1683 Introduce the avfilter_next() function.
1684
1685 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1686 Change the signature of avfilter_register() to make it return an

1690 Make the pixdesc.h API public.

1713
1714 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1715 Add a pts field to AVSubtitle which gives the subtitle packet pts
1716 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1717 not work right without this.
1718
1719 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1720 PKT_FLAG_KEY has been deprecated and will be dropped at the next

1722
1723 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1724 av_lockmgr_register() can be used to register a callback function
1725 that lavc (and in the future, libraries that depend on lavc) can use
1726 to implement mutexes. The application should provide a callback function
1727 that implements the AV_LOCK_* operations described in avcodec.h.
1728 When the lock manager is registered, FFmpeg is guaranteed to behave
1729 correctly in a multi-threaded application.
1730
1731 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1732 av_free_packet() is no longer an inline function. It is now exported.
1733
1734 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1735 Please use NULL instead. This has been supported since r16506
1736 (lavf > 52.23.1, lavc > 52.10.0).
1737
1738 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1739 The old decoding functions are deprecated, all new code should use the
1740 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1741 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1742 argument instead of a const uint8_t *buf / int buf_size pair.
1743
1744 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1745 Introduce the av_fifo_space() function.
1746

1749 libavcodec/avcodec.h.
1750
1751 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1752 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1753 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1754 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1755 PIX_FMT_BGR32_1 are now macros.
1756 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1757 Re-sort the enum PixelFormat list accordingly.
1758 This change breaks API/ABI backward compatibility.
1759
1760 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1761 Add the enum PixelFormat values:
1762 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1763 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1764
1765 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1766 The Mersenne Twister PRNG implemented through the av_random* functions
1767 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1768 instead.
1769
1770 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1771 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1772 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1773 and av_fifo_realloc2.
1774 In addition, the order of the function arguments of av_fifo_generic_read
1775 was changed to match av_fifo_generic_write.
1776 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1777 applications, they may not use sizeof() or directly access members.
1778
1779 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1780 Introduce a new metadata API (see av_metadata_get() and friends).
1781 The old API is now deprecated and should not be used anymore. This especially
1782 includes the following structure fields:
1783 - AVFormatContext.title
1784 - AVFormatContext.author
1785 - AVFormatContext.copyright
1786 - AVFormatContext.comment
1787 - AVFormatContext.album
1788 - AVFormatContext.year
1789 - AVFormatContext.track
1790 - AVFormatContext.genre
1791 - AVStream.language
1792 - AVStream.filename
1793 - AVProgram.provider_name
1794 - AVProgram.name
1795 - AVChapter.title
