1 Never assume the API of libav* to be stable unless at least 1 month has passed
2 since the last major version increase.
4 The last version increases were:

7 libavfilter: 2015-08-28
8 libavformat: 2015-08-28
9 libavresample: 2015-08-28
10 libswscale: 2015-08-28

602 To provide backwards compatibility, PixelFormat is now #defined as

605 'PixelFormat' identifier. Such code should either #undef PixelFormat
606 or stop using the PixelFormat name.

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

828 e1d9dbf Add a new installed header - buffersrc.h
829 It contains a new function av_buffersrc_buffer() that allows passing
830 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
831 it allows for direct rendering.

853 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
854 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().

1678 Introduce the avfilter_next() function.
1680 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1681 Change the signature of avfilter_register() to make it return an
1682 int. This is required since now the registration operation may fail.
1684 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1685 Make the pixdesc.h API public.
1687 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1688 Add a next field to AVFilter, this is used for simplifying the
1689 registration and management of the registered filters.
1691 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
1692 Add a description field to AVFilter.
1694 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1695 Change the interface of avfilter_make_format_list() from
1696 avfilter_make_format_list(int n, ...) to
1697 avfilter_make_format_list(enum PixelFormat *pix_fmts).
1699 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
1700 Make avfilter_get_video_buffer() recursive and add the w and h
1703 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
1704 Add w and h fields to AVFilterPic.
1706 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1707 This is now an unsigned int instead of a signed int.
1709 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1710 Add a pts field to AVSubtitle which gives the subtitle packet pts
1711 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1712 not work right without this.
1714 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1715 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1716 major version. Use AV_PKT_FLAG_KEY instead.
1718 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1719 av_lockmgr_register() can be used to register a callback function
1720 that lavc (and in the future, libraries that depend on lavc) can use
1721 to implement mutexes. The application should provide a callback function
1722 that implements the AV_LOCK_* operations described in avcodec.h.
1723 When the lock manager is registered, FFmpeg is guaranteed to behave
1724 correctly in a multi-threaded application.
1726 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1727 av_free_packet() is no longer an inline function. It is now exported.
1729 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1730 Please use NULL instead. This has been supported since r16506
1731 (lavf > 52.23.1, lavc > 52.10.0).
1733 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1734 The old decoding functions are deprecated, all new code should use the
1735 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1736 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1737 argument instead of a const uint8_t *buf / int buf_size pair.
1739 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1740 Introduce the av_fifo_space() function.
1742 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1743 Move AVPacket declaration from libavformat/avformat.h to
1744 libavcodec/avcodec.h.
1746 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1747 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1748 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1749 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1750 PIX_FMT_BGR32_1 are now macros.
1751 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1752 Re-sort the enum PixelFormat list accordingly.
1753 This change breaks API/ABI backward compatibility.
1755 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1756 Add the enum PixelFormat values:
1757 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1758 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1760 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1761 The Mersenne Twister PRNG implemented through the av_random* functions
1762 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1765 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1766 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1767 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1768 and av_fifo_realloc2.
1769 In addition, the order of the function arguments of av_fifo_generic_read
1770 was changed to match av_fifo_generic_write.
1771 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1772 applications, they may not use sizeof() or directly access members.
1774 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1775 Introduce a new metadata API (see av_metadata_get() and friends).
1776 The old API is now deprecated and should not be used anymore. This especially
1777 includes the following structure fields:
1778 - AVFormatContext.title
1779 - AVFormatContext.author
1780 - AVFormatContext.copyright
1781 - AVFormatContext.comment
1782 - AVFormatContext.album
1783 - AVFormatContext.year
1784 - AVFormatContext.track
1785 - AVFormatContext.genre
1788 - AVProgram.provider_name
