807 'PixelFormat' identifier. Such code should either #undef PixelFormat
808 or stop using the PixelFormat name.

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

1028
1029 2011-12-25 - lavfi 2.14.0
1030 e1d9dbf Add a new installed header - buffersrc.h
1031 It contains a new function av_buffersrc_buffer() that allows passing

1033 it allows for direct rendering.
1034 1c9e340 Add avfilter_copy_frame_props() for copying properties from
1035 AVFrame to AVFilterBufferRef.
1036
1037 2011-12-25 - lavc 53.31.0

1055 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
1056 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
1057 avcodec_decode_audio4() writes output samples to an AVFrame, which allows
1058 audio decoders to use get_buffer().
1059
1060 2011-12-04 - 560f773 - lavc 53.24.0
1061 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1887 Make the pixdesc.h API public.
1888
1889 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1890 Add a next field to AVFilter, this is used for simplifying the
1891 registration and management of the registered filters.
1892
1893 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
1894 Add a description field to AVFilter.
1895
1896 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1897 Change the interface of avfilter_make_format_list() from
1898 avfilter_make_format_list(int n, ...) to
1899 avfilter_make_format_list(enum PixelFormat *pix_fmts).
1900
1901 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
1902 Make avfilter_get_video_buffer() recursive and add the w and h
1903 parameters to it.
1904
1905 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
1906 Add w and h fields to AVFilterPic.
1907
1908 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1909 This is now an unsigned int instead of a signed int.
1910
1911 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1912 Add a pts field to AVSubtitle which gives the subtitle packet pts
1913 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1914 not work right without this.
1915
1916 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1917 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1918 major version. Use AV_PKT_FLAG_KEY instead.
1919
1920 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1921 av_lockmgr_register() can be used to register a callback function
1922 that lavc (and in the future, libraries that depend on lavc) can use
1923 to implement mutexes. The application should provide a callback function
1924 that implements the AV_LOCK_* operations described in avcodec.h.
1925 When the lock manager is registered, FFmpeg is guaranteed to behave
1926 correctly in a multi-threaded application.
1927
1928 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1929 av_free_packet() is no longer an inline function. It is now exported.
1930
1931 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1932 Please use NULL instead. This has been supported since r16506
1933 (lavf > 52.23.1, lavc > 52.10.0).
1934
1935 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1936 The old decoding functions are deprecated, all new code should use the
1937 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1938 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1939 argument instead of a const uint8_t *buf / int buf_size pair.
1940
1941 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1942 Introduce the av_fifo_space() function.
1943
1944 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1945 Move AVPacket declaration from libavformat/avformat.h to
1946 libavcodec/avcodec.h.
1947
1948 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1949 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1950 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1951 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1952 PIX_FMT_BGR32_1 are now macros.
1953 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1954 Re-sort the enum PixelFormat list accordingly.
1955 This change breaks API/ABI backward compatibility.
1956
1957 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1958 Add the enum PixelFormat values:
1959 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1960 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1961
1962 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1963 The Mersenne Twister PRNG implemented through the av_random* functions
1964 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1965 instead.
1966
1967 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1968 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1969 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1970 and av_fifo_realloc2.
1971 In addition, the order of the function arguments of av_fifo_generic_read
1972 was changed to match av_fifo_generic_write.
1973 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1974 applications, they may not use sizeof() or directly access members.
1975
1976 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1977 Introduce a new metadata API (see av_metadata_get() and friends).
1978 The old API is now deprecated and should not be used anymore. This especially
1979 includes the following structure fields:
1980 - AVFormatContext.title
1981 - AVFormatContext.author
1982 - AVFormatContext.copyright
1983 - AVFormatContext.comment
1984 - AVFormatContext.album
1985 - AVFormatContext.year
1986 - AVFormatContext.track
1987 - AVFormatContext.genre
1988 - AVStream.language
1989 - AVStream.filename
1990 - AVProgram.provider_name
1991 - AVProgram.name
1992 - AVChapter.title
