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

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

1684 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1685 The old decoding functions are deprecated, all new code should use the
1686 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1687 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1688 argument instead of a const uint8_t *buf / int buf_size pair.
1690 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1691 Introduce the av_fifo_space() function.
1693 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1694 Move AVPacket declaration from libavformat/avformat.h to
1695 libavcodec/avcodec.h.
1697 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1698 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1699 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1700 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1701 PIX_FMT_BGR32_1 are now macros.
1702 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1703 Re-sort the enum PixelFormat list accordingly.
1704 This change breaks API/ABI backward compatibility.
1706 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1707 Add the enum PixelFormat values:
1708 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1709 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1711 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1712 The Mersenne Twister PRNG implemented through the av_random* functions
1713 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1716 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1717 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1718 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1719 and av_fifo_realloc2.
1720 In addition, the order of the function arguments of av_fifo_generic_read
1721 was changed to match av_fifo_generic_write.
1722 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1723 applications, they may not use sizeof() or directly access members.
1725 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1726 Introduce a new metadata API (see av_metadata_get() and friends).
1727 The old API is now deprecated and should not be used anymore. This especially
1728 includes the following structure fields:
1729 - AVFormatContext.title
1730 - AVFormatContext.author
1731 - AVFormatContext.copyright
1732 - AVFormatContext.comment
1733 - AVFormatContext.album
1734 - AVFormatContext.year
1735 - AVFormatContext.track
1736 - AVFormatContext.genre
1739 - AVProgram.provider_name
