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

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

1683 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1684 argument instead of a const uint8_t *buf / int buf_size pair.
1686 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1687 Introduce the av_fifo_space() function.
1689 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1690 Move AVPacket declaration from libavformat/avformat.h to
1691 libavcodec/avcodec.h.
1693 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1694 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1695 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1696 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1697 PIX_FMT_BGR32_1 are now macros.
1698 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1699 Re-sort the enum PixelFormat list accordingly.
1700 This change breaks API/ABI backward compatibility.
1702 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1703 Add the enum PixelFormat values:
1704 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1705 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1707 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1708 The Mersenne Twister PRNG implemented through the av_random* functions
1709 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1712 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1713 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1714 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1715 and av_fifo_realloc2.
1716 In addition, the order of the function arguments of av_fifo_generic_read
1717 was changed to match av_fifo_generic_write.
1718 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1719 applications, they may not use sizeof() or directly access members.
1721 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1722 Introduce a new metadata API (see av_metadata_get() and friends).
1723 The old API is now deprecated and should not be used anymore. This especially
1724 includes the following structure fields:
1725 - AVFormatContext.title
1726 - AVFormatContext.author
1727 - AVFormatContext.copyright
1728 - AVFormatContext.comment
1729 - AVFormatContext.album
1730 - AVFormatContext.year
1731 - AVFormatContext.track
1732 - AVFormatContext.genre
1735 - AVProgram.provider_name
