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

981 e1d9dbf Add a new installed header - buffersrc.h
982 It contains a new function av_buffersrc_buffer() that allows passing
983 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()

1009 audio decoders to use get_buffer().
1011 2011-12-04 - 560f773 - lavc 53.24.0
1012 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1833 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1834 Change the signature of avfilter_register() to make it return an
1835 int. This is required since now the registration operation may fail.

1862 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1863 Add a pts field to AVSubtitle which gives the subtitle packet pts
1864 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

1867 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1868 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1869 major version. Use AV_PKT_FLAG_KEY instead.
1871 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1872 av_lockmgr_register() can be used to register a callback function
1873 that lavc (and in the future, libraries that depend on lavc) can use
1874 to implement mutexes. The application should provide a callback function
1875 that implements the AV_LOCK_* operations described in avcodec.h.
1876 When the lock manager is registered, FFmpeg is guaranteed to behave
1877 correctly in a multi-threaded application.
1879 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1880 av_free_packet() is no longer an inline function. It is now exported.
1882 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1883 Please use NULL instead. This has been supported since r16506
1884 (lavf > 52.23.1, lavc > 52.10.0).
1886 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1887 The old decoding functions are deprecated, all new code should use the
1888 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1889 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1890 argument instead of a const uint8_t *buf / int buf_size pair.
1892 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1893 Introduce the av_fifo_space() function.
1895 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1896 Move AVPacket declaration from libavformat/avformat.h to
1897 libavcodec/avcodec.h.
1899 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1900 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1901 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1902 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1903 PIX_FMT_BGR32_1 are now macros.
1904 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1905 Re-sort the enum PixelFormat list accordingly.
1906 This change breaks API/ABI backward compatibility.
1908 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1909 Add the enum PixelFormat values:
1910 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1911 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1913 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1914 The Mersenne Twister PRNG implemented through the av_random* functions
1915 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1918 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1919 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1920 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1921 and av_fifo_realloc2.
1922 In addition, the order of the function arguments of av_fifo_generic_read
1923 was changed to match av_fifo_generic_write.
1924 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1925 applications, they may not use sizeof() or directly access members.
1927 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1928 Introduce a new metadata API (see av_metadata_get() and friends).
1929 The old API is now deprecated and should not be used anymore. This especially
1930 includes the following structure fields:
1931 - AVFormatContext.title
1932 - AVFormatContext.author
1933 - AVFormatContext.copyright
1934 - AVFormatContext.comment
1935 - AVFormatContext.album
1936 - AVFormatContext.year
1937 - AVFormatContext.track
1938 - AVFormatContext.genre
1941 - AVProgram.provider_name
