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

536 'PixelFormat' identifier. Such code should either #undef PixelFormat
537 or stop using the PixelFormat name.

640 For audio formats with fixed frame size, the last frame
641 no longer needs to be padded with silence, libavcodec
642 will handle this internally (effectively all encoders
643 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).
645 2012-05-07 - 828bd08 - lavc 54.13.0 - avcodec.h

759 e1d9dbf Add a new installed header - buffersrc.h
760 It contains a new function av_buffersrc_buffer() that allows passing
761 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
762 it allows for direct rendering.
763 1c9e340 Add avfilter_copy_frame_props() for copying properties from

787 audio decoders to use get_buffer().
789 2011-12-04 - 560f773 - lavc 53.24.0
790 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1679 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1680 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1681 PIX_FMT_BGR32_1 are now macros.
1682 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1683 Re-sort the enum PixelFormat list accordingly.
1684 This change breaks API/ABI backward compatibility.
1686 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1687 Add the enum PixelFormat values:
1688 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1689 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1691 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1692 The Mersenne Twister PRNG implemented through the av_random* functions
1693 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1696 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1697 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1698 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1699 and av_fifo_realloc2.
1700 In addition, the order of the function arguments of av_fifo_generic_read
1701 was changed to match av_fifo_generic_write.
1702 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1703 applications, they may not use sizeof() or directly access members.
1705 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1706 Introduce a new metadata API (see av_metadata_get() and friends).
1707 The old API is now deprecated and should not be used anymore. This especially
1708 includes the following structure fields:
1709 - AVFormatContext.title
1710 - AVFormatContext.author
1711 - AVFormatContext.copyright
1712 - AVFormatContext.comment
1713 - AVFormatContext.album
1714 - AVFormatContext.year
1715 - AVFormatContext.track
1716 - AVFormatContext.genre
1719 - AVProgram.provider_name
