1718
1719 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()

1724 Make the pixdesc.h API public.
1725
1726 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1727 Add a next field to AVFilter, this is used for simplifying the
1728 registration and management of the registered filters.

1747
1748 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1749 Add a pts field to AVSubtitle which gives the subtitle packet pts
1750 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1751 not work right without this.
1752
1753 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1754 PKT_FLAG_KEY has been deprecated and will be dropped at the next

1756
1757 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1758 av_lockmgr_register() can be used to register a callback function
1759 that lavc (and in the future, libraries that depend on lavc) can use
1760 to implement mutexes. The application should provide a callback function
1761 that implements the AV_LOCK_* operations described in avcodec.h.
1762 When the lock manager is registered, FFmpeg is guaranteed to behave
1763 correctly in a multi-threaded application.
1764
1765 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1766 av_free_packet() is no longer an inline function. It is now exported.
1767
1768 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1769 Please use NULL instead. This has been supported since r16506
1770 (lavf > 52.23.1, lavc > 52.10.0).
1771
1772 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1773 The old decoding functions are deprecated, all new code should use the
1774 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1775 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1776 argument instead of a const uint8_t *buf / int buf_size pair.
1777
1778 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1779 Introduce the av_fifo_space() function.
1780
1781 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket

1783 libavcodec/avcodec.h.
1784
1785 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1786 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1787 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1788 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1789 PIX_FMT_BGR32_1 are now macros.
1790 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1791 Re-sort the enum PixelFormat list accordingly.
1792 This change breaks API/ABI backward compatibility.
1793
1794 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1795 Add the enum PixelFormat values:
1796 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1797 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1798
1799 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1800 The Mersenne Twister PRNG implemented through the av_random* functions
1801 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1802 instead.
1803
1804 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1805 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1806 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1807 and av_fifo_realloc2.
1808 In addition, the order of the function arguments of av_fifo_generic_read
1809 was changed to match av_fifo_generic_write.
1810 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1811 applications, they may not use sizeof() or directly access members.
1812
1813 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1814 Introduce a new metadata API (see av_metadata_get() and friends).
1815 The old API is now deprecated and should not be used anymore. This especially
1816 includes the following structure fields:
1817 - AVFormatContext.title
1818 - AVFormatContext.author
1819 - AVFormatContext.copyright
1820 - AVFormatContext.comment
1821 - AVFormatContext.album
1822 - AVFormatContext.year
1823 - AVFormatContext.track
1824 - AVFormatContext.genre
1825 - AVStream.language
1826 - AVStream.filename
1827 - AVProgram.provider_name
1828 - AVProgram.name
1829 - AVChapter.title
