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:

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

598 'PixelFormat' identifier. Such code should either #undef PixelFormat
599 or stop using the PixelFormat name.

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

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

846 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
847 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
848 avcodec_decode_audio4() writes output samples to an AVFrame, which allows
849 audio decoders to use get_buffer().
851 2011-12-04 - 560f773 - lavc 53.24.0
852 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1677 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1678 Make the pixdesc.h API public.
1680 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1681 Add a next field to AVFilter, this is used for simplifying the
1682 registration and management of the registered filters.
1684 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
1685 Add a description field to AVFilter.
1687 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1688 Change the interface of avfilter_make_format_list() from
1689 avfilter_make_format_list(int n, ...) to
1690 avfilter_make_format_list(enum PixelFormat *pix_fmts).
1692 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
1693 Make avfilter_get_video_buffer() recursive and add the w and h
1696 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
1697 Add w and h fields to AVFilterPic.
1699 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1700 This is now an unsigned int instead of a signed int.
1702 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1703 Add a pts field to AVSubtitle which gives the subtitle packet pts
1704 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1705 not work right without this.
1707 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1708 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1709 major version. Use AV_PKT_FLAG_KEY instead.
1711 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1712 av_lockmgr_register() can be used to register a callback function
1713 that lavc (and in the future, libraries that depend on lavc) can use
1714 to implement mutexes. The application should provide a callback function
1715 that implements the AV_LOCK_* operations described in avcodec.h.
1716 When the lock manager is registered, FFmpeg is guaranteed to behave
1717 correctly in a multi-threaded application.
1719 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1720 av_free_packet() is no longer an inline function. It is now exported.
1722 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1723 Please use NULL instead. This has been supported since r16506
1724 (lavf > 52.23.1, lavc > 52.10.0).
1726 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1727 The old decoding functions are deprecated, all new code should use the
1728 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1729 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1730 argument instead of a const uint8_t *buf / int buf_size pair.
1732 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1733 Introduce the av_fifo_space() function.
1735 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1736 Move AVPacket declaration from libavformat/avformat.h to
1737 libavcodec/avcodec.h.
1739 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1740 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1741 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1742 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1743 PIX_FMT_BGR32_1 are now macros.
1744 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1745 Re-sort the enum PixelFormat list accordingly.
1746 This change breaks API/ABI backward compatibility.
1748 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1749 Add the enum PixelFormat values:
1750 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1751 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1753 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1754 The Mersenne Twister PRNG implemented through the av_random* functions
1755 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1758 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1759 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1760 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1761 and av_fifo_realloc2.
1762 In addition, the order of the function arguments of av_fifo_generic_read
1763 was changed to match av_fifo_generic_write.
1764 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1765 applications, they may not use sizeof() or directly access members.
1767 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1768 Introduce a new metadata API (see av_metadata_get() and friends).
1769 The old API is now deprecated and should not be used anymore. This especially
1770 includes the following structure fields:
1771 - AVFormatContext.title
1772 - AVFormatContext.author
1773 - AVFormatContext.copyright
1774 - AVFormatContext.comment
1775 - AVFormatContext.album
1776 - AVFormatContext.year
1777 - AVFormatContext.track
1778 - AVFormatContext.genre
1781 - AVProgram.provider_name
