778 Rename PixelFormat to AVPixelFormat and all PIX_FMT_* to AV_PIX_FMT_*.
779 To provide backwards compatibility, PixelFormat is now #defined as
780 AVPixelFormat.
781 Note that this can break user code that includes pixfmt.h and uses the
782 'PixelFormat' identifier. Such code should either #undef PixelFormat
783 or stop using the PixelFormat name.
784
785 2012-10-05 - e7ba5b1 - lavr 1.0.0 - avresample.h
786 Data planes parameters to avresample_convert() and

822 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
823 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
824 Note that this can break user code that includes avcodec.h and uses the
825 'CodecID' identifier. Such code should either #undef CodecID or stop using the
826 CodecID name.
827
828 2012-08-03 - 239fdf1 - lavu 51.37.1 - cpu.h

885 2012-05-09 - a5117a2 - lavc 54.13.1
886 For audio formats with fixed frame size, the last frame
887 no longer needs to be padded with silence, libavcodec
888 will handle this internally (effectively all encoders
889 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

1003
1004 2011-12-25 - lavfi 2.14.0
1005 e1d9dbf Add a new installed header - buffersrc.h
1006 It contains a new function av_buffersrc_buffer() that allows passing
1007 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
1008 it allows for direct rendering.
1009 1c9e340 Add avfilter_copy_frame_props() for copying properties from
1010 AVFrame to AVFilterBufferRef.
1011
1012 2011-12-25 - lavc 53.31.0
1013 Add the following new fields to AVFrame:

1030 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
1031 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
1032 avcodec_decode_audio4() writes output samples to an AVFrame, which allows
1033 audio decoders to use get_buffer().
1034
1035 2011-12-04 - 560f773 - lavc 53.24.0
1036 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1886 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1887 Add a pts field to AVSubtitle which gives the subtitle packet pts
1888 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1889 not work right without this.
1890
1891 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1892 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1893 major version. Use AV_PKT_FLAG_KEY instead.
1894
1895 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1896 av_lockmgr_register() can be used to register a callback function
1897 that lavc (and in the future, libraries that depend on lavc) can use
1898 to implement mutexes. The application should provide a callback function
1899 that implements the AV_LOCK_* operations described in avcodec.h.
1900 When the lock manager is registered, FFmpeg is guaranteed to behave
1901 correctly in a multi-threaded application.
1902
1903 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1904 av_free_packet() is no longer an inline function. It is now exported.
1905
1906 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1907 Please use NULL instead. This has been supported since r16506
1908 (lavf > 52.23.1, lavc > 52.10.0).
1909
1910 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1911 The old decoding functions are deprecated, all new code should use the
1912 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1913 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1914 argument instead of a const uint8_t *buf / int buf_size pair.
1915
1916 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1917 Introduce the av_fifo_space() function.
1918
1919 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1920 Move AVPacket declaration from libavformat/avformat.h to
1921 libavcodec/avcodec.h.
1922
1923 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1924 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1925 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1926 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1927 PIX_FMT_BGR32_1 are now macros.
1928 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1929 Re-sort the enum PixelFormat list accordingly.
1930 This change breaks API/ABI backward compatibility.
1931
1932 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1933 Add the enum PixelFormat values:
1934 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1935 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1936
1937 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1938 The Mersenne Twister PRNG implemented through the av_random* functions
1939 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1940 instead.
1941
1942 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1943 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1944 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1945 and av_fifo_realloc2.
1946 In addition, the order of the function arguments of av_fifo_generic_read
1947 was changed to match av_fifo_generic_write.
1948 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1949 applications, they may not use sizeof() or directly access members.
1950
1951 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1952 Introduce a new metadata API (see av_metadata_get() and friends).
1953 The old API is now deprecated and should not be used anymore. This especially
1954 includes the following structure fields:
1955 - AVFormatContext.title
1956 - AVFormatContext.author
1957 - AVFormatContext.copyright
1958 - AVFormatContext.comment
1959 - AVFormatContext.album
1960 - AVFormatContext.year
1961 - AVFormatContext.track
1962 - AVFormatContext.genre
1963 - AVStream.language
1964 - AVStream.filename
1965 - AVProgram.provider_name
1966 - AVProgram.name
1967 - AVChapter.title
