @samp{ff_w64_demuxer}.
@item
For variables and functions used internally across multiple libraries, use @code{avpriv_}. For example,
@samp{avpriv_aac_parse_header}.
@item
For exported names, each library has its own prefixes. Just check the existing code and name accordingly.
@end itemize
@subsection Miscellanous conventions
@itemize @bullet
@item
fprintf and printf are forbidden in libavformat and libavcodec,
please use av_log() instead.
@item
Casts should be used only when necessary. Unneeded parentheses
should also be avoided if they don't make the code easier to understand.

The toolchain provided with Xcode is sufficient to build the basic

OSX on PowerPC or ARM (iPhone) requires a preprocessor from
@url{http://github.com/yuvi/gas-preprocessor} to build the optimized
assembler functions. Just download the Perl script and put it somewhere

OSX on amd64 and x86 requires @command{yasm} to build most of the
