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:
6 libavdevice: 2015-08-28
7 libavfilter: 2015-08-28
8 libavformat: 2015-08-28
9 libavresample: 2015-08-28

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

603 'PixelFormat' identifier. Such code should either #undef PixelFormat
604 or stop using the PixelFormat name.

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

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

851 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
852 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
853 avcodec_decode_audio4() writes output samples to an AVFrame, which allows

1676 Introduce the avfilter_next() function.
1678 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1679 Change the signature of avfilter_register() to make it return an
1680 int. This is required since now the registration operation may fail.
1682 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1683 Make the pixdesc.h API public.
1685 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1686 Add a next field to AVFilter, this is used for simplifying the
1687 registration and management of the registered filters.
1689 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
1690 Add a description field to AVFilter.
1692 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1693 Change the interface of avfilter_make_format_list() from
1694 avfilter_make_format_list(int n, ...) to
1695 avfilter_make_format_list(enum PixelFormat *pix_fmts).
1697 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
1698 Make avfilter_get_video_buffer() recursive and add the w and h
1701 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
1702 Add w and h fields to AVFilterPic.
1704 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1705 This is now an unsigned int instead of a signed int.
1707 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1708 Add a pts field to AVSubtitle which gives the subtitle packet pts
1709 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1710 not work right without this.
1712 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1713 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1714 major version. Use AV_PKT_FLAG_KEY instead.
1716 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1717 av_lockmgr_register() can be used to register a callback function
1718 that lavc (and in the future, libraries that depend on lavc) can use
1719 to implement mutexes. The application should provide a callback function
1720 that implements the AV_LOCK_* operations described in avcodec.h.
1721 When the lock manager is registered, FFmpeg is guaranteed to behave
1722 correctly in a multi-threaded application.
1724 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1725 av_free_packet() is no longer an inline function. It is now exported.
1727 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1728 Please use NULL instead. This has been supported since r16506
1729 (lavf > 52.23.1, lavc > 52.10.0).
1731 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1732 The old decoding functions are deprecated, all new code should use the
1733 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1734 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1735 argument instead of a const uint8_t *buf / int buf_size pair.
1737 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1738 Introduce the av_fifo_space() function.
1740 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1741 Move AVPacket declaration from libavformat/avformat.h to
1742 libavcodec/avcodec.h.
1744 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1745 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1746 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1747 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1748 PIX_FMT_BGR32_1 are now macros.
1749 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1750 Re-sort the enum PixelFormat list accordingly.
1751 This change breaks API/ABI backward compatibility.
1753 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1754 Add the enum PixelFormat values:
1755 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1756 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1758 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1759 The Mersenne Twister PRNG implemented through the av_random* functions
1760 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1763 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1764 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1765 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1766 and av_fifo_realloc2.
1767 In addition, the order of the function arguments of av_fifo_generic_read
1768 was changed to match av_fifo_generic_write.
1769 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1770 applications, they may not use sizeof() or directly access members.
1772 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1773 Introduce a new metadata API (see av_metadata_get() and friends).
1774 The old API is now deprecated and should not be used anymore. This especially
1775 includes the following structure fields:
1776 - AVFormatContext.title
1777 - AVFormatContext.author
1778 - AVFormatContext.copyright
1779 - AVFormatContext.comment
1780 - AVFormatContext.album
1781 - AVFormatContext.year
1782 - AVFormatContext.track
1783 - AVFormatContext.genre
1786 - AVProgram.provider_name
