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

839 2012-05-09 - a5117a2 - lavc 54.13.1
840 For audio formats with fixed frame size, the last frame
841 no longer needs to be padded with silence, libavcodec
842 will handle this internally (effectively all encoders
843 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).
844
845 2012-05-07 - 828bd08 - lavc 54.13.0 - avcodec.h

957
958 2011-12-25 - lavfi 2.14.0
959 e1d9dbf Add a new installed header - buffersrc.h

962 it allows for direct rendering.
963 1c9e340 Add avfilter_copy_frame_props() for copying properties from
964 AVFrame to AVFilterBufferRef.
965
966 2011-12-25 - lavc 53.31.0

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

1877 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1878 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1879 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1880 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1881 PIX_FMT_BGR32_1 are now macros.
1882 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1883 Re-sort the enum PixelFormat list accordingly.
1884 This change breaks API/ABI backward compatibility.
1885
1886 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1887 Add the enum PixelFormat values:
1888 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1889 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

1891 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1892 The Mersenne Twister PRNG implemented through the av_random* functions
1893 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1894 instead.
1895
1896 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1897 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1898 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1899 and av_fifo_realloc2.
1900 In addition, the order of the function arguments of av_fifo_generic_read
1901 was changed to match av_fifo_generic_write.
1902 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1903 applications, they may not use sizeof() or directly access members.
1904
1905 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1906 Introduce a new metadata API (see av_metadata_get() and friends).
1907 The old API is now deprecated and should not be used anymore. This especially
1908 includes the following structure fields:
1909 - AVFormatContext.title
1910 - AVFormatContext.author
1911 - AVFormatContext.copyright
1912 - AVFormatContext.comment
1913 - AVFormatContext.album
1914 - AVFormatContext.year
1915 - AVFormatContext.track
1916 - AVFormatContext.genre
1917 - AVStream.language
1918 - AVStream.filename
1919 - AVProgram.provider_name
1920 - AVProgram.name
1921 - AVChapter.title
