909 1c9e340 Add avfilter_copy_frame_props() for copying properties from
910 AVFrame to AVFilterBufferRef.

1762 Make the pixdesc.h API public.

1785
1786 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1787 Add a pts field to AVSubtitle which gives the subtitle packet pts
1788 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1789 not work right without this.
1790
1791 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1792 PKT_FLAG_KEY has been deprecated and will be dropped at the next

1794
1795 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1796 av_lockmgr_register() can be used to register a callback function
1797 that lavc (and in the future, libraries that depend on lavc) can use
1798 to implement mutexes. The application should provide a callback function
1799 that implements the AV_LOCK_* operations described in avcodec.h.
1800 When the lock manager is registered, FFmpeg is guaranteed to behave
1801 correctly in a multi-threaded application.
1802
1803 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1804 av_free_packet() is no longer an inline function. It is now exported.
1805
1806 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1807 Please use NULL instead. This has been supported since r16506
1808 (lavf > 52.23.1, lavc > 52.10.0).
1809
1810 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1811 The old decoding functions are deprecated, all new code should use the
1812 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1813 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1814 argument instead of a const uint8_t *buf / int buf_size pair.
1815
1816 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()

1821 libavcodec/avcodec.h.
1822
1823 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1824 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1825 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1826 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1827 PIX_FMT_BGR32_1 are now macros.
1828 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1829 Re-sort the enum PixelFormat list accordingly.
1830 This change breaks API/ABI backward compatibility.
1831
1832 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1833 Add the enum PixelFormat values:
1834 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1835 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1836
1837 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1838 The Mersenne Twister PRNG implemented through the av_random* functions
1839 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1840 instead.
1841
1842 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1843 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1844 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1845 and av_fifo_realloc2.
1846 In addition, the order of the function arguments of av_fifo_generic_read
1847 was changed to match av_fifo_generic_write.
1848 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1849 applications, they may not use sizeof() or directly access members.
1850
1851 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1852 Introduce a new metadata API (see av_metadata_get() and friends).
1853 The old API is now deprecated and should not be used anymore. This especially
1854 includes the following structure fields:
1855 - AVFormatContext.title
1856 - AVFormatContext.author
1857 - AVFormatContext.copyright
1858 - AVFormatContext.comment
1859 - AVFormatContext.album
1860 - AVFormatContext.year
1861 - AVFormatContext.track
1862 - AVFormatContext.genre
1863 - AVStream.language
1864 - AVStream.filename
1865 - AVProgram.provider_name
1866 - AVProgram.name
1867 - AVChapter.title
