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

527 'PixelFormat' identifier. Such code should either #undef PixelFormat
528 or stop using the PixelFormat name.

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

1600 Introduce the avfilter_next() function.
1602 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1603 Change the signature of avfilter_register() to make it return an
1604 int. This is required since now the registration operation may fail.
1606 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1607 Make the pixdesc.h API public.

1631 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1632 Add a pts field to AVSubtitle which gives the subtitle packet pts
1633 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1634 not work right without this.
1636 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1637 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1638 major version. Use AV_PKT_FLAG_KEY instead.
1640 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1641 av_lockmgr_register() can be used to register a callback function
1642 that lavc (and in the future, libraries that depend on lavc) can use
1643 to implement mutexes. The application should provide a callback function
1644 that implements the AV_LOCK_* operations described in avcodec.h.
1645 When the lock manager is registered, FFmpeg is guaranteed to behave
1646 correctly in a multi-threaded application.
1648 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1649 av_free_packet() is no longer an inline function. It is now exported.
1651 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1652 Please use NULL instead. This has been supported since r16506
1653 (lavf > 52.23.1, lavc > 52.10.0).
1655 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1656 The old decoding functions are deprecated, all new code should use the
1657 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1658 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1659 argument instead of a const uint8_t *buf / int buf_size pair.
1661 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1662 Introduce the av_fifo_space() function.

1665 Move AVPacket declaration from libavformat/avformat.h to
1666 libavcodec/avcodec.h.
1668 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1669 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1670 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1671 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1672 PIX_FMT_BGR32_1 are now macros.
1673 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1674 Re-sort the enum PixelFormat list accordingly.
1675 This change breaks API/ABI backward compatibility.
1677 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1678 Add the enum PixelFormat values:
1679 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1680 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1682 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1683 The Mersenne Twister PRNG implemented through the av_random* functions
1684 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1687 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1688 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1689 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1690 and av_fifo_realloc2.
1691 In addition, the order of the function arguments of av_fifo_generic_read
1692 was changed to match av_fifo_generic_write.
1693 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1694 applications, they may not use sizeof() or directly access members.
1696 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
