1521 Remove the next field from AVFilter, this is not anymore required.
1523 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1524 Introduce the avfilter_next() function.
1526 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1527 Change the signature of avfilter_register() to make it return an
1528 int. This is required since now the registration operation may fail.
1530 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1531 Make the pixdesc.h API public.
1533 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

1550 Add w and h fields to AVFilterPic.
1552 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1553 This is now an unsigned int instead of a signed int.
1555 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1556 Add a pts field to AVSubtitle which gives the subtitle packet pts
1557 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1558 not work right without this.
1560 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1561 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1562 major version. Use AV_PKT_FLAG_KEY instead.
1564 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1565 av_lockmgr_register() can be used to register a callback function
1566 that lavc (and in the future, libraries that depend on lavc) can use
1567 to implement mutexes. The application should provide a callback function
1568 that implements the AV_LOCK_* operations described in avcodec.h.
1569 When the lock manager is registered, FFmpeg is guaranteed to behave
1570 correctly in a multi-threaded application.
1572 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1573 av_free_packet() is no longer an inline function. It is now exported.
1575 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1576 Please use NULL instead. This has been supported since r16506
1577 (lavf > 52.23.1, lavc > 52.10.0).
1579 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1580 The old decoding functions are deprecated, all new code should use the
1581 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1582 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1583 argument instead of a const uint8_t *buf / int buf_size pair.
1585 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1586 Introduce the av_fifo_space() function.
1588 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1589 Move AVPacket declaration from libavformat/avformat.h to
1590 libavcodec/avcodec.h.
1592 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1593 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1594 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1595 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1596 PIX_FMT_BGR32_1 are now macros.
1597 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1598 Re-sort the enum PixelFormat list accordingly.
1599 This change breaks API/ABI backward compatibility.
1601 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1602 Add the enum PixelFormat values:
1603 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1604 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1606 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1607 The Mersenne Twister PRNG implemented through the av_random* functions
1608 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1611 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1612 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1613 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1614 and av_fifo_realloc2.
1615 In addition, the order of the function arguments of av_fifo_generic_read
1616 was changed to match av_fifo_generic_write.
1617 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1618 applications, they may not use sizeof() or directly access members.
1620 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1621 Introduce a new metadata API (see av_metadata_get() and friends).
1622 The old API is now deprecated and should not be used anymore. This especially
1623 includes the following structure fields:
1624 - AVFormatContext.title
1625 - AVFormatContext.author
1626 - AVFormatContext.copyright
1627 - AVFormatContext.comment
1628 - AVFormatContext.album
1629 - AVFormatContext.year
1630 - AVFormatContext.track
1631 - AVFormatContext.genre
1634 - AVProgram.provider_name
