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

514 'PixelFormat' identifier. Such code should either #undef PixelFormat
515 or stop using the PixelFormat name.

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

1590 Change the signature of avfilter_register() to make it return an
1591 int. This is required since now the registration operation may fail.
1593 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1594 Make the pixdesc.h API public.

1618 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1619 Add a pts field to AVSubtitle which gives the subtitle packet pts
1620 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1621 not work right without this.
1623 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1624 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1625 major version. Use AV_PKT_FLAG_KEY instead.
1627 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1628 av_lockmgr_register() can be used to register a callback function
1629 that lavc (and in the future, libraries that depend on lavc) can use
1630 to implement mutexes. The application should provide a callback function
1631 that implements the AV_LOCK_* operations described in avcodec.h.
1632 When the lock manager is registered, FFmpeg is guaranteed to behave
1633 correctly in a multi-threaded application.
1635 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1636 av_free_packet() is no longer an inline function. It is now exported.
1638 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1639 Please use NULL instead. This has been supported since r16506
1640 (lavf > 52.23.1, lavc > 52.10.0).
1642 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1643 The old decoding functions are deprecated, all new code should use the
1644 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1645 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1646 argument instead of a const uint8_t *buf / int buf_size pair.
1648 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1649 Introduce the av_fifo_space() function.

1652 Move AVPacket declaration from libavformat/avformat.h to
1653 libavcodec/avcodec.h.
1655 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1656 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1657 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1658 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1659 PIX_FMT_BGR32_1 are now macros.
1660 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1661 Re-sort the enum PixelFormat list accordingly.
1662 This change breaks API/ABI backward compatibility.
1664 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1665 Add the enum PixelFormat values:
1666 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1667 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1669 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1670 The Mersenne Twister PRNG implemented through the av_random* functions
1671 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions

1675 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1676 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write

1678 In addition, the order of the function arguments of av_fifo_generic_read
1679 was changed to match av_fifo_generic_write.
