20 Deprecate rtp_callback without replacement, i.e. it won't be possible to
21 get image slices before the full frame is encoded any more. The libavformat
22 rtpenc muxer can still be used for RFC-2190 packetization.
23
24 2015-11-xx - xxxxxxx - lavc 57.9.0 - avcodec.h
25 Add AV_PKT_DATA_FALLBACK_TRACK for making fallback associations between
26 streams.

43 Use av_packet_ref() to make a non-refcounted AVPacket refcounted.

1675
1676 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1677 Change the signature of avfilter_register() to make it return an

1681 Make the pixdesc.h API public.

1704
1705 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1706 Add a pts field to AVSubtitle which gives the subtitle packet pts
1707 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1708 not work right without this.
1709
1710 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1711 PKT_FLAG_KEY has been deprecated and will be dropped at the next

1713
1714 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1715 av_lockmgr_register() can be used to register a callback function
1716 that lavc (and in the future, libraries that depend on lavc) can use
1717 to implement mutexes. The application should provide a callback function
1718 that implements the AV_LOCK_* operations described in avcodec.h.
1719 When the lock manager is registered, FFmpeg is guaranteed to behave
1720 correctly in a multi-threaded application.
1721
1722 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1723 av_free_packet() is no longer an inline function. It is now exported.
1724
1725 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1726 Please use NULL instead. This has been supported since r16506
1727 (lavf > 52.23.1, lavc > 52.10.0).
1728
1729 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1730 The old decoding functions are deprecated, all new code should use the
1731 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1732 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1733 argument instead of a const uint8_t *buf / int buf_size pair.
1734
1735 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()

1740 libavcodec/avcodec.h.
1741
1742 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1743 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1744 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1745 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1746 PIX_FMT_BGR32_1 are now macros.
1747 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1748 Re-sort the enum PixelFormat list accordingly.
1749 This change breaks API/ABI backward compatibility.
1750
1751 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1752 Add the enum PixelFormat values:
1753 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1754 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1755
1756 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1757 The Mersenne Twister PRNG implemented through the av_random* functions
1758 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1759 instead.
1760
1761 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1762 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1763 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1764 and av_fifo_realloc2.
1765 In addition, the order of the function arguments of av_fifo_generic_read
1766 was changed to match av_fifo_generic_write.
1767 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1768 applications, they may not use sizeof() or directly access members.
1769
1770 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1771 Introduce a new metadata API (see av_metadata_get() and friends).
1772 The old API is now deprecated and should not be used anymore. This especially
1773 includes the following structure fields:
1774 - AVFormatContext.title
1775 - AVFormatContext.author
1776 - AVFormatContext.copyright
1777 - AVFormatContext.comment
1778 - AVFormatContext.album
1779 - AVFormatContext.year
1780 - AVFormatContext.track
1781 - AVFormatContext.genre
1782 - AVStream.language
1783 - AVStream.filename
1784 - AVProgram.provider_name
1785 - AVProgram.name
1786 - AVChapter.title
