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

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

1683 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1684 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1685 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1686 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1687 PIX_FMT_BGR32_1 are now macros.
1688 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1689 Re-sort the enum PixelFormat list accordingly.
1690 This change breaks API/ABI backward compatibility.
1692 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1693 Add the enum PixelFormat values:
1694 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1695 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1697 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1698 The Mersenne Twister PRNG implemented through the av_random* functions
1699 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1702 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1703 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1704 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1705 and av_fifo_realloc2.
1706 In addition, the order of the function arguments of av_fifo_generic_read
1707 was changed to match av_fifo_generic_write.
1708 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1709 applications, they may not use sizeof() or directly access members.
1711 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1712 Introduce a new metadata API (see av_metadata_get() and friends).
1713 The old API is now deprecated and should not be used anymore. This especially
1714 includes the following structure fields:
1715 - AVFormatContext.title
1716 - AVFormatContext.author
1717 - AVFormatContext.copyright
1718 - AVFormatContext.comment
1719 - AVFormatContext.album
1720 - AVFormatContext.year
1721 - AVFormatContext.track
1722 - AVFormatContext.genre
1725 - AVProgram.provider_name
