1686 2010-01-02 - 8eb631f - lavf 52.46.0 - av_match_ext()
1687 Add av_match_ext(), it should be used in place of match_ext().
1689 2010-01-01 - a1f547b - lavf 52.45.0 - av_guess_format()
1690 Add av_guess_format(), it should be used in place of guess_format().
1692 2009-12-13 - a181981 - lavf 52.43.0 - metadata API
1693 Add av_metadata_set2(), AV_METADATA_DONT_STRDUP_KEY and
1694 AV_METADATA_DONT_STRDUP_VAL.
1696 2009-12-13 - 277c733 - lavu 50.7.0 - avstring.h API

1703 Introduce the av_bmg_next() function.
1705 2009-12-05 - a13a543 - lavfi 1.12.0 - avfilter_draw_slice()
1706 Add a slice_dir parameter to avfilter_draw_slice().
1708 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
1709 Remove the next field from AVFilter, this is not anymore required.
1711 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1712 Introduce the avfilter_next() function.
1714 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1715 Change the signature of avfilter_register() to make it return an
1716 int. This is required since now the registration operation may fail.
1718 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1719 Make the pixdesc.h API public.
1721 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1722 Add a next field to AVFilter, this is used for simplifying the
1723 registration and management of the registered filters.
1725 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
1726 Add a description field to AVFilter.
1728 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1729 Change the interface of avfilter_make_format_list() from

1733 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
1734 Make avfilter_get_video_buffer() recursive and add the w and h
1737 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
1738 Add w and h fields to AVFilterPic.
1740 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1741 This is now an unsigned int instead of a signed int.
1743 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1744 Add a pts field to AVSubtitle which gives the subtitle packet pts
1745 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1746 not work right without this.
1748 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1749 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1750 major version. Use AV_PKT_FLAG_KEY instead.
1752 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1753 av_lockmgr_register() can be used to register a callback function
1754 that lavc (and in the future, libraries that depend on lavc) can use
1755 to implement mutexes. The application should provide a callback function
1756 that implements the AV_LOCK_* operations described in avcodec.h.
1757 When the lock manager is registered, FFmpeg is guaranteed to behave
1758 correctly in a multi-threaded application.
1760 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1761 av_free_packet() is no longer an inline function. It is now exported.
1763 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1764 Please use NULL instead. This has been supported since r16506
1765 (lavf > 52.23.1, lavc > 52.10.0).
1767 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1768 The old decoding functions are deprecated, all new code should use the
1769 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1770 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1771 argument instead of a const uint8_t *buf / int buf_size pair.
1773 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1774 Introduce the av_fifo_space() function.
1776 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1777 Move AVPacket declaration from libavformat/avformat.h to
1778 libavcodec/avcodec.h.
1780 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1781 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1782 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1783 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1784 PIX_FMT_BGR32_1 are now macros.
1785 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1786 Re-sort the enum PixelFormat list accordingly.
1787 This change breaks API/ABI backward compatibility.
1789 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1790 Add the enum PixelFormat values:
1791 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1792 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1794 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1795 The Mersenne Twister PRNG implemented through the av_random* functions
1796 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1799 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1800 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1801 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1802 and av_fifo_realloc2.
1803 In addition, the order of the function arguments of av_fifo_generic_read
1804 was changed to match av_fifo_generic_write.
1805 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1806 applications, they may not use sizeof() or directly access members.
1808 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1809 Introduce a new metadata API (see av_metadata_get() and friends).
1810 The old API is now deprecated and should not be used anymore. This especially
1811 includes the following structure fields:
1812 - AVFormatContext.title
1813 - AVFormatContext.author
1814 - AVFormatContext.copyright
1815 - AVFormatContext.comment
1816 - AVFormatContext.album
1817 - AVFormatContext.year
1818 - AVFormatContext.track
1819 - AVFormatContext.genre
1822 - AVProgram.provider_name
