525 For audio formats with fixed frame size, the last frame
526 no longer needs to be padded with silence, libavcodec

647 it allows for direct rendering.
648 1c9e340 Add avfilter_copy_frame_props() for copying properties from
649 AVFrame to AVFilterBufferRef.

669 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
670 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
671 avcodec_decode_audio4() writes output samples to an AVFrame, which allows
672 audio decoders to use get_buffer().
673
674 2011-12-04 - 560f773 - lavc 53.24.0
675 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1530 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1531 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1532 major version. Use AV_PKT_FLAG_KEY instead.
1533
1534 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1535 av_lockmgr_register() can be used to register a callback function
1536 that lavc (and in the future, libraries that depend on lavc) can use
1537 to implement mutexes. The application should provide a callback function
1538 that implements the AV_LOCK_* operations described in avcodec.h.
1539 When the lock manager is registered, FFmpeg is guaranteed to behave
1540 correctly in a multi-threaded application.
1541
1542 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1543 av_free_packet() is no longer an inline function. It is now exported.
1544
1545 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1546 Please use NULL instead. This has been supported since r16506
1547 (lavf > 52.23.1, lavc > 52.10.0).
1548
1549 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1550 The old decoding functions are deprecated, all new code should use the
1551 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1552 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1553 argument instead of a const uint8_t *buf / int buf_size pair.
1554
1555 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1556 Introduce the av_fifo_space() function.
1557
1558 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1559 Move AVPacket declaration from libavformat/avformat.h to
1560 libavcodec/avcodec.h.
1561
1562 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1563 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1564 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1565 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1566 PIX_FMT_BGR32_1 are now macros.
1567 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1568 Re-sort the enum PixelFormat list accordingly.
1569 This change breaks API/ABI backward compatibility.
1570
1571 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1572 Add the enum PixelFormat values:
1573 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1574 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1575
1576 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1577 The Mersenne Twister PRNG implemented through the av_random* functions
1578 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1579 instead.
1580
1581 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1582 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1583 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1584 and av_fifo_realloc2.
1585 In addition, the order of the function arguments of av_fifo_generic_read
1586 was changed to match av_fifo_generic_write.
1587 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1588 applications, they may not use sizeof() or directly access members.
1589
1590 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1591 Introduce a new metadata API (see av_metadata_get() and friends).
1592 The old API is now deprecated and should not be used anymore. This especially
1593 includes the following structure fields:
1594 - AVFormatContext.title
1595 - AVFormatContext.author
1596 - AVFormatContext.copyright
1597 - AVFormatContext.comment
1598 - AVFormatContext.album
1599 - AVFormatContext.year
1600 - AVFormatContext.track
1601 - AVFormatContext.genre
1602 - AVStream.language
1603 - AVStream.filename
1604 - AVProgram.provider_name
1605 - AVProgram.name
1606 - AVChapter.title
