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

1136 Data planes parameters to avresample_convert() and
1137 avresample_read() are now uint8_t** instead of void**.
1138 Libavresample is now stable.

1144 Add avcodec_free_frame(). This function must now
1145 be used for freeing an AVFrame.
1147 2012-09-12 - e3e09f2 / 8919fee - lavu 51.73.100 / 51.41.0 - audioconvert.h
1148 Added AV_CH_LOW_FREQUENCY_2 channel mask value.
1150 2012-09-04 - b21b5b0 / 686a329 - lavu 51.71.100 / 51.40.0 - opt.h

1171 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
1172 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
1173 Note that this can break user code that includes avcodec.h and uses the
1174 'CodecID' identifier. Such code should either #undef CodecID or stop using the

1202 Add avfilter_pad_get_type() and avfilter_pad_get_name(). Those
1203 should now be used instead of accessing AVFilterPad members
1206 2012-06-12 - 3630a07 / b0f0dfc - lavu 51.57.100 / 51.32.0 - audioconvert.h
1207 Add av_get_channel_layout_channel_index(), av_get_channel_name()
1208 and av_channel_layout_extract_channel().

1227 2012-05-09 - 61930bd / a5117a2 - lavc 54.21.101 / 54.13.1
1228 For audio formats with fixed frame size, the last frame
1229 no longer needs to be padded with silence, libavcodec
1230 will handle this internally (effectively all encoders
1231 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2376 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2377 Introduce the avfilter_next() function.
2379 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2380 Change the signature of avfilter_register() to make it return an
2381 int. This is required since now the registration operation may fail.

2408 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2409 Add a pts field to AVSubtitle which gives the subtitle packet pts
2410 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2411 not work right without this.
2413 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2414 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2415 major version. Use AV_PKT_FLAG_KEY instead.
2417 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2418 av_lockmgr_register() can be used to register a callback function
2419 that lavc (and in the future, libraries that depend on lavc) can use
2420 to implement mutexes. The application should provide a callback function
2421 that implements the AV_LOCK_* operations described in avcodec.h.
2422 When the lock manager is registered, FFmpeg is guaranteed to behave
2423 correctly in a multi-threaded application.
2425 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2426 av_free_packet() is no longer an inline function. It is now exported.
2428 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2429 Please use NULL instead. This has been supported since r16506
2430 (lavf > 52.23.1, lavc > 52.10.0).
2432 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2433 The old decoding functions are deprecated, all new code should use the
2434 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2435 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2436 argument instead of a const uint8_t *buf / int buf_size pair.
2438 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2439 Introduce the av_fifo_space() function.
2441 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2442 Move AVPacket declaration from libavformat/avformat.h to
2443 libavcodec/avcodec.h.
2445 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2446 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2447 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2448 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2449 PIX_FMT_BGR32_1 are now macros.
2450 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2451 Re-sort the enum PixelFormat list accordingly.
2452 This change breaks API/ABI backward compatibility.
2454 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2455 Add the enum PixelFormat values:
2456 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2457 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2459 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2460 The Mersenne Twister PRNG implemented through the av_random* functions
2461 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2464 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2465 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2466 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2467 and av_fifo_realloc2.
2468 In addition, the order of the function arguments of av_fifo_generic_read
2469 was changed to match av_fifo_generic_write.
2470 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2471 applications, they may not use sizeof() or directly access members.
2473 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2474 Introduce a new metadata API (see av_metadata_get() and friends).
2475 The old API is now deprecated and should not be used anymore. This especially
2476 includes the following structure fields:
2477 - AVFormatContext.title
2478 - AVFormatContext.author
2479 - AVFormatContext.copyright
2480 - AVFormatContext.comment
2481 - AVFormatContext.album
2482 - AVFormatContext.year
2483 - AVFormatContext.track
2484 - AVFormatContext.genre
2487 - AVProgram.provider_name
