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

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

1679 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1680 argument instead of a const uint8_t *buf / int buf_size pair.
1682 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1683 Introduce the av_fifo_space() function.
1685 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1686 Move AVPacket declaration from libavformat/avformat.h to
1687 libavcodec/avcodec.h.
1689 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1690 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1691 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1692 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1693 PIX_FMT_BGR32_1 are now macros.
1694 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1695 Re-sort the enum PixelFormat list accordingly.
1696 This change breaks API/ABI backward compatibility.
1698 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1699 Add the enum PixelFormat values:
1700 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1701 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1703 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1704 The Mersenne Twister PRNG implemented through the av_random* functions
1705 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1708 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1709 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1710 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1711 and av_fifo_realloc2.
1712 In addition, the order of the function arguments of av_fifo_generic_read
1713 was changed to match av_fifo_generic_write.
1714 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1715 applications, they may not use sizeof() or directly access members.
1717 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1718 Introduce a new metadata API (see av_metadata_get() and friends).
1719 The old API is now deprecated and should not be used anymore. This especially
1720 includes the following structure fields:
1721 - AVFormatContext.title
1722 - AVFormatContext.author
1723 - AVFormatContext.copyright
1724 - AVFormatContext.comment
1725 - AVFormatContext.album
1726 - AVFormatContext.year
1727 - AVFormatContext.track
1728 - AVFormatContext.genre
1731 - AVProgram.provider_name
