1 Never assume the API of libav* to be stable unless at least 1 month has passed
2 since the last major version increase or the API was added.
4 The last version increases were:
6 libavdevice: 2015-08-28
7 libavfilter: 2015-08-28
8 libavformat: 2015-08-28
9 libavresample: 2015-08-28
10 libpostproc: 2015-08-28
11 libswresample: 2015-08-28
12 libswscale: 2015-08-28

1208 Add avfilter_pad_get_type() and avfilter_pad_get_name(). Those
1209 should now be used instead of accessing AVFilterPad members

1234 For audio formats with fixed frame size, the last frame
1235 no longer needs to be padded with silence, libavcodec
1236 will handle this internally (effectively all encoders
1237 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2352 (AVFilterFormats **) rather than an (AVFilterFormats *) as before.
2354 2010-01-03 - 4fd1f18 - lavfi 1.13.0 - avfilter_add_colorspace()
2355 Add avfilter_add_colorspace().
2357 2010-01-02 - 8eb631f - lavf 52.46.0 - av_match_ext()
2358 Add av_match_ext(), it should be used in place of match_ext().

2379 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
2380 Remove the next field from AVFilter, this is not anymore required.
2382 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2383 Introduce the avfilter_next() function.
2385 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2386 Change the signature of avfilter_register() to make it return an
2387 int. This is required since now the registration operation may fail.
2389 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2390 Make the pixdesc.h API public.
2392 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2411 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2412 This is now an unsigned int instead of a signed int.
2414 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2415 Add a pts field to AVSubtitle which gives the subtitle packet pts
2416 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2417 not work right without this.
2419 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2420 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2421 major version. Use AV_PKT_FLAG_KEY instead.
2423 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2424 av_lockmgr_register() can be used to register a callback function
2425 that lavc (and in the future, libraries that depend on lavc) can use
2426 to implement mutexes. The application should provide a callback function
2427 that implements the AV_LOCK_* operations described in avcodec.h.
2428 When the lock manager is registered, FFmpeg is guaranteed to behave
2429 correctly in a multi-threaded application.
2431 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2432 av_free_packet() is no longer an inline function. It is now exported.
2434 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2435 Please use NULL instead. This has been supported since r16506
2436 (lavf > 52.23.1, lavc > 52.10.0).
2438 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2439 The old decoding functions are deprecated, all new code should use the
2440 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2441 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2442 argument instead of a const uint8_t *buf / int buf_size pair.
2444 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2445 Introduce the av_fifo_space() function.
2447 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2448 Move AVPacket declaration from libavformat/avformat.h to
2449 libavcodec/avcodec.h.
2451 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2452 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2453 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2454 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2455 PIX_FMT_BGR32_1 are now macros.
2456 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2457 Re-sort the enum PixelFormat list accordingly.
2458 This change breaks API/ABI backward compatibility.
2460 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2461 Add the enum PixelFormat values:
2462 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2463 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2465 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2466 The Mersenne Twister PRNG implemented through the av_random* functions
2467 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2470 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2471 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2472 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2473 and av_fifo_realloc2.
2474 In addition, the order of the function arguments of av_fifo_generic_read
2475 was changed to match av_fifo_generic_write.
2476 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2477 applications, they may not use sizeof() or directly access members.
2479 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2480 Introduce a new metadata API (see av_metadata_get() and friends).
2481 The old API is now deprecated and should not be used anymore. This especially
2482 includes the following structure fields:
2483 - AVFormatContext.title
2484 - AVFormatContext.author
2485 - AVFormatContext.copyright
2486 - AVFormatContext.comment
2487 - AVFormatContext.album
2488 - AVFormatContext.year
2489 - AVFormatContext.track
2490 - AVFormatContext.genre
2493 - AVProgram.provider_name
