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

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

1684 Please use NULL instead. This has been supported since r16506
1685 (lavf > 52.23.1, lavc > 52.10.0).
1687 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1688 The old decoding functions are deprecated, all new code should use the
1689 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1690 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1691 argument instead of a const uint8_t *buf / int buf_size pair.
1693 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1694 Introduce the av_fifo_space() function.
1696 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1697 Move AVPacket declaration from libavformat/avformat.h to
1698 libavcodec/avcodec.h.
1700 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1701 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1702 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1703 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1704 PIX_FMT_BGR32_1 are now macros.
1705 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1706 Re-sort the enum PixelFormat list accordingly.
1707 This change breaks API/ABI backward compatibility.
1709 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1710 Add the enum PixelFormat values:
1711 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1712 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1714 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1715 The Mersenne Twister PRNG implemented through the av_random* functions
1716 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1719 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1720 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1721 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1722 and av_fifo_realloc2.
1723 In addition, the order of the function arguments of av_fifo_generic_read
1724 was changed to match av_fifo_generic_write.
1725 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1726 applications, they may not use sizeof() or directly access members.
1728 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1729 Introduce a new metadata API (see av_metadata_get() and friends).
1730 The old API is now deprecated and should not be used anymore. This especially
1731 includes the following structure fields:
1732 - AVFormatContext.title
1733 - AVFormatContext.author
1734 - AVFormatContext.copyright
1735 - AVFormatContext.comment
1736 - AVFormatContext.album
1737 - AVFormatContext.year
1738 - AVFormatContext.track
1739 - AVFormatContext.genre
1742 - AVProgram.provider_name
