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

520 'PixelFormat' identifier. Such code should either #undef PixelFormat
521 or stop using the PixelFormat name.

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

1596 Change the signature of avfilter_register() to make it return an
1597 int. This is required since now the registration operation may fail.
1599 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1600 Make the pixdesc.h API public.

1624 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1625 Add a pts field to AVSubtitle which gives the subtitle packet pts
1626 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1627 not work right without this.
1629 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1630 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1631 major version. Use AV_PKT_FLAG_KEY instead.
1633 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1634 av_lockmgr_register() can be used to register a callback function
1635 that lavc (and in the future, libraries that depend on lavc) can use
1636 to implement mutexes. The application should provide a callback function
1637 that implements the AV_LOCK_* operations described in avcodec.h.
1638 When the lock manager is registered, FFmpeg is guaranteed to behave
1639 correctly in a multi-threaded application.
1641 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1642 av_free_packet() is no longer an inline function. It is now exported.
1644 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1645 Please use NULL instead. This has been supported since r16506
1646 (lavf > 52.23.1, lavc > 52.10.0).
1648 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1649 The old decoding functions are deprecated, all new code should use the
1650 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1651 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1652 argument instead of a const uint8_t *buf / int buf_size pair.
1654 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1655 Introduce the av_fifo_space() function.

1658 Move AVPacket declaration from libavformat/avformat.h to
1659 libavcodec/avcodec.h.
1661 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1662 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1663 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1664 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1665 PIX_FMT_BGR32_1 are now macros.
1666 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1667 Re-sort the enum PixelFormat list accordingly.
1668 This change breaks API/ABI backward compatibility.
1670 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1671 Add the enum PixelFormat values:
1672 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1673 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

1681 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1682 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1683 and av_fifo_realloc2.
1684 In addition, the order of the function arguments of av_fifo_generic_read
1685 was changed to match av_fifo_generic_write.
