1743
1744 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1745 Add a pts field to AVSubtitle which gives the subtitle packet pts
1746 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1747 not work right without this.
1748
1749 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1750 PKT_FLAG_KEY has been deprecated and will be dropped at the next

1753 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1754 av_lockmgr_register() can be used to register a callback function
1755 that lavc (and in the future, libraries that depend on lavc) can use
1756 to implement mutexes. The application should provide a callback function
1757 that implements the AV_LOCK_* operations described in avcodec.h.
1758 When the lock manager is registered, FFmpeg is guaranteed to behave
1759 correctly in a multi-threaded application.
1760
1761 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1762 av_free_packet() is no longer an inline function. It is now exported.
1763
1764 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1765 Please use NULL instead. This has been supported since r16506
1766 (lavf > 52.23.1, lavc > 52.10.0).
1767
1768 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1769 The old decoding functions are deprecated, all new code should use the
1770 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1771 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1772 argument instead of a const uint8_t *buf / int buf_size pair.
1773
1774 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()

1779 libavcodec/avcodec.h.
1780
1781 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1782 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1783 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1784 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1785 PIX_FMT_BGR32_1 are now macros.
1786 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1787 Re-sort the enum PixelFormat list accordingly.
1788 This change breaks API/ABI backward compatibility.
1789
1790 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1791 Add the enum PixelFormat values:
1792 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1793 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1794
1795 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1796 The Mersenne Twister PRNG implemented through the av_random* functions
1797 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1798 instead.
1799
1800 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1801 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1802 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1803 and av_fifo_realloc2.
1804 In addition, the order of the function arguments of av_fifo_generic_read
1805 was changed to match av_fifo_generic_write.
1806 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1807 applications, they may not use sizeof() or directly access members.
1808
1809 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1810 Introduce a new metadata API (see av_metadata_get() and friends).
1811 The old API is now deprecated and should not be used anymore. This especially
1812 includes the following structure fields:
1813 - AVFormatContext.title
1814 - AVFormatContext.author
1815 - AVFormatContext.copyright
1816 - AVFormatContext.comment
1817 - AVFormatContext.album
1818 - AVFormatContext.year
1819 - AVFormatContext.track
1820 - AVFormatContext.genre
1821 - AVStream.language
1822 - AVStream.filename
1823 - AVProgram.provider_name
1824 - AVProgram.name
1825 - AVChapter.title
