1556 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1557 Introduce the avfilter_next() function.
1559 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1560 Change the signature of avfilter_register() to make it return an
1561 int. This is required since now the registration operation may fail.
1563 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1564 Make the pixdesc.h API public.

1588 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1589 Add a pts field to AVSubtitle which gives the subtitle packet pts
1590 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1591 not work right without this.
1593 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1594 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1595 major version. Use AV_PKT_FLAG_KEY instead.
1597 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1598 av_lockmgr_register() can be used to register a callback function
1599 that lavc (and in the future, libraries that depend on lavc) can use
1600 to implement mutexes. The application should provide a callback function
1601 that implements the AV_LOCK_* operations described in avcodec.h.
1602 When the lock manager is registered, FFmpeg is guaranteed to behave
1603 correctly in a multi-threaded application.
1605 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1606 av_free_packet() is no longer an inline function. It is now exported.
1608 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1609 Please use NULL instead. This has been supported since r16506
1610 (lavf > 52.23.1, lavc > 52.10.0).
1612 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1613 The old decoding functions are deprecated, all new code should use the
1614 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1615 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1616 argument instead of a const uint8_t *buf / int buf_size pair.
1618 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1619 Introduce the av_fifo_space() function.
1621 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1622 Move AVPacket declaration from libavformat/avformat.h to
1623 libavcodec/avcodec.h.
1625 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1626 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1627 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1628 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1629 PIX_FMT_BGR32_1 are now macros.
1630 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1631 Re-sort the enum PixelFormat list accordingly.
1632 This change breaks API/ABI backward compatibility.
1634 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1635 Add the enum PixelFormat values:
1636 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1637 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1639 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1640 The Mersenne Twister PRNG implemented through the av_random* functions
1641 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1644 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1645 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1646 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1647 and av_fifo_realloc2.
1648 In addition, the order of the function arguments of av_fifo_generic_read
1649 was changed to match av_fifo_generic_write.
1650 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1651 applications, they may not use sizeof() or directly access members.
1653 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1654 Introduce a new metadata API (see av_metadata_get() and friends).
1655 The old API is now deprecated and should not be used anymore. This especially
1656 includes the following structure fields:
1657 - AVFormatContext.title
1658 - AVFormatContext.author
1659 - AVFormatContext.copyright
1660 - AVFormatContext.comment
1661 - AVFormatContext.album
1662 - AVFormatContext.year
1663 - AVFormatContext.track
1664 - AVFormatContext.genre
1667 - AVProgram.provider_name
