426 data. Add new API for working with reference-counted AVFrames.
427 759001c - add the refcounted_frames field to AVCodecContext to make audio and

436 been called from outside of lavc.
437 Deprecate the following AVFrame fields:
438 * base -- is now stored in AVBufferRef
439 * reference, type, buffer_hints -- are unnecessary in the new API
440 * hwaccel_picture_private, owner, thread_opaque -- should not
441 have been acessed from outside of lavc
442 * qscale_table, qstride, qscale_type, mbskip_table, motion_val,
443 mb_type, dct_coeff, ref_index -- mpegvideo-specific tables,
444 which are not exported anymore.

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

511 'PixelFormat' identifier. Such code should either #undef PixelFormat
512 or stop using the PixelFormat name.

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

734 e1d9dbf Add a new installed header - buffersrc.h
735 It contains a new function av_buffersrc_buffer() that allows passing
736 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
737 it allows for direct rendering.
738 1c9e340 Add avfilter_copy_frame_props() for copying properties from
739 AVFrame to AVFilterBufferRef.

759 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
760 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().

1587 Change the signature of avfilter_register() to make it return an
1588 int. This is required since now the registration operation may fail.
1590 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1591 Make the pixdesc.h API public.

1615 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1616 Add a pts field to AVSubtitle which gives the subtitle packet pts
1617 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1618 not work right without this.
1620 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1621 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1622 major version. Use AV_PKT_FLAG_KEY instead.
1624 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1625 av_lockmgr_register() can be used to register a callback function
1626 that lavc (and in the future, libraries that depend on lavc) can use
1627 to implement mutexes. The application should provide a callback function
1628 that implements the AV_LOCK_* operations described in avcodec.h.
1629 When the lock manager is registered, FFmpeg is guaranteed to behave
1630 correctly in a multi-threaded application.
1632 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1633 av_free_packet() is no longer an inline function. It is now exported.
1635 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1636 Please use NULL instead. This has been supported since r16506
1637 (lavf > 52.23.1, lavc > 52.10.0).
1639 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1640 The old decoding functions are deprecated, all new code should use the
1641 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1642 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1643 argument instead of a const uint8_t *buf / int buf_size pair.
1645 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1646 Introduce the av_fifo_space() function.

1649 Move AVPacket declaration from libavformat/avformat.h to
1650 libavcodec/avcodec.h.
1652 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1653 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1654 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1655 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1656 PIX_FMT_BGR32_1 are now macros.
1657 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1658 Re-sort the enum PixelFormat list accordingly.
1659 This change breaks API/ABI backward compatibility.
1661 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1662 Add the enum PixelFormat values:
1663 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1664 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1666 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1667 The Mersenne Twister PRNG implemented through the av_random* functions
1668 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1671 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1672 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1673 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1674 and av_fifo_realloc2.
