434 'CodecID' identifier. Such code should either #undef CodecID or stop using the

1589 Change the avfilter_add_colorspace() signature, make it accept an
1590 (AVFilterFormats **) rather than an (AVFilterFormats *) as before.
1592 2010-01-03 - 4fd1f18 - lavfi 1.13.0 - avfilter_add_colorspace()

1595 2010-01-02 - 8eb631f - lavf 52.46.0 - av_match_ext()

1602 Add av_metadata_set2(), AV_METADATA_DONT_STRDUP_KEY and
1603 AV_METADATA_DONT_STRDUP_VAL.
1605 2009-12-13 - 277c733 - lavu 50.7.0 - avstring.h API

1617 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
1618 Remove the next field from AVFilter, this is not anymore required.
1620 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1621 Introduce the avfilter_next() function.
1623 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1624 Change the signature of avfilter_register() to make it return an
1625 int. This is required since now the registration operation may fail.
1627 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1628 Make the pixdesc.h API public.
1630 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1631 Add a next field to AVFilter, this is used for simplifying the
1632 registration and management of the registered filters.
1634 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
1635 Add a description field to AVFilter.
1637 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1638 Change the interface of avfilter_make_format_list() from

1642 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
1643 Make avfilter_get_video_buffer() recursive and add the w and h
1646 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
1647 Add w and h fields to AVFilterPic.
1649 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1650 This is now an unsigned int instead of a signed int.
1652 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1653 Add a pts field to AVSubtitle which gives the subtitle packet pts
1654 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1655 not work right without this.
1657 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1658 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1659 major version. Use AV_PKT_FLAG_KEY instead.
1661 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1662 av_lockmgr_register() can be used to register a callback function
1663 that lavc (and in the future, libraries that depend on lavc) can use
1664 to implement mutexes. The application should provide a callback function
1665 that implements the AV_LOCK_* operations described in avcodec.h.
1666 When the lock manager is registered, FFmpeg is guaranteed to behave
1667 correctly in a multi-threaded application.
1669 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1670 av_free_packet() is no longer an inline function. It is now exported.
1672 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1673 Please use NULL instead. This has been supported since r16506
1674 (lavf > 52.23.1, lavc > 52.10.0).
1676 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1677 The old decoding functions are deprecated, all new code should use the
1678 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1679 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1680 argument instead of a const uint8_t *buf / int buf_size pair.
1682 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1683 Introduce the av_fifo_space() function.
1685 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1686 Move AVPacket declaration from libavformat/avformat.h to
1687 libavcodec/avcodec.h.
1689 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1690 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1691 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1692 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1693 PIX_FMT_BGR32_1 are now macros.
1694 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1695 Re-sort the enum PixelFormat list accordingly.
1696 This change breaks API/ABI backward compatibility.
1698 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1699 Add the enum PixelFormat values:
1700 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1701 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1703 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1704 The Mersenne Twister PRNG implemented through the av_random* functions
1705 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1708 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1709 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1710 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1711 and av_fifo_realloc2.
1712 In addition, the order of the function arguments of av_fifo_generic_read
1713 was changed to match av_fifo_generic_write.
1714 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1715 applications, they may not use sizeof() or directly access members.
1717 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1718 Introduce a new metadata API (see av_metadata_get() and friends).
1719 The old API is now deprecated and should not be used anymore. This especially
1720 includes the following structure fields:
1721 - AVFormatContext.title
1722 - AVFormatContext.author
1723 - AVFormatContext.copyright
1724 - AVFormatContext.comment
1725 - AVFormatContext.album
1726 - AVFormatContext.year
1727 - AVFormatContext.track
1728 - AVFormatContext.genre
1731 - AVProgram.provider_name
