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

1136 be used for freeing an AVFrame.
1138 2012-09-12 - e3e09f2 / 8919fee - lavu 51.73.100 / 51.41.0 - audioconvert.h
1139 Added AV_CH_LOW_FREQUENCY_2 channel mask value.
1141 2012-09-04 - b21b5b0 / 686a329 - lavu 51.71.100 / 51.40.0 - opt.h

1162 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
1163 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
1164 Note that this can break user code that includes avcodec.h and uses the
1165 'CodecID' identifier. Such code should either #undef CodecID or stop using the

1193 Add avfilter_pad_get_type() and avfilter_pad_get_name(). Those
1194 should now be used instead of accessing AVFilterPad members
1197 2012-06-12 - 3630a07 / b0f0dfc - lavu 51.57.100 / 51.32.0 - audioconvert.h
1198 Add av_get_channel_layout_channel_index(), av_get_channel_name()
1199 and av_channel_layout_extract_channel().

1218 2012-05-09 - 61930bd / a5117a2 - lavc 54.21.101 / 54.13.1
1219 For audio formats with fixed frame size, the last frame
1220 no longer needs to be padded with silence, libavcodec
1221 will handle this internally (effectively all encoders
1222 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2367 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2368 Introduce the avfilter_next() function.
2370 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2371 Change the signature of avfilter_register() to make it return an
2372 int. This is required since now the registration operation may fail.
2374 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2375 Make the pixdesc.h API public.
2377 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2399 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2400 Add a pts field to AVSubtitle which gives the subtitle packet pts
2401 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2402 not work right without this.
2404 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2405 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2406 major version. Use AV_PKT_FLAG_KEY instead.
2408 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2409 av_lockmgr_register() can be used to register a callback function
2410 that lavc (and in the future, libraries that depend on lavc) can use
2411 to implement mutexes. The application should provide a callback function
2412 that implements the AV_LOCK_* operations described in avcodec.h.
2413 When the lock manager is registered, FFmpeg is guaranteed to behave
2414 correctly in a multi-threaded application.
2416 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2417 av_free_packet() is no longer an inline function. It is now exported.
2419 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2420 Please use NULL instead. This has been supported since r16506
2421 (lavf > 52.23.1, lavc > 52.10.0).
2423 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2424 The old decoding functions are deprecated, all new code should use the
2425 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2426 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2427 argument instead of a const uint8_t *buf / int buf_size pair.
2429 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2430 Introduce the av_fifo_space() function.
2432 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2433 Move AVPacket declaration from libavformat/avformat.h to
2434 libavcodec/avcodec.h.
2436 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2437 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2438 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2439 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2440 PIX_FMT_BGR32_1 are now macros.
2441 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2442 Re-sort the enum PixelFormat list accordingly.
2443 This change breaks API/ABI backward compatibility.
2445 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2446 Add the enum PixelFormat values:
2447 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2448 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2450 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2451 The Mersenne Twister PRNG implemented through the av_random* functions
2452 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2455 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2456 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2457 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2458 and av_fifo_realloc2.
2459 In addition, the order of the function arguments of av_fifo_generic_read
2460 was changed to match av_fifo_generic_write.
2461 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2462 applications, they may not use sizeof() or directly access members.
2464 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2465 Introduce a new metadata API (see av_metadata_get() and friends).
2466 The old API is now deprecated and should not be used anymore. This especially
2467 includes the following structure fields:
2468 - AVFormatContext.title
2469 - AVFormatContext.author
2470 - AVFormatContext.copyright
2471 - AVFormatContext.comment
2472 - AVFormatContext.album
2473 - AVFormatContext.year
2474 - AVFormatContext.track
2475 - AVFormatContext.genre
2478 - AVProgram.provider_name
