401 Note that this can break user code that includes pixfmt.h and uses the
402 'PixelFormat' identifier. Such code should either #undef PixelFormat
403 or stop using the PixelFormat name.
405 2012-10-05 - 55c49af / e7ba5b1 - lavr 1.0.0 - avresample.h

438 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
439 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
440 Note that this can break user code that includes avcodec.h and uses the
441 'CodecID' identifier. Such code should either #undef CodecID or stop using the

495 For audio formats with fixed frame size, the last frame
496 no longer needs to be padded with silence, libavcodec
497 will handle this internally (effectively all encoders

1596 Change the avfilter_add_colorspace() signature, make it accept an
1597 (AVFilterFormats **) rather than an (AVFilterFormats *) as before.
1599 2010-01-03 - 4fd1f18 - lavfi 1.13.0 - avfilter_add_colorspace()
1600 Add avfilter_add_colorspace().
1602 2010-01-02 - 8eb631f - lavf 52.46.0 - av_match_ext()
1603 Add av_match_ext(), it should be used in place of match_ext().
1605 2010-01-01 - a1f547b - lavf 52.45.0 - av_guess_format()
1606 Add av_guess_format(), it should be used in place of guess_format().

1609 Add av_metadata_set2(), AV_METADATA_DONT_STRDUP_KEY and
1610 AV_METADATA_DONT_STRDUP_VAL.
1612 2009-12-13 - 277c733 - lavu 50.7.0 - avstring.h API

1621 2009-12-05 - a13a543 - lavfi 1.12.0 - avfilter_draw_slice()
1622 Add a slice_dir parameter to avfilter_draw_slice().
1624 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
1625 Remove the next field from AVFilter, this is not anymore required.
1627 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1628 Introduce the avfilter_next() function.
1630 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1631 Change the signature of avfilter_register() to make it return an
1632 int. This is required since now the registration operation may fail.
1634 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1635 Make the pixdesc.h API public.
1637 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

1639 registration and management of the registered filters.
1641 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
1642 Add a description field to AVFilter.
1644 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1645 Change the interface of avfilter_make_format_list() from

1649 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
1650 Make avfilter_get_video_buffer() recursive and add the w and h
1653 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
1654 Add w and h fields to AVFilterPic.
1656 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1657 This is now an unsigned int instead of a signed int.
1659 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1660 Add a pts field to AVSubtitle which gives the subtitle packet pts
1661 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1662 not work right without this.
1664 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1665 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1666 major version. Use AV_PKT_FLAG_KEY instead.
1668 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1669 av_lockmgr_register() can be used to register a callback function
1670 that lavc (and in the future, libraries that depend on lavc) can use
1671 to implement mutexes. The application should provide a callback function
1672 that implements the AV_LOCK_* operations described in avcodec.h.
1673 When the lock manager is registered, FFmpeg is guaranteed to behave
1674 correctly in a multi-threaded application.
1676 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1677 av_free_packet() is no longer an inline function. It is now exported.
1679 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1680 Please use NULL instead. This has been supported since r16506
1681 (lavf > 52.23.1, lavc > 52.10.0).
1683 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1684 The old decoding functions are deprecated, all new code should use the
1685 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1686 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1687 argument instead of a const uint8_t *buf / int buf_size pair.
1689 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1690 Introduce the av_fifo_space() function.
1692 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1693 Move AVPacket declaration from libavformat/avformat.h to
1694 libavcodec/avcodec.h.
1696 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1697 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1698 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1699 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1700 PIX_FMT_BGR32_1 are now macros.
1701 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1702 Re-sort the enum PixelFormat list accordingly.
1703 This change breaks API/ABI backward compatibility.
1705 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1706 Add the enum PixelFormat values:
1707 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1708 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1710 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1711 The Mersenne Twister PRNG implemented through the av_random* functions
1712 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1715 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1716 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1717 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1718 and av_fifo_realloc2.
1719 In addition, the order of the function arguments of av_fifo_generic_read
1720 was changed to match av_fifo_generic_write.
1721 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1722 applications, they may not use sizeof() or directly access members.
1724 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1725 Introduce a new metadata API (see av_metadata_get() and friends).
1726 The old API is now deprecated and should not be used anymore. This especially
1727 includes the following structure fields:
1728 - AVFormatContext.title
1729 - AVFormatContext.author
1730 - AVFormatContext.copyright
1731 - AVFormatContext.comment
1732 - AVFormatContext.album
1733 - AVFormatContext.year
1734 - AVFormatContext.track
1735 - AVFormatContext.genre
1738 - AVProgram.provider_name
