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 be used for freeing an AVFrame.
1137 2012-09-12 - e3e09f2 / 8919fee - lavu 51.73.100 / 51.41.0 - audioconvert.h
1138 Added AV_CH_LOW_FREQUENCY_2 channel mask value.

1161 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
1162 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
1163 Note that this can break user code that includes avcodec.h and uses the
1164 'CodecID' identifier. Such code should either #undef CodecID or stop using the

1192 Add avfilter_pad_get_type() and avfilter_pad_get_name(). Those
1193 should now be used instead of accessing AVFilterPad members
1196 2012-06-12 - 3630a07 / b0f0dfc - lavu 51.57.100 / 51.32.0 - audioconvert.h
1197 Add av_get_channel_layout_channel_index(), av_get_channel_name()
1198 and av_channel_layout_extract_channel().

1217 2012-05-09 - 61930bd / a5117a2 - lavc 54.21.101 / 54.13.1
1218 For audio formats with fixed frame size, the last frame
1219 no longer needs to be padded with silence, libavcodec
1220 will handle this internally (effectively all encoders
1221 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2364 Remove the next field from AVFilter, this is not anymore required.
2366 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2367 Introduce the avfilter_next() function.
2369 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2370 Change the signature of avfilter_register() to make it return an
2371 int. This is required since now the registration operation may fail.
2373 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2374 Make the pixdesc.h API public.
2376 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2398 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2399 Add a pts field to AVSubtitle which gives the subtitle packet pts
2400 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2401 not work right without this.
2403 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2404 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2405 major version. Use AV_PKT_FLAG_KEY instead.
2407 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2408 av_lockmgr_register() can be used to register a callback function
2409 that lavc (and in the future, libraries that depend on lavc) can use
2410 to implement mutexes. The application should provide a callback function
2411 that implements the AV_LOCK_* operations described in avcodec.h.
2412 When the lock manager is registered, FFmpeg is guaranteed to behave
2413 correctly in a multi-threaded application.
2415 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2416 av_free_packet() is no longer an inline function. It is now exported.
2418 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2419 Please use NULL instead. This has been supported since r16506
2420 (lavf > 52.23.1, lavc > 52.10.0).
2422 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2423 The old decoding functions are deprecated, all new code should use the
2424 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2425 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2426 argument instead of a const uint8_t *buf / int buf_size pair.
2428 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2429 Introduce the av_fifo_space() function.
2431 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2432 Move AVPacket declaration from libavformat/avformat.h to
2433 libavcodec/avcodec.h.
2435 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2436 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2437 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2438 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2439 PIX_FMT_BGR32_1 are now macros.
2440 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2441 Re-sort the enum PixelFormat list accordingly.
2442 This change breaks API/ABI backward compatibility.
2444 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2445 Add the enum PixelFormat values:
2446 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2447 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2449 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2450 The Mersenne Twister PRNG implemented through the av_random* functions
2451 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2454 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2455 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2456 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2457 and av_fifo_realloc2.
2458 In addition, the order of the function arguments of av_fifo_generic_read
2459 was changed to match av_fifo_generic_write.
2460 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2461 applications, they may not use sizeof() or directly access members.
2463 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2464 Introduce a new metadata API (see av_metadata_get() and friends).
2465 The old API is now deprecated and should not be used anymore. This especially
2466 includes the following structure fields:
2467 - AVFormatContext.title
2468 - AVFormatContext.author
2469 - AVFormatContext.copyright
2470 - AVFormatContext.comment
2471 - AVFormatContext.album
2472 - AVFormatContext.year
2473 - AVFormatContext.track
2474 - AVFormatContext.genre
2477 - AVProgram.provider_name
