779 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
780 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
781 Note that this can break user code that includes avcodec.h and uses the
782 'CodecID' identifier. Such code should either #undef CodecID or stop using the
783 CodecID name.
784
785 2012-08-03 - 239fdf1 - lavu 51.37.1 - cpu.h

841
842 2012-05-09 - a5117a2 - lavc 54.13.1
843 For audio formats with fixed frame size, the last frame
844 no longer needs to be padded with silence, libavcodec
845 will handle this internally (effectively all encoders
846 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).
847
848 2012-05-07 - 828bd08 - lavc 54.13.0 - avcodec.h

960
961 2011-12-25 - lavfi 2.14.0
962 e1d9dbf Add a new installed header - buffersrc.h

965 it allows for direct rendering.
966 1c9e340 Add avfilter_copy_frame_props() for copying properties from
967 AVFrame to AVFilterBufferRef.
968
969 2011-12-25 - lavc 53.31.0

987 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
988 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
989 avcodec_decode_audio4() writes output samples to an AVFrame, which allows
990 audio decoders to use get_buffer().
991
992 2011-12-04 - 560f773 - lavc 53.24.0
993 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1880 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1881 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1882 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1883 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1884 PIX_FMT_BGR32_1 are now macros.
1885 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1886 Re-sort the enum PixelFormat list accordingly.
1887 This change breaks API/ABI backward compatibility.
1888
1889 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1890 Add the enum PixelFormat values:
1891 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1892 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

1894 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1895 The Mersenne Twister PRNG implemented through the av_random* functions
1896 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1897 instead.
1898
1899 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1900 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1901 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1902 and av_fifo_realloc2.
1903 In addition, the order of the function arguments of av_fifo_generic_read
1904 was changed to match av_fifo_generic_write.
1905 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1906 applications, they may not use sizeof() or directly access members.
1907
1908 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1909 Introduce a new metadata API (see av_metadata_get() and friends).
1910 The old API is now deprecated and should not be used anymore. This especially
1911 includes the following structure fields:
1912 - AVFormatContext.title
1913 - AVFormatContext.author
1914 - AVFormatContext.copyright
1915 - AVFormatContext.comment
1916 - AVFormatContext.album
1917 - AVFormatContext.year
1918 - AVFormatContext.track
1919 - AVFormatContext.genre
1920 - AVStream.language
1921 - AVStream.filename
1922 - AVProgram.provider_name
1923 - AVProgram.name
1924 - AVChapter.title
