1 Never assume the API of libav* to be stable unless at least 1 month has passed
2 since the last major version increase.
4 The last version increases were:
6 libavdevice: 2013-03-xx

36 is now setting AVStream.time_base, instead of AVStream.codec.time_base as was
37 done previously. The old method is now deprecated.
39 2014-04-xx - xxxxxxx - lavc 55.54.0 - avcodec.h
40 Add AVCodecContext.side_data_only_packets to allow encoders to output packets

430 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
431 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
432 Note that this can break user code that includes avcodec.h and uses the
433 'CodecID' identifier. Such code should either #undef CodecID or stop using the

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

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

638 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
639 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().

641 audio decoders to use get_buffer().
643 2011-12-04 - 560f773 - lavc 53.24.0
644 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1465 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1466 Change the signature of avfilter_register() to make it return an
1467 int. This is required since now the registration operation may fail.
1469 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1470 Make the pixdesc.h API public.

1494 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1495 Add a pts field to AVSubtitle which gives the subtitle packet pts
1496 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

1499 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1500 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1501 major version. Use AV_PKT_FLAG_KEY instead.
1503 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1504 av_lockmgr_register() can be used to register a callback function
1505 that lavc (and in the future, libraries that depend on lavc) can use
1506 to implement mutexes. The application should provide a callback function
1507 that implements the AV_LOCK_* operations described in avcodec.h.
1508 When the lock manager is registered, FFmpeg is guaranteed to behave
1509 correctly in a multi-threaded application.
1511 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1512 av_free_packet() is no longer an inline function. It is now exported.
1514 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1515 Please use NULL instead. This has been supported since r16506
1516 (lavf > 52.23.1, lavc > 52.10.0).
1518 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1519 The old decoding functions are deprecated, all new code should use the
1520 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1521 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1522 argument instead of a const uint8_t *buf / int buf_size pair.
1524 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1525 Introduce the av_fifo_space() function.
1527 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1528 Move AVPacket declaration from libavformat/avformat.h to
1529 libavcodec/avcodec.h.
1531 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1532 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1533 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1534 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1535 PIX_FMT_BGR32_1 are now macros.
1536 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1537 Re-sort the enum PixelFormat list accordingly.
1538 This change breaks API/ABI backward compatibility.
1540 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1541 Add the enum PixelFormat values:
1542 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1543 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1545 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1546 The Mersenne Twister PRNG implemented through the av_random* functions
1547 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1550 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1551 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1552 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1553 and av_fifo_realloc2.
1554 In addition, the order of the function arguments of av_fifo_generic_read
1555 was changed to match av_fifo_generic_write.
1556 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1557 applications, they may not use sizeof() or directly access members.
1559 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1560 Introduce a new metadata API (see av_metadata_get() and friends).
1561 The old API is now deprecated and should not be used anymore. This especially
1562 includes the following structure fields:
1563 - AVFormatContext.title
1564 - AVFormatContext.author
1565 - AVFormatContext.copyright
1566 - AVFormatContext.comment
1567 - AVFormatContext.album
1568 - AVFormatContext.year
1569 - AVFormatContext.track
1570 - AVFormatContext.genre
1573 - AVProgram.provider_name
