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

1135 Added AV_CH_LOW_FREQUENCY_2 channel mask value.

1158 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
1159 To provide backwards compatibility, CodecID is now #defined as AVCodecID.

1189 Add avfilter_pad_get_type() and avfilter_pad_get_name(). Those
1190 should now be used instead of accessing AVFilterPad members
1193 2012-06-12 - 3630a07 / b0f0dfc - lavu 51.57.100 / 51.32.0 - audioconvert.h
1194 Add av_get_channel_layout_channel_index(), av_get_channel_name()
1195 and av_channel_layout_extract_channel().

1214 2012-05-09 - 61930bd / a5117a2 - lavc 54.21.101 / 54.13.1
1215 For audio formats with fixed frame size, the last frame
1216 no longer needs to be padded with silence, libavcodec
1217 will handle this internally (effectively all encoders
1218 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2332 Change the avfilter_add_colorspace() signature, make it accept an
2333 (AVFilterFormats **) rather than an (AVFilterFormats *) as before.
2335 2010-01-03 - 4fd1f18 - lavfi 1.13.0 - avfilter_add_colorspace()
2336 Add avfilter_add_colorspace().
2338 2010-01-02 - 8eb631f - lavf 52.46.0 - av_match_ext()

2361 Remove the next field from AVFilter, this is not anymore required.
2363 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2364 Introduce the avfilter_next() function.
2366 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2367 Change the signature of avfilter_register() to make it return an
2368 int. This is required since now the registration operation may fail.
2370 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2371 Make the pixdesc.h API public.
2373 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2378 Add a description field to AVFilter.
2380 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
2381 Change the interface of avfilter_make_format_list() from

2390 Add w and h fields to AVFilterPic.
2392 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size

2395 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2396 Add a pts field to AVSubtitle which gives the subtitle packet pts
2397 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2398 not work right without this.
2400 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2401 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2402 major version. Use AV_PKT_FLAG_KEY instead.
2404 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2405 av_lockmgr_register() can be used to register a callback function
2406 that lavc (and in the future, libraries that depend on lavc) can use
2407 to implement mutexes. The application should provide a callback function
2408 that implements the AV_LOCK_* operations described in avcodec.h.
2409 When the lock manager is registered, FFmpeg is guaranteed to behave
2410 correctly in a multi-threaded application.
2412 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2413 av_free_packet() is no longer an inline function. It is now exported.
2415 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2416 Please use NULL instead. This has been supported since r16506
2417 (lavf > 52.23.1, lavc > 52.10.0).
2419 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2420 The old decoding functions are deprecated, all new code should use the
2421 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2422 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2423 argument instead of a const uint8_t *buf / int buf_size pair.
2425 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2426 Introduce the av_fifo_space() function.
2428 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2429 Move AVPacket declaration from libavformat/avformat.h to
2430 libavcodec/avcodec.h.
2432 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2433 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2434 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2435 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2436 PIX_FMT_BGR32_1 are now macros.
2437 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2438 Re-sort the enum PixelFormat list accordingly.
2439 This change breaks API/ABI backward compatibility.
2441 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2442 Add the enum PixelFormat values:
2443 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2444 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2446 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2447 The Mersenne Twister PRNG implemented through the av_random* functions
2448 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2451 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2452 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2453 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2454 and av_fifo_realloc2.
2455 In addition, the order of the function arguments of av_fifo_generic_read
2456 was changed to match av_fifo_generic_write.
2457 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2458 applications, they may not use sizeof() or directly access members.
2460 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2461 Introduce a new metadata API (see av_metadata_get() and friends).
2462 The old API is now deprecated and should not be used anymore. This especially
2463 includes the following structure fields:
2464 - AVFormatContext.title
2465 - AVFormatContext.author
2466 - AVFormatContext.copyright
2467 - AVFormatContext.comment
2468 - AVFormatContext.album
2469 - AVFormatContext.year
2470 - AVFormatContext.track
2471 - AVFormatContext.genre
2474 - AVProgram.provider_name
