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

11 libswresample: 2015-08-28
12 libswscale: 2015-08-28

18 2016-xx-xx - xxxxxxx - lavc 57.61.100 / lavc 57.24.0 - avcodec.h
19 Decoders now export the frame timestamp as AVFrame.pts. It was
20 previously exported as AVFrame.pkt_pts, which is now deprecated.
22 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
23 and not the codec timebase.

30 AVCodecContext.hw_frames_ctx now may be used by decoders.

46 Add AVFilterContext.nb_threads.
48 2016-08-15 - c3c4c72 - lavc 57.53.100 - avcodec.h
49 Add trailing_padding to AVCodecContext to match the corresponding
50 field in AVCodecParameters.
52 2016-08-15 - b746ed7 - lavc 57.52.100 - avcodec.h
53 Add a new API for chained BSF filters and passthrough (null) BSF --
54 av_bsf_list_alloc(), av_bsf_list_free(), av_bsf_list_append(),
55 av_bsf_list_append2(), av_bsf_list_finalize(), av_bsf_list_parse_str()

59 Add av_get_frame_filename2()
61 2016-07-09 - 775389f / 90f469a - lavc 57.50.100 / 57.20.0 - avcodec.h
62 Add FF_PROFILE_H264_MULTIVIEW_HIGH and FF_PROFILE_H264_STEREO_HIGH.
64 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
65 Moved codecpar field from AVStream to the end of the struct, so that
66 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
68 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h
69 Moved hw_frames_ctx field from AVFrame to the end of the struct, so that
70 the following private fields are in the same location as in FFmpeg 3.0 (lavu 55.17.103).
72 2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
73 Fix accidental ABI breakage in AVFilterContext.
74 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
76 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
77 compatible with lavfi>=6.47.100. Potentially also affects other users of
78 libavfilter if they are using one of the affected fields.

131 Add requirement to bitstream filtering API that returned packets with
132 size == 0 and side_data_elems == 0 are to be skipped by the caller.
134 2016-03-04 - 9362973 - lavf 57.28.100
135 Add protocol blacklisting API
137 2016-02-28 - 4dd4d53 - lavc 57.27.101
138 Validate AVFrame returned by get_buffer2 to have required

140 and buffer overflow are possible with certain streams if
141 that is not the case.
143 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
144 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
145 the reset of the ASS ReadOrder field on flush. This affects the content of
146 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
149 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
150 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
151 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
152 The default value for this option will change to "ass" at the next major
153 libavcodec version bump.
155 The current default is "ass_with_timings" for compatibility. This means that
156 all subtitles text decoders currently still output ASS with timings printed
157 as strings in the AVSubtitles.rects[N]->ass fields.
159 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
160 timing is limited to a 1/100 time base, so this is relevant for any subtitles
161 format needing a bigger one), ease timing adjustments, and prevents the need
162 of removing the timing from the decoded string yourself. This form is also
163 known as "the Matroska form". The timing information (start time, duration)
164 can be found in the AVSubtitles fields.

2598 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2599 Add a pts field to AVSubtitle which gives the subtitle packet pts
2600 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2601 not work right without this.
2603 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2604 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2605 major version. Use AV_PKT_FLAG_KEY instead.
2607 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2608 av_lockmgr_register() can be used to register a callback function
2609 that lavc (and in the future, libraries that depend on lavc) can use
2610 to implement mutexes. The application should provide a callback function
2611 that implements the AV_LOCK_* operations described in avcodec.h.
2612 When the lock manager is registered, FFmpeg is guaranteed to behave
2613 correctly in a multi-threaded application.
2615 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2616 av_free_packet() is no longer an inline function. It is now exported.
2618 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2619 Please use NULL instead. This has been supported since r16506
2620 (lavf > 52.23.1, lavc > 52.10.0).
2622 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2623 The old decoding functions are deprecated, all new code should use the
2624 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2625 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2626 argument instead of a const uint8_t *buf / int buf_size pair.
2628 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2629 Introduce the av_fifo_space() function.

2632 Move AVPacket declaration from libavformat/avformat.h to
2633 libavcodec/avcodec.h.
2635 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2636 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2637 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2638 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2639 PIX_FMT_BGR32_1 are now macros.
2640 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2641 Re-sort the enum PixelFormat list accordingly.
2642 This change breaks API/ABI backward compatibility.
2644 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2645 Add the enum PixelFormat values:
2646 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2647 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2649 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2650 The Mersenne Twister PRNG implemented through the av_random* functions
2651 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2654 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2655 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2656 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2657 and av_fifo_realloc2.
2658 In addition, the order of the function arguments of av_fifo_generic_read
