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 2014-07-xx - xxxxxxx - lavu 53.18.0 - display.h
17 Add av_display_matrix_flip() to flip the transformation matrix.

1459 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1460 Change the signature of avfilter_register() to make it return an
1461 int. This is required since now the registration operation may fail.
1463 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1464 Make the pixdesc.h API public.

1488 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1489 Add a pts field to AVSubtitle which gives the subtitle packet pts
1490 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

1493 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1494 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1495 major version. Use AV_PKT_FLAG_KEY instead.
1497 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1498 av_lockmgr_register() can be used to register a callback function
1499 that lavc (and in the future, libraries that depend on lavc) can use
1500 to implement mutexes. The application should provide a callback function
1501 that implements the AV_LOCK_* operations described in avcodec.h.
1502 When the lock manager is registered, FFmpeg is guaranteed to behave
1503 correctly in a multi-threaded application.
1505 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1506 av_free_packet() is no longer an inline function. It is now exported.
1508 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1509 Please use NULL instead. This has been supported since r16506
1510 (lavf > 52.23.1, lavc > 52.10.0).
1512 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1513 The old decoding functions are deprecated, all new code should use the
1514 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1515 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1516 argument instead of a const uint8_t *buf / int buf_size pair.
1518 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1519 Introduce the av_fifo_space() function.
1521 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1522 Move AVPacket declaration from libavformat/avformat.h to
1523 libavcodec/avcodec.h.
1525 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1526 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1527 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1528 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1529 PIX_FMT_BGR32_1 are now macros.
1530 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1531 Re-sort the enum PixelFormat list accordingly.
1532 This change breaks API/ABI backward compatibility.
1534 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1535 Add the enum PixelFormat values:
1536 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1537 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1539 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1540 The Mersenne Twister PRNG implemented through the av_random* functions
1541 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1544 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1545 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1546 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1547 and av_fifo_realloc2.
1548 In addition, the order of the function arguments of av_fifo_generic_read
1549 was changed to match av_fifo_generic_write.
1550 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1551 applications, they may not use sizeof() or directly access members.
1553 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1554 Introduce a new metadata API (see av_metadata_get() and friends).
1555 The old API is now deprecated and should not be used anymore. This especially
1556 includes the following structure fields:
1557 - AVFormatContext.title
1558 - AVFormatContext.author
1559 - AVFormatContext.copyright
1560 - AVFormatContext.comment
1561 - AVFormatContext.album
1562 - AVFormatContext.year
1563 - AVFormatContext.track
1564 - AVFormatContext.genre
1567 - AVProgram.provider_name
