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

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

740 e1d9dbf Add a new installed header - buffersrc.h
741 It contains a new function av_buffersrc_buffer() that allows passing
742 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
743 it allows for direct rendering.
744 1c9e340 Add avfilter_copy_frame_props() for copying properties from

765 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
766 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
767 avcodec_decode_audio4() writes output samples to an AVFrame, which allows
768 audio decoders to use get_buffer().

1593 Change the signature of avfilter_register() to make it return an
1594 int. This is required since now the registration operation may fail.
1596 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1597 Make the pixdesc.h API public.

1621 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1622 Add a pts field to AVSubtitle which gives the subtitle packet pts
1623 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1624 not work right without this.
1626 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1627 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1628 major version. Use AV_PKT_FLAG_KEY instead.
1630 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1631 av_lockmgr_register() can be used to register a callback function
1632 that lavc (and in the future, libraries that depend on lavc) can use
1633 to implement mutexes. The application should provide a callback function
1634 that implements the AV_LOCK_* operations described in avcodec.h.
1635 When the lock manager is registered, FFmpeg is guaranteed to behave
1636 correctly in a multi-threaded application.
1638 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1639 av_free_packet() is no longer an inline function. It is now exported.
1641 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1642 Please use NULL instead. This has been supported since r16506
1643 (lavf > 52.23.1, lavc > 52.10.0).
1645 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1646 The old decoding functions are deprecated, all new code should use the
1647 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1648 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1649 argument instead of a const uint8_t *buf / int buf_size pair.
1651 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1652 Introduce the av_fifo_space() function.

1655 Move AVPacket declaration from libavformat/avformat.h to
1656 libavcodec/avcodec.h.
1658 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1659 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1660 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1661 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1662 PIX_FMT_BGR32_1 are now macros.
1663 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1664 Re-sort the enum PixelFormat list accordingly.
1665 This change breaks API/ABI backward compatibility.
1667 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1668 Add the enum PixelFormat values:
1669 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1670 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1672 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1673 The Mersenne Twister PRNG implemented through the av_random* functions
1674 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions

1678 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1679 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1680 and av_fifo_realloc2.
1681 In addition, the order of the function arguments of av_fifo_generic_read
1682 was changed to match av_fifo_generic_write.
