1522 enum PixelFormat *format -> int format in AVFilterLink
1523
1524 Change the function signatures:

1526 AVFilterFormats *avfilter_make_format_list(const int *fmts);
1527
1528 int avfilter_add_colorspace(AVFilterFormats **avff, enum PixelFormat pix_fmt); ->
1529 int avfilter_add_format (AVFilterFormats **avff, int fmt);
1530
1531 AVFilterFormats *avfilter_all_colorspaces(void); ->
1532 AVFilterFormats *avfilter_all_formats (enum AVMediaType type);

1731 Make the pixdesc.h API public.
1732
1733 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1734 Add a next field to AVFilter, this is used for simplifying the
1735 registration and management of the registered filters.

1754
1755 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1756 Add a pts field to AVSubtitle which gives the subtitle packet pts
1757 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1758 not work right without this.
1759
1760 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1761 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1762 major version. Use AV_PKT_FLAG_KEY instead.
1763
1764 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1765 av_lockmgr_register() can be used to register a callback function
1766 that lavc (and in the future, libraries that depend on lavc) can use
1767 to implement mutexes. The application should provide a callback function
1768 that implements the AV_LOCK_* operations described in avcodec.h.
1769 When the lock manager is registered, FFmpeg is guaranteed to behave
1770 correctly in a multi-threaded application.
1771
1772 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1773 av_free_packet() is no longer an inline function. It is now exported.
1774
1775 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1776 Please use NULL instead. This has been supported since r16506
1777 (lavf > 52.23.1, lavc > 52.10.0).
1778
1779 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1780 The old decoding functions are deprecated, all new code should use the
1781 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1782 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1783 argument instead of a const uint8_t *buf / int buf_size pair.
1784
1785 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1786 Introduce the av_fifo_space() function.
1787

1790 libavcodec/avcodec.h.
1791
1792 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1793 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1794 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1795 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1796 PIX_FMT_BGR32_1 are now macros.
1797 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1798 Re-sort the enum PixelFormat list accordingly.
1799 This change breaks API/ABI backward compatibility.
1800
1801 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1802 Add the enum PixelFormat values:
1803 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1804 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1805
1806 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1807 The Mersenne Twister PRNG implemented through the av_random* functions
1808 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1809 instead.
1810
1811 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1812 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1813 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1814 and av_fifo_realloc2.
1815 In addition, the order of the function arguments of av_fifo_generic_read
1816 was changed to match av_fifo_generic_write.
1817 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1818 applications, they may not use sizeof() or directly access members.
1819
1820 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1821 Introduce a new metadata API (see av_metadata_get() and friends).
1822 The old API is now deprecated and should not be used anymore. This especially
1823 includes the following structure fields:
1824 - AVFormatContext.title
1825 - AVFormatContext.author
1826 - AVFormatContext.copyright
1827 - AVFormatContext.comment
1828 - AVFormatContext.album
1829 - AVFormatContext.year
1830 - AVFormatContext.track
1831 - AVFormatContext.genre
1832 - AVStream.language
1833 - AVStream.filename
1834 - AVProgram.provider_name
1835 - AVProgram.name
1836 - AVChapter.title
