782 To provide backwards compatibility, PixelFormat is now #defined as
783 AVPixelFormat.
784 Note that this can break user code that includes pixfmt.h and uses the
785 'PixelFormat' identifier. Such code should either #undef PixelFormat
786 or stop using the PixelFormat name.
787
788 2012-10-05 - e7ba5b1 - lavr 1.0.0 - avresample.h
789 Data planes parameters to avresample_convert() and

826 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
827 Note that this can break user code that includes avcodec.h and uses the
828 'CodecID' identifier. Such code should either #undef CodecID or stop using the
829 CodecID name.
830
831 2012-08-03 - 239fdf1 - lavu 51.37.1 - cpu.h

889 For audio formats with fixed frame size, the last frame
890 no longer needs to be padded with silence, libavcodec
891 will handle this internally (effectively all encoders
892 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

1006
1007 2011-12-25 - lavfi 2.14.0
1008 e1d9dbf Add a new installed header - buffersrc.h
1009 It contains a new function av_buffersrc_buffer() that allows passing
1010 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
1011 it allows for direct rendering.
1012 1c9e340 Add avfilter_copy_frame_props() for copying properties from
1013 AVFrame to AVFilterBufferRef.
1014
1015 2011-12-25 - lavc 53.31.0
1016 Add the following new fields to AVFrame:

1033 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
1034 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
1035 avcodec_decode_audio4() writes output samples to an AVFrame, which allows
1036 audio decoders to use get_buffer().
1037
1038 2011-12-04 - 560f773 - lavc 53.24.0
1039 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1887 This is now an unsigned int instead of a signed int.
1888
1889 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1890 Add a pts field to AVSubtitle which gives the subtitle packet pts
1891 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1892 not work right without this.
1893
1894 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1895 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1896 major version. Use AV_PKT_FLAG_KEY instead.
1897
1898 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1899 av_lockmgr_register() can be used to register a callback function
1900 that lavc (and in the future, libraries that depend on lavc) can use
1901 to implement mutexes. The application should provide a callback function
1902 that implements the AV_LOCK_* operations described in avcodec.h.
1903 When the lock manager is registered, FFmpeg is guaranteed to behave
1904 correctly in a multi-threaded application.
1905
1906 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1907 av_free_packet() is no longer an inline function. It is now exported.
1908
1909 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1910 Please use NULL instead. This has been supported since r16506
1911 (lavf > 52.23.1, lavc > 52.10.0).
1912
1913 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1914 The old decoding functions are deprecated, all new code should use the
1915 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1916 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1917 argument instead of a const uint8_t *buf / int buf_size pair.
1918
1919 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1920 Introduce the av_fifo_space() function.
1921
1922 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1923 Move AVPacket declaration from libavformat/avformat.h to
1924 libavcodec/avcodec.h.
1925
1926 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1927 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1928 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1929 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1930 PIX_FMT_BGR32_1 are now macros.
1931 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1932 Re-sort the enum PixelFormat list accordingly.
1933 This change breaks API/ABI backward compatibility.
1934
1935 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1936 Add the enum PixelFormat values:
1937 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1938 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1939
1940 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1941 The Mersenne Twister PRNG implemented through the av_random* functions
1942 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1943 instead.
1944
1945 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1946 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1947 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1948 and av_fifo_realloc2.
1949 In addition, the order of the function arguments of av_fifo_generic_read
1950 was changed to match av_fifo_generic_write.
1951 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1952 applications, they may not use sizeof() or directly access members.
1953
1954 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1955 Introduce a new metadata API (see av_metadata_get() and friends).
1956 The old API is now deprecated and should not be used anymore. This especially
1957 includes the following structure fields:
1958 - AVFormatContext.title
1959 - AVFormatContext.author
1960 - AVFormatContext.copyright
1961 - AVFormatContext.comment
1962 - AVFormatContext.album
1963 - AVFormatContext.year
1964 - AVFormatContext.track
1965 - AVFormatContext.genre
1966 - AVStream.language
1967 - AVStream.filename
1968 - AVProgram.provider_name
1969 - AVProgram.name
1970 - AVChapter.title
