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

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

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

818 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
819 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
820 avcodec_decode_audio4() writes output samples to an AVFrame, which allows
821 audio decoders to use get_buffer().

1677 not work right without this.
1679 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1680 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1681 major version. Use AV_PKT_FLAG_KEY instead.
1683 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1684 av_lockmgr_register() can be used to register a callback function
1685 that lavc (and in the future, libraries that depend on lavc) can use
1686 to implement mutexes. The application should provide a callback function
1687 that implements the AV_LOCK_* operations described in avcodec.h.
1688 When the lock manager is registered, FFmpeg is guaranteed to behave
1689 correctly in a multi-threaded application.
1691 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1692 av_free_packet() is no longer an inline function. It is now exported.
1694 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1695 Please use NULL instead. This has been supported since r16506
1696 (lavf > 52.23.1, lavc > 52.10.0).
1698 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1699 The old decoding functions are deprecated, all new code should use the
1700 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1701 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1702 argument instead of a const uint8_t *buf / int buf_size pair.
1704 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1705 Introduce the av_fifo_space() function.
1707 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1708 Move AVPacket declaration from libavformat/avformat.h to
1709 libavcodec/avcodec.h.
1711 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1712 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1713 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1714 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1715 PIX_FMT_BGR32_1 are now macros.
1716 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1717 Re-sort the enum PixelFormat list accordingly.
1718 This change breaks API/ABI backward compatibility.
1720 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1721 Add the enum PixelFormat values:
1722 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1723 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1725 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1726 The Mersenne Twister PRNG implemented through the av_random* functions
1727 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1730 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1731 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1732 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1733 and av_fifo_realloc2.
1734 In addition, the order of the function arguments of av_fifo_generic_read
1735 was changed to match av_fifo_generic_write.
1736 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1737 applications, they may not use sizeof() or directly access members.
1739 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1740 Introduce a new metadata API (see av_metadata_get() and friends).
1741 The old API is now deprecated and should not be used anymore. This especially
1742 includes the following structure fields:
1743 - AVFormatContext.title
1744 - AVFormatContext.author
1745 - AVFormatContext.copyright
1746 - AVFormatContext.comment
1747 - AVFormatContext.album
1748 - AVFormatContext.year
1749 - AVFormatContext.track
1750 - AVFormatContext.genre
1753 - AVProgram.provider_name
