1765 Make the pixdesc.h API public.

1788
1789 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1790 Add a pts field to AVSubtitle which gives the subtitle packet pts
1791 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1792 not work right without this.
1793
1794 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1795 PKT_FLAG_KEY has been deprecated and will be dropped at the next

1798 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1799 av_lockmgr_register() can be used to register a callback function
1800 that lavc (and in the future, libraries that depend on lavc) can use
1801 to implement mutexes. The application should provide a callback function
1802 that implements the AV_LOCK_* operations described in avcodec.h.
1803 When the lock manager is registered, FFmpeg is guaranteed to behave
1804 correctly in a multi-threaded application.
1805
1806 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1807 av_free_packet() is no longer an inline function. It is now exported.
1808
1809 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1810 Please use NULL instead. This has been supported since r16506
1811 (lavf > 52.23.1, lavc > 52.10.0).
1812
1813 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1814 The old decoding functions are deprecated, all new code should use the
1815 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1816 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1817 argument instead of a const uint8_t *buf / int buf_size pair.
1818
1819 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()

1824 libavcodec/avcodec.h.
1825
1826 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1827 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1828 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1829 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1830 PIX_FMT_BGR32_1 are now macros.
1831 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1832 Re-sort the enum PixelFormat list accordingly.
1833 This change breaks API/ABI backward compatibility.
1834
1835 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1836 Add the enum PixelFormat values:
1837 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1838 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1839
1840 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1841 The Mersenne Twister PRNG implemented through the av_random* functions
1842 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1843 instead.
1844
1845 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1846 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1847 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1848 and av_fifo_realloc2.
1849 In addition, the order of the function arguments of av_fifo_generic_read
1850 was changed to match av_fifo_generic_write.
1851 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1852 applications, they may not use sizeof() or directly access members.
1853
1854 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1855 Introduce a new metadata API (see av_metadata_get() and friends).
1856 The old API is now deprecated and should not be used anymore. This especially
1857 includes the following structure fields:
1858 - AVFormatContext.title
1859 - AVFormatContext.author
1860 - AVFormatContext.copyright
1861 - AVFormatContext.comment
1862 - AVFormatContext.album
1863 - AVFormatContext.year
1864 - AVFormatContext.track
1865 - AVFormatContext.genre
1866 - AVStream.language
1867 - AVStream.filename
1868 - AVProgram.provider_name
1869 - AVProgram.name
1870 - AVChapter.title
