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

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

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

767 e1d9dbf Add a new installed header - buffersrc.h
768 It contains a new function av_buffersrc_buffer() that allows passing
769 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()

1678 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1679 Introduce the av_fifo_space() function.
1681 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1682 Move AVPacket declaration from libavformat/avformat.h to
1683 libavcodec/avcodec.h.
1685 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1686 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1687 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1688 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1689 PIX_FMT_BGR32_1 are now macros.
1690 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1691 Re-sort the enum PixelFormat list accordingly.
1692 This change breaks API/ABI backward compatibility.
1694 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1695 Add the enum PixelFormat values:
1696 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1697 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1699 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1700 The Mersenne Twister PRNG implemented through the av_random* functions
1701 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1704 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1705 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1706 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1707 and av_fifo_realloc2.
1708 In addition, the order of the function arguments of av_fifo_generic_read
1709 was changed to match av_fifo_generic_write.
1710 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1711 applications, they may not use sizeof() or directly access members.
1713 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1714 Introduce a new metadata API (see av_metadata_get() and friends).
1715 The old API is now deprecated and should not be used anymore. This especially
1716 includes the following structure fields:
1717 - AVFormatContext.title
1718 - AVFormatContext.author
1719 - AVFormatContext.copyright
1720 - AVFormatContext.comment
1721 - AVFormatContext.album
1722 - AVFormatContext.year
1723 - AVFormatContext.track
1724 - AVFormatContext.genre
1727 - AVProgram.provider_name
