1534 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1535 Introduce the avfilter_next() function.
1537 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1538 Change the signature of avfilter_register() to make it return an
1539 int. This is required since now the registration operation may fail.
1541 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1542 Make the pixdesc.h API public.

1561 Add w and h fields to AVFilterPic.
1563 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1564 This is now an unsigned int instead of a signed int.
1566 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1567 Add a pts field to AVSubtitle which gives the subtitle packet pts
1568 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1569 not work right without this.
1571 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1572 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1573 major version. Use AV_PKT_FLAG_KEY instead.
1575 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1576 av_lockmgr_register() can be used to register a callback function
1577 that lavc (and in the future, libraries that depend on lavc) can use
1578 to implement mutexes. The application should provide a callback function
1579 that implements the AV_LOCK_* operations described in avcodec.h.
1580 When the lock manager is registered, FFmpeg is guaranteed to behave
1581 correctly in a multi-threaded application.
1583 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1584 av_free_packet() is no longer an inline function. It is now exported.
1586 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1587 Please use NULL instead. This has been supported since r16506
1588 (lavf > 52.23.1, lavc > 52.10.0).
1590 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1591 The old decoding functions are deprecated, all new code should use the
1592 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1593 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1594 argument instead of a const uint8_t *buf / int buf_size pair.
1596 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1597 Introduce the av_fifo_space() function.
1599 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1600 Move AVPacket declaration from libavformat/avformat.h to
1601 libavcodec/avcodec.h.
1603 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1604 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1605 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1606 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1607 PIX_FMT_BGR32_1 are now macros.
1608 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1609 Re-sort the enum PixelFormat list accordingly.
1610 This change breaks API/ABI backward compatibility.
1612 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1613 Add the enum PixelFormat values:
1614 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1615 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1617 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1618 The Mersenne Twister PRNG implemented through the av_random* functions
1619 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1622 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1623 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1624 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1625 and av_fifo_realloc2.
1626 In addition, the order of the function arguments of av_fifo_generic_read
1627 was changed to match av_fifo_generic_write.
1628 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1629 applications, they may not use sizeof() or directly access members.
1631 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1632 Introduce a new metadata API (see av_metadata_get() and friends).
1633 The old API is now deprecated and should not be used anymore. This especially
1634 includes the following structure fields:
1635 - AVFormatContext.title
1636 - AVFormatContext.author
1637 - AVFormatContext.copyright
1638 - AVFormatContext.comment
1639 - AVFormatContext.album
1640 - AVFormatContext.year
1641 - AVFormatContext.track
1642 - AVFormatContext.genre
1645 - AVProgram.provider_name
