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
7 libavfilter: 2013-12-xx
8 libavformat: 2013-03-xx
9 libavresample: 2012-10-05
10 libswscale: 2011-06-20
14 API changes, most recent first:
16 2014-06-xx - xxxxxxx - lavc 55.55.0 - avcodec.h
17 Add av_packet_rescale_ts() to simplify timestamp conversion.
19 2014-xx-xx - xxxxxxx - lavf 55.20.0 - avformat.h
20 The proper way for providing a hint about the desired timebase to the muxers
21 is now setting AVStream.time_base, instead of AVStream.codec.time_base as was
22 done previously. The old method is now deprecated.
24 2014-04-xx - xxxxxxx - lavc 55.54.0 - avcodec.h
25 Add AVCodecContext.side_data_only_packets to allow encoders to output packets
26 with only side data. This option may become mandatory in the future, so all

1443 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1444 Change the signature of avfilter_register() to make it return an
1445 int. This is required since now the registration operation may fail.
1447 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1448 Make the pixdesc.h API public.

1472 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1473 Add a pts field to AVSubtitle which gives the subtitle packet pts
1474 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

1477 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1478 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1479 major version. Use AV_PKT_FLAG_KEY instead.
1481 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1482 av_lockmgr_register() can be used to register a callback function
1483 that lavc (and in the future, libraries that depend on lavc) can use
1484 to implement mutexes. The application should provide a callback function
1485 that implements the AV_LOCK_* operations described in avcodec.h.
1486 When the lock manager is registered, FFmpeg is guaranteed to behave
1487 correctly in a multi-threaded application.
1489 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1490 av_free_packet() is no longer an inline function. It is now exported.
1492 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1493 Please use NULL instead. This has been supported since r16506
1494 (lavf > 52.23.1, lavc > 52.10.0).
1496 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1497 The old decoding functions are deprecated, all new code should use the
1498 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1499 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1500 argument instead of a const uint8_t *buf / int buf_size pair.
1502 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1503 Introduce the av_fifo_space() function.
1505 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1506 Move AVPacket declaration from libavformat/avformat.h to
1507 libavcodec/avcodec.h.
1509 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1510 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1511 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1512 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1513 PIX_FMT_BGR32_1 are now macros.
1514 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1515 Re-sort the enum PixelFormat list accordingly.
1516 This change breaks API/ABI backward compatibility.
1518 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1519 Add the enum PixelFormat values:
1520 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1521 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1523 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1524 The Mersenne Twister PRNG implemented through the av_random* functions
1525 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1528 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1529 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1530 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1531 and av_fifo_realloc2.
1532 In addition, the order of the function arguments of av_fifo_generic_read
1533 was changed to match av_fifo_generic_write.
1534 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1535 applications, they may not use sizeof() or directly access members.
1537 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1538 Introduce a new metadata API (see av_metadata_get() and friends).
1539 The old API is now deprecated and should not be used anymore. This especially
1540 includes the following structure fields:
1541 - AVFormatContext.title
1542 - AVFormatContext.author
1543 - AVFormatContext.copyright
1544 - AVFormatContext.comment
1545 - AVFormatContext.album
1546 - AVFormatContext.year
1547 - AVFormatContext.track
1548 - AVFormatContext.genre
1551 - AVProgram.provider_name
