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

1801 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1802 Introduce the avfilter_next() function.
1804 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1805 Change the signature of avfilter_register() to make it return an
1806 int. This is required since now the registration operation may fail.
1808 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1809 Make the pixdesc.h API public.
1811 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

1833 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1834 Add a pts field to AVSubtitle which gives the subtitle packet pts
1835 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1836 not work right without this.
1838 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1839 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1840 major version. Use AV_PKT_FLAG_KEY instead.
1842 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1843 av_lockmgr_register() can be used to register a callback function
1844 that lavc (and in the future, libraries that depend on lavc) can use
1845 to implement mutexes. The application should provide a callback function
1846 that implements the AV_LOCK_* operations described in avcodec.h.
1847 When the lock manager is registered, FFmpeg is guaranteed to behave
1848 correctly in a multi-threaded application.
1850 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1851 av_free_packet() is no longer an inline function. It is now exported.
1853 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1854 Please use NULL instead. This has been supported since r16506
1855 (lavf > 52.23.1, lavc > 52.10.0).
1857 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1858 The old decoding functions are deprecated, all new code should use the
1859 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1860 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1861 argument instead of a const uint8_t *buf / int buf_size pair.
1863 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1864 Introduce the av_fifo_space() function.
1866 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1867 Move AVPacket declaration from libavformat/avformat.h to
1868 libavcodec/avcodec.h.
1870 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1871 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1872 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1873 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1874 PIX_FMT_BGR32_1 are now macros.
1875 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1876 Re-sort the enum PixelFormat list accordingly.
1877 This change breaks API/ABI backward compatibility.
1879 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1880 Add the enum PixelFormat values:
1881 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1882 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1884 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1885 The Mersenne Twister PRNG implemented through the av_random* functions
1886 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1889 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1890 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1891 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1892 and av_fifo_realloc2.
1893 In addition, the order of the function arguments of av_fifo_generic_read
1894 was changed to match av_fifo_generic_write.
1895 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1896 applications, they may not use sizeof() or directly access members.
1898 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1899 Introduce a new metadata API (see av_metadata_get() and friends).
1900 The old API is now deprecated and should not be used anymore. This especially
1901 includes the following structure fields:
1902 - AVFormatContext.title
1903 - AVFormatContext.author
1904 - AVFormatContext.copyright
1905 - AVFormatContext.comment
1906 - AVFormatContext.album
1907 - AVFormatContext.year
1908 - AVFormatContext.track
1909 - AVFormatContext.genre
1912 - AVProgram.provider_name
