848 will handle this internally (effectively all encoders
849 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

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

993 audio decoders to use get_buffer().
995 2011-12-04 - 560f773 - lavc 53.24.0
996 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1817 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1818 Change the signature of avfilter_register() to make it return an
1819 int. This is required since now the registration operation may fail.

1846 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1847 Add a pts field to AVSubtitle which gives the subtitle packet pts
1848 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

1851 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1852 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1853 major version. Use AV_PKT_FLAG_KEY instead.
1855 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1856 av_lockmgr_register() can be used to register a callback function
1857 that lavc (and in the future, libraries that depend on lavc) can use
1858 to implement mutexes. The application should provide a callback function
1859 that implements the AV_LOCK_* operations described in avcodec.h.
1860 When the lock manager is registered, FFmpeg is guaranteed to behave
1861 correctly in a multi-threaded application.
1863 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1864 av_free_packet() is no longer an inline function. It is now exported.
1866 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1867 Please use NULL instead. This has been supported since r16506
1868 (lavf > 52.23.1, lavc > 52.10.0).
1870 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1871 The old decoding functions are deprecated, all new code should use the
1872 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1873 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1874 argument instead of a const uint8_t *buf / int buf_size pair.
1876 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1877 Introduce the av_fifo_space() function.
1879 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1880 Move AVPacket declaration from libavformat/avformat.h to
1881 libavcodec/avcodec.h.
1883 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1884 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1885 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1886 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1887 PIX_FMT_BGR32_1 are now macros.
1888 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1889 Re-sort the enum PixelFormat list accordingly.
1890 This change breaks API/ABI backward compatibility.
1892 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1893 Add the enum PixelFormat values:
1894 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1895 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1897 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1898 The Mersenne Twister PRNG implemented through the av_random* functions
1899 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1902 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1903 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1904 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1905 and av_fifo_realloc2.
1906 In addition, the order of the function arguments of av_fifo_generic_read
1907 was changed to match av_fifo_generic_write.
1908 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1909 applications, they may not use sizeof() or directly access members.
1911 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1912 Introduce a new metadata API (see av_metadata_get() and friends).
1913 The old API is now deprecated and should not be used anymore. This especially
1914 includes the following structure fields:
1915 - AVFormatContext.title
1916 - AVFormatContext.author
1917 - AVFormatContext.copyright
1918 - AVFormatContext.comment
1919 - AVFormatContext.album
1920 - AVFormatContext.year
1921 - AVFormatContext.track
1922 - AVFormatContext.genre
1925 - AVProgram.provider_name
