761
762 2012-09-24 - a42aada - lavc 54.28.0 - avcodec.h
763 Add avcodec_free_frame(). This function must now
764 be used for freeing an AVFrame.
765
766 2012-09-12 - 8919fee - lavu 51.41.0 - audioconvert.h
767 Added AV_CH_LOW_FREQUENCY_2 channel mask value.

794 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
795 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
796 Note that this can break user code that includes avcodec.h and uses the
797 'CodecID' identifier. Such code should either #undef CodecID or stop using the
798 CodecID name.
799
800 2012-08-03 - 239fdf1 - lavu 51.37.1 - cpu.h
801 lsws 2.1.1 - swscale.h

856
857 2012-05-09 - a5117a2 - lavc 54.13.1
858 For audio formats with fixed frame size, the last frame
859 no longer needs to be padded with silence, libavcodec
860 will handle this internally (effectively all encoders
861 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).
862
863 2012-05-07 - 828bd08 - lavc 54.13.0 - avcodec.h

957
958 ------------------------------8<-------------------------------------
959 0.8 branch was cut here
960 ----------------------------->8--------------------------------------

975
976 2011-12-25 - lavfi 2.14.0
977 e1d9dbf Add a new installed header - buffersrc.h

979 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
980 it allows for direct rendering.
981 1c9e340 Add avfilter_copy_frame_props() for copying properties from
982 AVFrame to AVFilterBufferRef.
983
984 2011-12-25 - lavc 53.31.0

1002 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
1003 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
1004 avcodec_decode_audio4() writes output samples to an AVFrame, which allows
1005 audio decoders to use get_buffer().
1006
1007 2011-12-04 - 560f773 - lavc 53.24.0
1008 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1883 The old decoding functions are deprecated, all new code should use the
1884 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1885 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1886 argument instead of a const uint8_t *buf / int buf_size pair.
1887
1888 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1889 Introduce the av_fifo_space() function.
1890
1891 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1892 Move AVPacket declaration from libavformat/avformat.h to
1893 libavcodec/avcodec.h.
1894
1895 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1896 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1897 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1898 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1899 PIX_FMT_BGR32_1 are now macros.
1900 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1901 Re-sort the enum PixelFormat list accordingly.
1902 This change breaks API/ABI backward compatibility.
1903
1904 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1905 Add the enum PixelFormat values:
1906 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1907 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1908
1909 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1910 The Mersenne Twister PRNG implemented through the av_random* functions
1911 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1912 instead.
1913
1914 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1915 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1916 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1917 and av_fifo_realloc2.
1918 In addition, the order of the function arguments of av_fifo_generic_read
1919 was changed to match av_fifo_generic_write.
1920 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1921 applications, they may not use sizeof() or directly access members.
1922
1923 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1924 Introduce a new metadata API (see av_metadata_get() and friends).
1925 The old API is now deprecated and should not be used anymore. This especially
1926 includes the following structure fields:
1927 - AVFormatContext.title
1928 - AVFormatContext.author
1929 - AVFormatContext.copyright
1930 - AVFormatContext.comment
1931 - AVFormatContext.album
1932 - AVFormatContext.year
1933 - AVFormatContext.track
1934 - AVFormatContext.genre
1935 - AVStream.language
1936 - AVStream.filename
1937 - AVProgram.provider_name
1938 - AVProgram.name
1939 - AVChapter.title
