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

1148 be used for freeing an AVFrame.

1205 Add avfilter_pad_get_type() and avfilter_pad_get_name(). Those
1206 should now be used instead of accessing AVFilterPad members
1209 2012-06-12 - 3630a07 / b0f0dfc - lavu 51.57.100 / 51.32.0 - audioconvert.h
1210 Add av_get_channel_layout_channel_index(), av_get_channel_name()
1211 and av_channel_layout_extract_channel().

1231 For audio formats with fixed frame size, the last frame
1232 no longer needs to be padded with silence, libavcodec
1233 will handle this internally (effectively all encoders
1234 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2349 (AVFilterFormats **) rather than an (AVFilterFormats *) as before.
2351 2010-01-03 - 4fd1f18 - lavfi 1.13.0 - avfilter_add_colorspace()
2352 Add avfilter_add_colorspace().
2354 2010-01-02 - 8eb631f - lavf 52.46.0 - av_match_ext()
2355 Add av_match_ext(), it should be used in place of match_ext().
2357 2010-01-01 - a1f547b - lavf 52.45.0 - av_guess_format()
2358 Add av_guess_format(), it should be used in place of guess_format().

2376 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
2377 Remove the next field from AVFilter, this is not anymore required.
2379 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2380 Introduce the avfilter_next() function.
2382 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2383 Change the signature of avfilter_register() to make it return an
2384 int. This is required since now the registration operation may fail.
2386 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2387 Make the pixdesc.h API public.
2389 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2394 Add a description field to AVFilter.
2396 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
2397 Change the interface of avfilter_make_format_list() from

2408 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size

2411 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2412 Add a pts field to AVSubtitle which gives the subtitle packet pts
2413 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2414 not work right without this.
2416 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2417 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2418 major version. Use AV_PKT_FLAG_KEY instead.
2420 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2421 av_lockmgr_register() can be used to register a callback function
2422 that lavc (and in the future, libraries that depend on lavc) can use
2423 to implement mutexes. The application should provide a callback function
2424 that implements the AV_LOCK_* operations described in avcodec.h.
2425 When the lock manager is registered, FFmpeg is guaranteed to behave
2426 correctly in a multi-threaded application.
2428 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2429 av_free_packet() is no longer an inline function. It is now exported.
2431 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2432 Please use NULL instead. This has been supported since r16506
2433 (lavf > 52.23.1, lavc > 52.10.0).
2435 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2436 The old decoding functions are deprecated, all new code should use the
2437 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2438 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2439 argument instead of a const uint8_t *buf / int buf_size pair.
2441 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2442 Introduce the av_fifo_space() function.
2444 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2445 Move AVPacket declaration from libavformat/avformat.h to
2446 libavcodec/avcodec.h.
2448 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2449 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2450 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2451 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2452 PIX_FMT_BGR32_1 are now macros.
2453 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2454 Re-sort the enum PixelFormat list accordingly.
2455 This change breaks API/ABI backward compatibility.
2457 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2458 Add the enum PixelFormat values:
2459 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2460 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2462 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2463 The Mersenne Twister PRNG implemented through the av_random* functions
2464 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2467 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2468 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2469 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2470 and av_fifo_realloc2.
2471 In addition, the order of the function arguments of av_fifo_generic_read
2472 was changed to match av_fifo_generic_write.
2473 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2474 applications, they may not use sizeof() or directly access members.
2476 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2477 Introduce a new metadata API (see av_metadata_get() and friends).
2478 The old API is now deprecated and should not be used anymore. This especially
2479 includes the following structure fields:
2480 - AVFormatContext.title
2481 - AVFormatContext.author
2482 - AVFormatContext.copyright
2483 - AVFormatContext.comment
2484 - AVFormatContext.album
2485 - AVFormatContext.year
2486 - AVFormatContext.track
2487 - AVFormatContext.genre
2490 - AVProgram.provider_name
