15
16 2016-xx-xx - xxxxxxx - lavf 57.3.0 - avformat.h
17 Add AVFormatContext.opaque, io_open and io_close, allowing custom IO
18 for muxers and demuxers that open additional files.
19
20 2015-xx-xx - xxxxxxx - lavc 57.12.0 - avcodec.h
21 Add AVCodecDescriptor.profiles and avcodec_profile_name().
22
23 2015-xx-xx - xxxxxxx - lavc 57.11.0 - avcodec.h dirac.h

32 get image slices before the full frame is encoded any more. The libavformat
33 rtpenc muxer can still be used for RFC-2190 packetization.
34
35 2015-11-xx - xxxxxxx - lavc 57.9.0 - avcodec.h

1719 Add a pts field to AVSubtitle which gives the subtitle packet pts
1720 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1721 not work right without this.
1722
1723 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1724 PKT_FLAG_KEY has been deprecated and will be dropped at the next

1726
1727 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1728 av_lockmgr_register() can be used to register a callback function
1729 that lavc (and in the future, libraries that depend on lavc) can use
1730 to implement mutexes. The application should provide a callback function
1731 that implements the AV_LOCK_* operations described in avcodec.h.
1732 When the lock manager is registered, FFmpeg is guaranteed to behave
1733 correctly in a multi-threaded application.
1734
1735 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1736 av_free_packet() is no longer an inline function. It is now exported.
1737
1738 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1739 Please use NULL instead. This has been supported since r16506
1740 (lavf > 52.23.1, lavc > 52.10.0).
1741
1742 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1743 The old decoding functions are deprecated, all new code should use the
1744 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1745 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1746 argument instead of a const uint8_t *buf / int buf_size pair.
1747
1748 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()

1753 libavcodec/avcodec.h.
1754
1755 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1756 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1757 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1758 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1759 PIX_FMT_BGR32_1 are now macros.
1760 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1761 Re-sort the enum PixelFormat list accordingly.
1762 This change breaks API/ABI backward compatibility.
1763
1764 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1765 Add the enum PixelFormat values:
1766 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1767 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1768
1769 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1770 The Mersenne Twister PRNG implemented through the av_random* functions
1771 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1772 instead.
1773
1774 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1775 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1776 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1777 and av_fifo_realloc2.
1778 In addition, the order of the function arguments of av_fifo_generic_read
1779 was changed to match av_fifo_generic_write.
1780 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1781 applications, they may not use sizeof() or directly access members.
1782
1783 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1784 Introduce a new metadata API (see av_metadata_get() and friends).
1785 The old API is now deprecated and should not be used anymore. This especially
1786 includes the following structure fields:
1787 - AVFormatContext.title
1788 - AVFormatContext.author
1789 - AVFormatContext.copyright
1790 - AVFormatContext.comment
1791 - AVFormatContext.album
1792 - AVFormatContext.year
1793 - AVFormatContext.track
1794 - AVFormatContext.genre
1795 - AVStream.language
1796 - AVStream.filename
1797 - AVProgram.provider_name
1798 - AVProgram.name
1799 - AVChapter.title
