1825 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1826 Introduce the avfilter_next() function.
1828 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1829 Change the signature of avfilter_register() to make it return an
1830 int. This is required since now the registration operation may fail.
1832 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1833 Make the pixdesc.h API public.

1857 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1858 Add a pts field to AVSubtitle which gives the subtitle packet pts
1859 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1860 not work right without this.
1862 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1863 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1864 major version. Use AV_PKT_FLAG_KEY instead.
1866 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1867 av_lockmgr_register() can be used to register a callback function
1868 that lavc (and in the future, libraries that depend on lavc) can use
1869 to implement mutexes. The application should provide a callback function
1870 that implements the AV_LOCK_* operations described in avcodec.h.
1871 When the lock manager is registered, FFmpeg is guaranteed to behave
1872 correctly in a multi-threaded application.
1874 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1875 av_free_packet() is no longer an inline function. It is now exported.
1877 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1878 Please use NULL instead. This has been supported since r16506
1879 (lavf > 52.23.1, lavc > 52.10.0).
1881 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1882 The old decoding functions are deprecated, all new code should use the
1883 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1884 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1885 argument instead of a const uint8_t *buf / int buf_size pair.
1887 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1888 Introduce the av_fifo_space() function.
1890 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1891 Move AVPacket declaration from libavformat/avformat.h to
1892 libavcodec/avcodec.h.
1894 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1895 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1896 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1897 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1898 PIX_FMT_BGR32_1 are now macros.
1899 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1900 Re-sort the enum PixelFormat list accordingly.
1901 This change breaks API/ABI backward compatibility.
1903 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1904 Add the enum PixelFormat values:
1905 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1906 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1908 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1909 The Mersenne Twister PRNG implemented through the av_random* functions
1910 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1913 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1914 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1915 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1916 and av_fifo_realloc2.
1917 In addition, the order of the function arguments of av_fifo_generic_read
1918 was changed to match av_fifo_generic_write.
1919 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1920 applications, they may not use sizeof() or directly access members.
1922 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1923 Introduce a new metadata API (see av_metadata_get() and friends).
1924 The old API is now deprecated and should not be used anymore. This especially
1925 includes the following structure fields:
1926 - AVFormatContext.title
1927 - AVFormatContext.author
1928 - AVFormatContext.copyright
1929 - AVFormatContext.comment
1930 - AVFormatContext.album
1931 - AVFormatContext.year
1932 - AVFormatContext.track
1933 - AVFormatContext.genre
1936 - AVProgram.provider_name
