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

1138 Add avcodec_free_frame(). This function must now
1139 be used for freeing an AVFrame.
1141 2012-09-12 - e3e09f2 / 8919fee - lavu 51.73.100 / 51.41.0 - audioconvert.h
1142 Added AV_CH_LOW_FREQUENCY_2 channel mask value.
1144 2012-09-04 - b21b5b0 / 686a329 - lavu 51.71.100 / 51.40.0 - opt.h

1165 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
1166 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
1167 Note that this can break user code that includes avcodec.h and uses the
1168 'CodecID' identifier. Such code should either #undef CodecID or stop using the

1196 Add avfilter_pad_get_type() and avfilter_pad_get_name(). Those
1197 should now be used instead of accessing AVFilterPad members
1200 2012-06-12 - 3630a07 / b0f0dfc - lavu 51.57.100 / 51.32.0 - audioconvert.h
1201 Add av_get_channel_layout_channel_index(), av_get_channel_name()
1202 and av_channel_layout_extract_channel().

1221 2012-05-09 - 61930bd / a5117a2 - lavc 54.21.101 / 54.13.1
1222 For audio formats with fixed frame size, the last frame
1223 no longer needs to be padded with silence, libavcodec
1224 will handle this internally (effectively all encoders
1225 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2368 Remove the next field from AVFilter, this is not anymore required.
2370 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2371 Introduce the avfilter_next() function.
2373 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2374 Change the signature of avfilter_register() to make it return an
2375 int. This is required since now the registration operation may fail.
2377 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2378 Make the pixdesc.h API public.
2380 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2402 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2403 Add a pts field to AVSubtitle which gives the subtitle packet pts
2404 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

2407 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2408 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2409 major version. Use AV_PKT_FLAG_KEY instead.
2411 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2412 av_lockmgr_register() can be used to register a callback function
2413 that lavc (and in the future, libraries that depend on lavc) can use
2414 to implement mutexes. The application should provide a callback function
2415 that implements the AV_LOCK_* operations described in avcodec.h.
2416 When the lock manager is registered, FFmpeg is guaranteed to behave
2417 correctly in a multi-threaded application.
2419 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2420 av_free_packet() is no longer an inline function. It is now exported.
2422 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2423 Please use NULL instead. This has been supported since r16506
2424 (lavf > 52.23.1, lavc > 52.10.0).
2426 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2427 The old decoding functions are deprecated, all new code should use the
2428 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2429 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2430 argument instead of a const uint8_t *buf / int buf_size pair.
2432 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2433 Introduce the av_fifo_space() function.
2435 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2436 Move AVPacket declaration from libavformat/avformat.h to
2437 libavcodec/avcodec.h.
2439 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2440 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2441 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2442 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2443 PIX_FMT_BGR32_1 are now macros.
2444 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2445 Re-sort the enum PixelFormat list accordingly.
2446 This change breaks API/ABI backward compatibility.
2448 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2449 Add the enum PixelFormat values:
2450 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2451 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2453 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2454 The Mersenne Twister PRNG implemented through the av_random* functions
2455 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2458 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2459 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2460 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2461 and av_fifo_realloc2.
2462 In addition, the order of the function arguments of av_fifo_generic_read
2463 was changed to match av_fifo_generic_write.
2464 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2465 applications, they may not use sizeof() or directly access members.
2467 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2468 Introduce a new metadata API (see av_metadata_get() and friends).
2469 The old API is now deprecated and should not be used anymore. This especially
2470 includes the following structure fields:
2471 - AVFormatContext.title
2472 - AVFormatContext.author
2473 - AVFormatContext.copyright
2474 - AVFormatContext.comment
2475 - AVFormatContext.album
2476 - AVFormatContext.year
2477 - AVFormatContext.track
2478 - AVFormatContext.genre
2481 - AVProgram.provider_name
