400 Add avcodec_free_frame(). This function must now
401 be used for freeing an AVFrame.
403 2012-09-12 - e3e09f2 / 8919fee - lavu 51.73.100 / 51.41.0 - audioconvert.h

426 2012-08-07 - 7a72695 / 104e10f - lavc 54.51.100 / 54.25.0 - avcodec.h
427 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
428 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
429 Note that this can break user code that includes avcodec.h and uses the
430 'CodecID' identifier. Such code should either #undef CodecID or stop using the

484 For audio formats with fixed frame size, the last frame
485 no longer needs to be padded with silence, libavcodec
486 will handle this internally (effectively all encoders
487 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

1585 Change the avfilter_add_colorspace() signature, make it accept an
1586 (AVFilterFormats **) rather than an (AVFilterFormats *) as before.
1588 2010-01-03 - 4fd1f18 - lavfi 1.13.0 - avfilter_add_colorspace()

1591 2010-01-02 - 8eb631f - lavf 52.46.0 - av_match_ext()

1613 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
1614 Remove the next field from AVFilter, this is not anymore required.
1616 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1617 Introduce the avfilter_next() function.
1619 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1620 Change the signature of avfilter_register() to make it return an
1621 int. This is required since now the registration operation may fail.
1623 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1624 Make the pixdesc.h API public.
1626 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1627 Add a next field to AVFilter, this is used for simplifying the
1628 registration and management of the registered filters.
1630 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
1631 Add a description field to AVFilter.
1633 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1634 Change the interface of avfilter_make_format_list() from

1638 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
1639 Make avfilter_get_video_buffer() recursive and add the w and h
1642 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
1643 Add w and h fields to AVFilterPic.
1645 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1646 This is now an unsigned int instead of a signed int.
1648 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1649 Add a pts field to AVSubtitle which gives the subtitle packet pts
1650 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1651 not work right without this.
1653 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1654 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1655 major version. Use AV_PKT_FLAG_KEY instead.
1657 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1658 av_lockmgr_register() can be used to register a callback function
1659 that lavc (and in the future, libraries that depend on lavc) can use
1660 to implement mutexes. The application should provide a callback function
1661 that implements the AV_LOCK_* operations described in avcodec.h.
1662 When the lock manager is registered, FFmpeg is guaranteed to behave
1663 correctly in a multi-threaded application.
1665 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1666 av_free_packet() is no longer an inline function. It is now exported.
1668 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1669 Please use NULL instead. This has been supported since r16506
1670 (lavf > 52.23.1, lavc > 52.10.0).
1672 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1673 The old decoding functions are deprecated, all new code should use the
1674 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1675 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1676 argument instead of a const uint8_t *buf / int buf_size pair.
1678 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1679 Introduce the av_fifo_space() function.
1681 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1682 Move AVPacket declaration from libavformat/avformat.h to
1683 libavcodec/avcodec.h.
1685 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1686 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1687 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1688 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1689 PIX_FMT_BGR32_1 are now macros.
1690 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1691 Re-sort the enum PixelFormat list accordingly.
1692 This change breaks API/ABI backward compatibility.
1694 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1695 Add the enum PixelFormat values:
1696 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1697 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1699 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1700 The Mersenne Twister PRNG implemented through the av_random* functions
1701 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1704 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1705 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1706 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1707 and av_fifo_realloc2.
1708 In addition, the order of the function arguments of av_fifo_generic_read
1709 was changed to match av_fifo_generic_write.
1710 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1711 applications, they may not use sizeof() or directly access members.
1713 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1714 Introduce a new metadata API (see av_metadata_get() and friends).
1715 The old API is now deprecated and should not be used anymore. This especially
1716 includes the following structure fields:
1717 - AVFormatContext.title
1718 - AVFormatContext.author
1719 - AVFormatContext.copyright
1720 - AVFormatContext.comment
1721 - AVFormatContext.album
1722 - AVFormatContext.year
1723 - AVFormatContext.track
1724 - AVFormatContext.genre
1727 - AVProgram.provider_name
