804 'PixelFormat' identifier. Such code should either #undef PixelFormat
805 or stop using the PixelFormat name.

908 For audio formats with fixed frame size, the last frame
909 no longer needs to be padded with silence, libavcodec
910 will handle this internally (effectively all encoders

1025
1026 2011-12-25 - lavfi 2.14.0
1027 e1d9dbf Add a new installed header - buffersrc.h
1028 It contains a new function av_buffersrc_buffer() that allows passing
1029 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
1030 it allows for direct rendering.
1031 1c9e340 Add avfilter_copy_frame_props() for copying properties from
1032 AVFrame to AVFilterBufferRef.
1033
1034 2011-12-25 - lavc 53.31.0
1035 Add the following new fields to AVFrame:

1052 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
1053 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
1054 avcodec_decode_audio4() writes output samples to an AVFrame, which allows
1055 audio decoders to use get_buffer().
1056
1057 2011-12-04 - 560f773 - lavc 53.24.0
1058 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1092 This will allow passing AVOptions to protocols after lavf
1093 54.0.
1094
1095 2011-11-06 - ba04ecf - lavu 51.14.0

1884 Make the pixdesc.h API public.
1885
1886 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1887 Add a next field to AVFilter, this is used for simplifying the
1888 registration and management of the registered filters.
1889
1890 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
1891 Add a description field to AVFilter.
1892
1893 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1894 Change the interface of avfilter_make_format_list() from
1895 avfilter_make_format_list(int n, ...) to
1896 avfilter_make_format_list(enum PixelFormat *pix_fmts).
1897
1898 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
1899 Make avfilter_get_video_buffer() recursive and add the w and h
1900 parameters to it.
1901
1902 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
1903 Add w and h fields to AVFilterPic.
1904
1905 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1906 This is now an unsigned int instead of a signed int.
1907
1908 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1909 Add a pts field to AVSubtitle which gives the subtitle packet pts
1910 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1911 not work right without this.
1912
1913 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1914 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1915 major version. Use AV_PKT_FLAG_KEY instead.
1916
1917 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1918 av_lockmgr_register() can be used to register a callback function
1919 that lavc (and in the future, libraries that depend on lavc) can use
1920 to implement mutexes. The application should provide a callback function
1921 that implements the AV_LOCK_* operations described in avcodec.h.
1922 When the lock manager is registered, FFmpeg is guaranteed to behave
1923 correctly in a multi-threaded application.
1924
1925 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1926 av_free_packet() is no longer an inline function. It is now exported.
1927
1928 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1929 Please use NULL instead. This has been supported since r16506
1930 (lavf > 52.23.1, lavc > 52.10.0).
1931
1932 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1933 The old decoding functions are deprecated, all new code should use the
1934 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1935 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1936 argument instead of a const uint8_t *buf / int buf_size pair.
1937
1938 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1939 Introduce the av_fifo_space() function.
1940
1941 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1942 Move AVPacket declaration from libavformat/avformat.h to
1943 libavcodec/avcodec.h.
1944
1945 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1946 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1947 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1948 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1949 PIX_FMT_BGR32_1 are now macros.
1950 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1951 Re-sort the enum PixelFormat list accordingly.
1952 This change breaks API/ABI backward compatibility.
1953
1954 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1955 Add the enum PixelFormat values:
1956 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1957 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1958
1959 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1960 The Mersenne Twister PRNG implemented through the av_random* functions
1961 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1962 instead.
1963
1964 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1965 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1966 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1967 and av_fifo_realloc2.
1968 In addition, the order of the function arguments of av_fifo_generic_read
1969 was changed to match av_fifo_generic_write.
1970 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1971 applications, they may not use sizeof() or directly access members.
1972
1973 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1974 Introduce a new metadata API (see av_metadata_get() and friends).
1975 The old API is now deprecated and should not be used anymore. This especially
1976 includes the following structure fields:
1977 - AVFormatContext.title
1978 - AVFormatContext.author
1979 - AVFormatContext.copyright
1980 - AVFormatContext.comment
1981 - AVFormatContext.album
1982 - AVFormatContext.year
1983 - AVFormatContext.track
1984 - AVFormatContext.genre
1985 - AVStream.language
1986 - AVStream.filename
1987 - AVProgram.provider_name
1988 - AVProgram.name
1989 - AVChapter.title
