563 To provide backwards compatibility, PixelFormat is now #defined as
565 Note that this can break user code that includes pixfmt.h and uses the
566 'PixelFormat' identifier. Such code should either #undef PixelFormat
567 or stop using the PixelFormat name.

670 For audio formats with fixed frame size, the last frame
671 no longer needs to be padded with silence, libavcodec
672 will handle this internally (effectively all encoders
673 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).
675 2012-05-07 - 828bd08 - lavc 54.13.0 - avcodec.h

789 e1d9dbf Add a new installed header - buffersrc.h
790 It contains a new function av_buffersrc_buffer() that allows passing
791 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
792 it allows for direct rendering.
793 1c9e340 Add avfilter_copy_frame_props() for copying properties from

814 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
815 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().

817 audio decoders to use get_buffer().
819 2011-12-04 - 560f773 - lavc 53.24.0
820 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1684 When the lock manager is registered, FFmpeg is guaranteed to behave
1685 correctly in a multi-threaded application.
1687 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1688 av_free_packet() is no longer an inline function. It is now exported.
1690 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1691 Please use NULL instead. This has been supported since r16506
1692 (lavf > 52.23.1, lavc > 52.10.0).
1694 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1695 The old decoding functions are deprecated, all new code should use the
1696 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1697 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1698 argument instead of a const uint8_t *buf / int buf_size pair.
1700 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1701 Introduce the av_fifo_space() function.
1703 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1704 Move AVPacket declaration from libavformat/avformat.h to
1705 libavcodec/avcodec.h.
1707 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1708 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1709 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1710 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1711 PIX_FMT_BGR32_1 are now macros.
1712 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1713 Re-sort the enum PixelFormat list accordingly.
1714 This change breaks API/ABI backward compatibility.
1716 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1717 Add the enum PixelFormat values:
1718 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1719 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1721 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1722 The Mersenne Twister PRNG implemented through the av_random* functions
1723 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1726 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1727 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1728 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1729 and av_fifo_realloc2.
1730 In addition, the order of the function arguments of av_fifo_generic_read
1731 was changed to match av_fifo_generic_write.
1732 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1733 applications, they may not use sizeof() or directly access members.
1735 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1736 Introduce a new metadata API (see av_metadata_get() and friends).
1737 The old API is now deprecated and should not be used anymore. This especially
1738 includes the following structure fields:
1739 - AVFormatContext.title
1740 - AVFormatContext.author
1741 - AVFormatContext.copyright
1742 - AVFormatContext.comment
1743 - AVFormatContext.album
1744 - AVFormatContext.year
1745 - AVFormatContext.track
1746 - AVFormatContext.genre
1749 - AVProgram.provider_name
