1652 Introduce the avfilter_next() function.
1653
1654 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1655 Change the signature of avfilter_register() to make it return an

1659 Make the pixdesc.h API public.

1682
1683 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1684 Add a pts field to AVSubtitle which gives the subtitle packet pts
1685 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1686 not work right without this.
1687
1688 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1689 PKT_FLAG_KEY has been deprecated and will be dropped at the next

1691
1692 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1693 av_lockmgr_register() can be used to register a callback function
1694 that lavc (and in the future, libraries that depend on lavc) can use
1695 to implement mutexes. The application should provide a callback function
1696 that implements the AV_LOCK_* operations described in avcodec.h.
1697 When the lock manager is registered, FFmpeg is guaranteed to behave
1698 correctly in a multi-threaded application.
1699
1700 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1701 av_free_packet() is no longer an inline function. It is now exported.
1702
1703 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1704 Please use NULL instead. This has been supported since r16506
1705 (lavf > 52.23.1, lavc > 52.10.0).
1706
1707 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1708 The old decoding functions are deprecated, all new code should use the
1709 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1710 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1711 argument instead of a const uint8_t *buf / int buf_size pair.
1712
1713 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1714 Introduce the av_fifo_space() function.
1715
1716 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1717 Move AVPacket declaration from libavformat/avformat.h to
1718 libavcodec/avcodec.h.
1719
1720 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1721 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1722 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1723 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1724 PIX_FMT_BGR32_1 are now macros.
1725 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1726 Re-sort the enum PixelFormat list accordingly.
1727 This change breaks API/ABI backward compatibility.
1728
1729 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1730 Add the enum PixelFormat values:
1731 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1732 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1733
1734 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1735 The Mersenne Twister PRNG implemented through the av_random* functions
1736 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1737 instead.
1738
1739 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1740 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1741 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1742 and av_fifo_realloc2.
1743 In addition, the order of the function arguments of av_fifo_generic_read
1744 was changed to match av_fifo_generic_write.
1745 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1746 applications, they may not use sizeof() or directly access members.
1747
1748 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1749 Introduce a new metadata API (see av_metadata_get() and friends).
1750 The old API is now deprecated and should not be used anymore. This especially
1751 includes the following structure fields:
1752 - AVFormatContext.title
1753 - AVFormatContext.author
1754 - AVFormatContext.copyright
1755 - AVFormatContext.comment
1756 - AVFormatContext.album
1757 - AVFormatContext.year
1758 - AVFormatContext.track
1759 - AVFormatContext.genre
1760 - AVStream.language
1761 - AVStream.filename
1762 - AVProgram.provider_name
1763 - AVProgram.name
1764 - AVChapter.title
