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

1155 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
1156 To provide backwards compatibility, CodecID is now #defined as AVCodecID.

1186 Add avfilter_pad_get_type() and avfilter_pad_get_name(). Those
1187 should now be used instead of accessing AVFilterPad members

1211 2012-05-09 - 61930bd / a5117a2 - lavc 54.21.101 / 54.13.1
1212 For audio formats with fixed frame size, the last frame
1213 no longer needs to be padded with silence, libavcodec
1214 will handle this internally (effectively all encoders
1215 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2330 (AVFilterFormats **) rather than an (AVFilterFormats *) as before.
2332 2010-01-03 - 4fd1f18 - lavfi 1.13.0 - avfilter_add_colorspace()
2333 Add avfilter_add_colorspace().
2335 2010-01-02 - 8eb631f - lavf 52.46.0 - av_match_ext()

2358 Remove the next field from AVFilter, this is not anymore required.
2360 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2361 Introduce the avfilter_next() function.
2363 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2364 Change the signature of avfilter_register() to make it return an
2365 int. This is required since now the registration operation may fail.
2367 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2368 Make the pixdesc.h API public.
2370 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2375 Add a description field to AVFilter.
2377 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
2378 Change the interface of avfilter_make_format_list() from

2387 Add w and h fields to AVFilterPic.
2389 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2390 This is now an unsigned int instead of a signed int.
2392 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2393 Add a pts field to AVSubtitle which gives the subtitle packet pts
2394 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2395 not work right without this.
2397 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2398 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2399 major version. Use AV_PKT_FLAG_KEY instead.
2401 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2402 av_lockmgr_register() can be used to register a callback function
2403 that lavc (and in the future, libraries that depend on lavc) can use
2404 to implement mutexes. The application should provide a callback function
2405 that implements the AV_LOCK_* operations described in avcodec.h.
2406 When the lock manager is registered, FFmpeg is guaranteed to behave
2407 correctly in a multi-threaded application.
2409 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2410 av_free_packet() is no longer an inline function. It is now exported.
2412 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2413 Please use NULL instead. This has been supported since r16506
2414 (lavf > 52.23.1, lavc > 52.10.0).
2416 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2417 The old decoding functions are deprecated, all new code should use the
2418 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2419 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2420 argument instead of a const uint8_t *buf / int buf_size pair.
2422 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2423 Introduce the av_fifo_space() function.
2425 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2426 Move AVPacket declaration from libavformat/avformat.h to
2427 libavcodec/avcodec.h.
2429 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2430 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2431 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2432 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2433 PIX_FMT_BGR32_1 are now macros.
2434 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2435 Re-sort the enum PixelFormat list accordingly.
2436 This change breaks API/ABI backward compatibility.
2438 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2439 Add the enum PixelFormat values:
2440 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2441 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2443 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2444 The Mersenne Twister PRNG implemented through the av_random* functions
2445 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2448 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2449 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2450 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2451 and av_fifo_realloc2.
2452 In addition, the order of the function arguments of av_fifo_generic_read
2453 was changed to match av_fifo_generic_write.
2454 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2455 applications, they may not use sizeof() or directly access members.
2457 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2458 Introduce a new metadata API (see av_metadata_get() and friends).
2459 The old API is now deprecated and should not be used anymore. This especially
2460 includes the following structure fields:
2461 - AVFormatContext.title
2462 - AVFormatContext.author
2463 - AVFormatContext.copyright
2464 - AVFormatContext.comment
2465 - AVFormatContext.album
2466 - AVFormatContext.year
2467 - AVFormatContext.track
2468 - AVFormatContext.genre
2471 - AVProgram.provider_name
