753 2012-10-05 - e7ba5b1 - lavr 1.0.0 - avresample.h
754 Data planes parameters to avresample_convert() and
755 avresample_read() are now uint8_t** instead of void**.
756 Libavresample is now stable.
757
758 2012-09-24 - a42aada - lavc 54.28.0 - avcodec.h
759 Add avcodec_free_frame(). This function must now
760 be used for freeing an AVFrame.
761
762 2012-09-12 - 8919fee - lavu 51.41.0 - audioconvert.h
763 Added AV_CH_LOW_FREQUENCY_2 channel mask value.

789 2012-08-07 - 104e10f - lavc 54.25 - avcodec.h
790 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
791 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
792 Note that this can break user code that includes avcodec.h and uses the
793 'CodecID' identifier. Such code should either #undef CodecID or stop using the
794 CodecID name.
795
796 2012-08-03 - 239fdf1 - lavu 51.37.1 - cpu.h
797 lsws 2.1.1 - swscale.h

823 2012-06-12 - 84b9fbe - lavfi 2.22.0 - avfilter.h
824 Add avfilter_pad_get_type() and avfilter_pad_get_name(). Those
825 should now be used instead of accessing AVFilterPad members

852
853 2012-05-09 - a5117a2 - lavc 54.13.1
854 For audio formats with fixed frame size, the last frame
855 no longer needs to be padded with silence, libavcodec
856 will handle this internally (effectively all encoders
857 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).
858
859 2012-05-07 - 828bd08 - lavc 54.13.0 - avcodec.h

953
954 ------------------------------8<-------------------------------------

971
972 2011-12-25 - lavfi 2.14.0
973 e1d9dbf Add a new installed header - buffersrc.h

975 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
976 it allows for direct rendering.
977 1c9e340 Add avfilter_copy_frame_props() for copying properties from
978 AVFrame to AVFilterBufferRef.
979
980 2011-12-25 - lavc 53.31.0

999 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
1000 avcodec_decode_audio4() writes output samples to an AVFrame, which allows
1001 audio decoders to use get_buffer().
1002
1003 2011-12-04 - 560f773 - lavc 53.24.0
1004 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1879 The old decoding functions are deprecated, all new code should use the
1880 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1881 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1882 argument instead of a const uint8_t *buf / int buf_size pair.
1883
1884 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1885 Introduce the av_fifo_space() function.
1886
1887 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1888 Move AVPacket declaration from libavformat/avformat.h to
1889 libavcodec/avcodec.h.
1890
1891 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1892 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1893 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1894 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1895 PIX_FMT_BGR32_1 are now macros.
1896 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1897 Re-sort the enum PixelFormat list accordingly.
1898 This change breaks API/ABI backward compatibility.
1899
1900 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1901 Add the enum PixelFormat values:
1902 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1903 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1904
1905 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1906 The Mersenne Twister PRNG implemented through the av_random* functions
1907 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1908 instead.
1909
1910 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1911 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1912 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1913 and av_fifo_realloc2.
1914 In addition, the order of the function arguments of av_fifo_generic_read
1915 was changed to match av_fifo_generic_write.
1916 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1917 applications, they may not use sizeof() or directly access members.
1918
1919 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1920 Introduce a new metadata API (see av_metadata_get() and friends).
1921 The old API is now deprecated and should not be used anymore. This especially
1922 includes the following structure fields:
1923 - AVFormatContext.title
1924 - AVFormatContext.author
1925 - AVFormatContext.copyright
1926 - AVFormatContext.comment
1927 - AVFormatContext.album
1928 - AVFormatContext.year
1929 - AVFormatContext.track
1930 - AVFormatContext.genre
1931 - AVStream.language
1932 - AVStream.filename
1933 - AVProgram.provider_name
1934 - AVProgram.name
1935 - AVChapter.title
