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

1021
1022 2011-12-25 - lavfi 2.14.0
1023 e1d9dbf Add a new installed header - buffersrc.h
1024 It contains a new function av_buffersrc_buffer() that allows passing

1026 it allows for direct rendering.
1027 1c9e340 Add avfilter_copy_frame_props() for copying properties from
1028 AVFrame to AVFilterBufferRef.
1029
1030 2011-12-25 - lavc 53.31.0

1048 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
1049 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
1050 avcodec_decode_audio4() writes output samples to an AVFrame, which allows
1051 audio decoders to use get_buffer().
1052
1053 2011-12-04 - 560f773 - lavc 53.24.0
1054 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

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