520 To provide backwards compatibility, PixelFormat is now #defined as
522 Note that this can break user code that includes pixfmt.h and uses the
523 'PixelFormat' identifier. Such code should either #undef PixelFormat
524 or stop using the PixelFormat name.

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

746 e1d9dbf Add a new installed header - buffersrc.h
747 It contains a new function av_buffersrc_buffer() that allows passing
748 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
749 it allows for direct rendering.

1599 Change the signature of avfilter_register() to make it return an
1600 int. This is required since now the registration operation may fail.

1627 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1628 Add a pts field to AVSubtitle which gives the subtitle packet pts
1629 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1630 not work right without this.
1632 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1633 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1634 major version. Use AV_PKT_FLAG_KEY instead.
1636 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1637 av_lockmgr_register() can be used to register a callback function
1638 that lavc (and in the future, libraries that depend on lavc) can use
1639 to implement mutexes. The application should provide a callback function
1640 that implements the AV_LOCK_* operations described in avcodec.h.
1641 When the lock manager is registered, FFmpeg is guaranteed to behave
1642 correctly in a multi-threaded application.
1644 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1645 av_free_packet() is no longer an inline function. It is now exported.
1647 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1648 Please use NULL instead. This has been supported since r16506
1649 (lavf > 52.23.1, lavc > 52.10.0).
1651 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1652 The old decoding functions are deprecated, all new code should use the
1653 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1654 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1655 argument instead of a const uint8_t *buf / int buf_size pair.
1657 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1658 Introduce the av_fifo_space() function.

1661 Move AVPacket declaration from libavformat/avformat.h to
1662 libavcodec/avcodec.h.
1664 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1665 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1666 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1667 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1668 PIX_FMT_BGR32_1 are now macros.
1669 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1670 Re-sort the enum PixelFormat list accordingly.
1671 This change breaks API/ABI backward compatibility.
1673 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1674 Add the enum PixelFormat values:

1676 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

1684 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1685 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1686 and av_fifo_realloc2.
1687 In addition, the order of the function arguments of av_fifo_generic_read
1688 was changed to match av_fifo_generic_write.
