540 To provide backwards compatibility, PixelFormat is now #defined as

543 'PixelFormat' identifier. Such code should either #undef PixelFormat
544 or stop using the PixelFormat name.

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

1681 Move AVPacket declaration from libavformat/avformat.h to
1682 libavcodec/avcodec.h.
1684 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1685 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1686 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1687 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1688 PIX_FMT_BGR32_1 are now macros.
1689 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1690 Re-sort the enum PixelFormat list accordingly.
1691 This change breaks API/ABI backward compatibility.
1693 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1694 Add the enum PixelFormat values:
1695 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1696 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1698 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1699 The Mersenne Twister PRNG implemented through the av_random* functions
1700 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1703 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1704 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1705 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1706 and av_fifo_realloc2.
1707 In addition, the order of the function arguments of av_fifo_generic_read
1708 was changed to match av_fifo_generic_write.
1709 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1710 applications, they may not use sizeof() or directly access members.
1712 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1713 Introduce a new metadata API (see av_metadata_get() and friends).
1714 The old API is now deprecated and should not be used anymore. This especially
1715 includes the following structure fields:
1716 - AVFormatContext.title
1717 - AVFormatContext.author
1718 - AVFormatContext.copyright
1719 - AVFormatContext.comment
1720 - AVFormatContext.album
1721 - AVFormatContext.year
1722 - AVFormatContext.track
1723 - AVFormatContext.genre
1726 - AVProgram.provider_name
