838 will handle this internally (effectively all encoders

955 e1d9dbf Add a new installed header - buffersrc.h
956 It contains a new function av_buffersrc_buffer() that allows passing

1805 Introduce the avfilter_next() function.
1807 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1808 Change the signature of avfilter_register() to make it return an
1809 int. This is required since now the registration operation may fail.
1811 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1812 Make the pixdesc.h API public.

1836 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1837 Add a pts field to AVSubtitle which gives the subtitle packet pts
1838 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1839 not work right without this.
1841 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1842 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1843 major version. Use AV_PKT_FLAG_KEY instead.
1845 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1846 av_lockmgr_register() can be used to register a callback function
1847 that lavc (and in the future, libraries that depend on lavc) can use
1848 to implement mutexes. The application should provide a callback function
1849 that implements the AV_LOCK_* operations described in avcodec.h.
1850 When the lock manager is registered, FFmpeg is guaranteed to behave
1851 correctly in a multi-threaded application.
1853 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1854 av_free_packet() is no longer an inline function. It is now exported.
1856 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1857 Please use NULL instead. This has been supported since r16506
1858 (lavf > 52.23.1, lavc > 52.10.0).
1860 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1861 The old decoding functions are deprecated, all new code should use the
1862 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1863 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1864 argument instead of a const uint8_t *buf / int buf_size pair.
1866 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1867 Introduce the av_fifo_space() function.
1869 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1870 Move AVPacket declaration from libavformat/avformat.h to
1871 libavcodec/avcodec.h.
1873 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1874 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1875 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1876 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1877 PIX_FMT_BGR32_1 are now macros.
1878 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1879 Re-sort the enum PixelFormat list accordingly.
1880 This change breaks API/ABI backward compatibility.
1882 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1883 Add the enum PixelFormat values:
1884 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1885 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1887 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1888 The Mersenne Twister PRNG implemented through the av_random* functions
1889 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1892 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1893 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1894 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1895 and av_fifo_realloc2.
1896 In addition, the order of the function arguments of av_fifo_generic_read
1897 was changed to match av_fifo_generic_write.
1898 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1899 applications, they may not use sizeof() or directly access members.
1901 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1902 Introduce a new metadata API (see av_metadata_get() and friends).
1903 The old API is now deprecated and should not be used anymore. This especially
1904 includes the following structure fields:
1905 - AVFormatContext.title
1906 - AVFormatContext.author
1907 - AVFormatContext.copyright
1908 - AVFormatContext.comment
1909 - AVFormatContext.album
1910 - AVFormatContext.year
1911 - AVFormatContext.track
1912 - AVFormatContext.genre
1915 - AVProgram.provider_name
