414 data. Add new API for working with reference-counted AVFrames.
415 759001c - add the refcounted_frames field to AVCodecContext to make audio and
416 video decoders return reference-counted frames. Add get_buffer2()
417 callback to AVCodecContext which allocates reference-counted frames.
418 Add avcodec_default_get_buffer2() as the default get_buffer2()

421 reget_buffer(), avcodec_default_get_buffer(),

424 been called from outside of lavc.
425 Deprecate the following AVFrame fields:
426 * base -- is now stored in AVBufferRef
427 * reference, type, buffer_hints -- are unnecessary in the new API
428 * hwaccel_picture_private, owner, thread_opaque -- should not
429 have been acessed from outside of lavc
430 * qscale_table, qstride, qscale_type, mbskip_table, motion_val,
431 mb_type, dct_coeff, ref_index -- mpegvideo-specific tables,
432 which are not exported anymore.

434 av_buffersrc_add_frame(), deprecate av_buffersrc_buffer().

1571 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1572 Introduce the avfilter_next() function.
1574 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1575 Change the signature of avfilter_register() to make it return an
1576 int. This is required since now the registration operation may fail.
1578 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1579 Make the pixdesc.h API public.

1603 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1604 Add a pts field to AVSubtitle which gives the subtitle packet pts
1605 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1606 not work right without this.
1608 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1609 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1610 major version. Use AV_PKT_FLAG_KEY instead.
1612 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1613 av_lockmgr_register() can be used to register a callback function
1614 that lavc (and in the future, libraries that depend on lavc) can use
1615 to implement mutexes. The application should provide a callback function
1616 that implements the AV_LOCK_* operations described in avcodec.h.
1617 When the lock manager is registered, FFmpeg is guaranteed to behave
1618 correctly in a multi-threaded application.
1620 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1621 av_free_packet() is no longer an inline function. It is now exported.
1623 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1624 Please use NULL instead. This has been supported since r16506
1625 (lavf > 52.23.1, lavc > 52.10.0).
1627 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1628 The old decoding functions are deprecated, all new code should use the
1629 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1630 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1631 argument instead of a const uint8_t *buf / int buf_size pair.
1633 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1634 Introduce the av_fifo_space() function.
1636 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1637 Move AVPacket declaration from libavformat/avformat.h to
1638 libavcodec/avcodec.h.
1640 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1641 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1642 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1643 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1644 PIX_FMT_BGR32_1 are now macros.
1645 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1646 Re-sort the enum PixelFormat list accordingly.
1647 This change breaks API/ABI backward compatibility.
1649 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1650 Add the enum PixelFormat values:
1651 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1652 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1654 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1655 The Mersenne Twister PRNG implemented through the av_random* functions
1656 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1659 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1660 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1661 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1662 and av_fifo_realloc2.
1663 In addition, the order of the function arguments of av_fifo_generic_read
1664 was changed to match av_fifo_generic_write.
1665 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1666 applications, they may not use sizeof() or directly access members.
1668 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1669 Introduce a new metadata API (see av_metadata_get() and friends).
1670 The old API is now deprecated and should not be used anymore. This especially
1671 includes the following structure fields:
1672 - AVFormatContext.title
1673 - AVFormatContext.author
1674 - AVFormatContext.copyright
