416 AVFrame.buf/extended_buf to allow reference counting for the AVFrame
417 data. Add new API for working with reference-counted AVFrames.
418 759001c - add the refcounted_frames field to AVCodecContext to make audio and
419 video decoders return reference-counted frames. Add get_buffer2()
420 callback to AVCodecContext which allocates reference-counted frames.
421 Add avcodec_default_get_buffer2() as the default get_buffer2()
423 Deprecate AVCodecContext.get_buffer() / release_buffer() /
424 reget_buffer(), avcodec_default_get_buffer(),

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

1577 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1578 Change the signature of avfilter_register() to make it return an
1579 int. This is required since now the registration operation may fail.
1581 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1582 Make the pixdesc.h API public.

1603 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1604 This is now an unsigned int instead of a signed int.
1606 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1607 Add a pts field to AVSubtitle which gives the subtitle packet pts
1608 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1609 not work right without this.
1611 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1612 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1613 major version. Use AV_PKT_FLAG_KEY instead.
1615 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1616 av_lockmgr_register() can be used to register a callback function
1617 that lavc (and in the future, libraries that depend on lavc) can use
1618 to implement mutexes. The application should provide a callback function
1619 that implements the AV_LOCK_* operations described in avcodec.h.
1620 When the lock manager is registered, FFmpeg is guaranteed to behave
1621 correctly in a multi-threaded application.
1623 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1624 av_free_packet() is no longer an inline function. It is now exported.
1626 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1627 Please use NULL instead. This has been supported since r16506
1628 (lavf > 52.23.1, lavc > 52.10.0).
1630 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1631 The old decoding functions are deprecated, all new code should use the
1632 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1633 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1634 argument instead of a const uint8_t *buf / int buf_size pair.
1636 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1637 Introduce the av_fifo_space() function.
1639 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1640 Move AVPacket declaration from libavformat/avformat.h to
1641 libavcodec/avcodec.h.
1643 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1644 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1645 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1646 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1647 PIX_FMT_BGR32_1 are now macros.
1648 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1649 Re-sort the enum PixelFormat list accordingly.
1650 This change breaks API/ABI backward compatibility.
1652 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1653 Add the enum PixelFormat values:
1654 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1655 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1657 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1658 The Mersenne Twister PRNG implemented through the av_random* functions
1659 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1662 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1663 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1664 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1665 and av_fifo_realloc2.
1666 In addition, the order of the function arguments of av_fifo_generic_read
1667 was changed to match av_fifo_generic_write.
1668 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1669 applications, they may not use sizeof() or directly access members.
1671 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1672 Introduce a new metadata API (see av_metadata_get() and friends).
