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

530 'PixelFormat' identifier. Such code should either #undef PixelFormat
531 or stop using the PixelFormat name.

634 For audio formats with fixed frame size, the last frame
635 no longer needs to be padded with silence, libavcodec
636 will handle this internally (effectively all encoders

1605 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1606 Change the signature of avfilter_register() to make it return an
1607 int. This is required since now the registration operation may fail.
1609 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1610 Make the pixdesc.h API public.
1612 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

1634 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1635 Add a pts field to AVSubtitle which gives the subtitle packet pts
1636 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1637 not work right without this.
1639 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1640 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1641 major version. Use AV_PKT_FLAG_KEY instead.
1643 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1644 av_lockmgr_register() can be used to register a callback function
1645 that lavc (and in the future, libraries that depend on lavc) can use
1646 to implement mutexes. The application should provide a callback function
1647 that implements the AV_LOCK_* operations described in avcodec.h.
1648 When the lock manager is registered, FFmpeg is guaranteed to behave
1649 correctly in a multi-threaded application.
1651 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1652 av_free_packet() is no longer an inline function. It is now exported.
1654 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1655 Please use NULL instead. This has been supported since r16506
1656 (lavf > 52.23.1, lavc > 52.10.0).
1658 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1659 The old decoding functions are deprecated, all new code should use the
1660 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1661 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1662 argument instead of a const uint8_t *buf / int buf_size pair.
1664 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1665 Introduce the av_fifo_space() function.

1668 Move AVPacket declaration from libavformat/avformat.h to
1669 libavcodec/avcodec.h.
1671 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1672 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1673 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1674 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1675 PIX_FMT_BGR32_1 are now macros.
1676 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1677 Re-sort the enum PixelFormat list accordingly.
1678 This change breaks API/ABI backward compatibility.
1680 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1681 Add the enum PixelFormat values:
1682 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1683 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1685 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1686 The Mersenne Twister PRNG implemented through the av_random* functions
1687 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1690 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1691 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1692 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1693 and av_fifo_realloc2.
1694 In addition, the order of the function arguments of av_fifo_generic_read
1695 was changed to match av_fifo_generic_write.
1696 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1697 applications, they may not use sizeof() or directly access members.
1699 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1700 Introduce a new metadata API (see av_metadata_get() and friends).
1701 The old API is now deprecated and should not be used anymore. This especially
1702 includes the following structure fields:
1703 - AVFormatContext.title
1704 - AVFormatContext.author
1705 - AVFormatContext.copyright
1706 - AVFormatContext.comment
1707 - AVFormatContext.album
1708 - AVFormatContext.year
1709 - AVFormatContext.track
1710 - AVFormatContext.genre
1713 - AVProgram.provider_name
