457 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
458 To provide backwards compatibility, CodecID is now #defined as AVCodecID.

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

640 e1d9dbf Add a new installed header - buffersrc.h
641 It contains a new function av_buffersrc_buffer() that allows passing
642 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()

668 audio decoders to use get_buffer().
670 2011-12-04 - 560f773 - lavc 53.24.0
671 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1489 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1490 Introduce the avfilter_next() function.
1492 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1493 Change the signature of avfilter_register() to make it return an
1494 int. This is required since now the registration operation may fail.
1496 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1497 Make the pixdesc.h API public.
1499 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

1516 Add w and h fields to AVFilterPic.
1518 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1519 This is now an unsigned int instead of a signed int.
1521 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1522 Add a pts field to AVSubtitle which gives the subtitle packet pts
1523 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1524 not work right without this.
1526 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1527 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1528 major version. Use AV_PKT_FLAG_KEY instead.
1530 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1531 av_lockmgr_register() can be used to register a callback function
1532 that lavc (and in the future, libraries that depend on lavc) can use
1533 to implement mutexes. The application should provide a callback function
1534 that implements the AV_LOCK_* operations described in avcodec.h.
1535 When the lock manager is registered, FFmpeg is guaranteed to behave
1536 correctly in a multi-threaded application.
1538 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1539 av_free_packet() is no longer an inline function. It is now exported.
1541 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1542 Please use NULL instead. This has been supported since r16506
1543 (lavf > 52.23.1, lavc > 52.10.0).
1545 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1546 The old decoding functions are deprecated, all new code should use the
1547 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1548 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1549 argument instead of a const uint8_t *buf / int buf_size pair.
1551 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1552 Introduce the av_fifo_space() function.
1554 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1555 Move AVPacket declaration from libavformat/avformat.h to
1556 libavcodec/avcodec.h.
1558 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1559 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1560 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1561 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1562 PIX_FMT_BGR32_1 are now macros.
1563 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1564 Re-sort the enum PixelFormat list accordingly.
1565 This change breaks API/ABI backward compatibility.
1567 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1568 Add the enum PixelFormat values:
1569 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1570 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1572 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1573 The Mersenne Twister PRNG implemented through the av_random* functions
1574 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1577 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1578 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1579 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1580 and av_fifo_realloc2.
1581 In addition, the order of the function arguments of av_fifo_generic_read
1582 was changed to match av_fifo_generic_write.
1583 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1584 applications, they may not use sizeof() or directly access members.
1586 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1587 Introduce a new metadata API (see av_metadata_get() and friends).
1588 The old API is now deprecated and should not be used anymore. This especially
1589 includes the following structure fields:
1590 - AVFormatContext.title
1591 - AVFormatContext.author
1592 - AVFormatContext.copyright
1593 - AVFormatContext.comment
1594 - AVFormatContext.album
1595 - AVFormatContext.year
1596 - AVFormatContext.track
1597 - AVFormatContext.genre
1600 - AVProgram.provider_name
