1766 Remove the next field from AVFilter, this is not anymore required.
1768 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1769 Introduce the avfilter_next() function.
1771 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1772 Change the signature of avfilter_register() to make it return an
1773 int. This is required since now the registration operation may fail.
1775 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1776 Make the pixdesc.h API public.
1778 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

1800 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1801 Add a pts field to AVSubtitle which gives the subtitle packet pts
1802 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1803 not work right without this.
1805 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1806 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1807 major version. Use AV_PKT_FLAG_KEY instead.
1809 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1810 av_lockmgr_register() can be used to register a callback function
1811 that lavc (and in the future, libraries that depend on lavc) can use
1812 to implement mutexes. The application should provide a callback function
1813 that implements the AV_LOCK_* operations described in avcodec.h.
1814 When the lock manager is registered, FFmpeg is guaranteed to behave
1815 correctly in a multi-threaded application.
1817 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1818 av_free_packet() is no longer an inline function. It is now exported.
1820 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1821 Please use NULL instead. This has been supported since r16506
1822 (lavf > 52.23.1, lavc > 52.10.0).
1824 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1825 The old decoding functions are deprecated, all new code should use the
1826 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1827 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1828 argument instead of a const uint8_t *buf / int buf_size pair.
1830 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1831 Introduce the av_fifo_space() function.
1833 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1834 Move AVPacket declaration from libavformat/avformat.h to
1835 libavcodec/avcodec.h.
1837 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1838 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1839 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1840 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1841 PIX_FMT_BGR32_1 are now macros.
1842 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1843 Re-sort the enum PixelFormat list accordingly.
1844 This change breaks API/ABI backward compatibility.
1846 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1847 Add the enum PixelFormat values:
1848 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1849 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1851 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1852 The Mersenne Twister PRNG implemented through the av_random* functions
1853 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1856 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1857 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1858 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1859 and av_fifo_realloc2.
1860 In addition, the order of the function arguments of av_fifo_generic_read
1861 was changed to match av_fifo_generic_write.
1862 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1863 applications, they may not use sizeof() or directly access members.
1865 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1866 Introduce a new metadata API (see av_metadata_get() and friends).
1867 The old API is now deprecated and should not be used anymore. This especially
1868 includes the following structure fields:
1869 - AVFormatContext.title
1870 - AVFormatContext.author
1871 - AVFormatContext.copyright
1872 - AVFormatContext.comment
1873 - AVFormatContext.album
1874 - AVFormatContext.year
1875 - AVFormatContext.track
1876 - AVFormatContext.genre
1879 - AVProgram.provider_name
