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

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

1681 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1682 argument instead of a const uint8_t *buf / int buf_size pair.
1684 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1685 Introduce the av_fifo_space() function.
1687 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1688 Move AVPacket declaration from libavformat/avformat.h to
1689 libavcodec/avcodec.h.
1691 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1692 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1693 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1694 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1695 PIX_FMT_BGR32_1 are now macros.
1696 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1697 Re-sort the enum PixelFormat list accordingly.
1698 This change breaks API/ABI backward compatibility.
1700 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1701 Add the enum PixelFormat values:
1702 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1703 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1705 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1706 The Mersenne Twister PRNG implemented through the av_random* functions
1707 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1710 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1711 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1712 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1713 and av_fifo_realloc2.
1714 In addition, the order of the function arguments of av_fifo_generic_read
1715 was changed to match av_fifo_generic_write.
1716 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1717 applications, they may not use sizeof() or directly access members.
1719 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1720 Introduce a new metadata API (see av_metadata_get() and friends).
1721 The old API is now deprecated and should not be used anymore. This especially
1722 includes the following structure fields:
1723 - AVFormatContext.title
1724 - AVFormatContext.author
1725 - AVFormatContext.copyright
1726 - AVFormatContext.comment
1727 - AVFormatContext.album
1728 - AVFormatContext.year
1729 - AVFormatContext.track
1730 - AVFormatContext.genre
1733 - AVProgram.provider_name
