31 previously exported as AVFrame.pkt_pts, which is now deprecated.
33 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
34 and not the codec timebase.

60 Add trailing_padding to AVCodecContext to match the corresponding
61 field in AVCodecParameters.
63 2016-08-15 - b746ed7 - lavc 57.52.100 - avcodec.h
64 Add a new API for chained BSF filters and passthrough (null) BSF --
65 av_bsf_list_alloc(), av_bsf_list_free(), av_bsf_list_append(),
66 av_bsf_list_append2(), av_bsf_list_finalize(), av_bsf_list_parse_str()

70 Add av_get_frame_filename2()
72 2016-07-09 - 775389f / 90f469a - lavc 57.50.100 / 57.20.0 - avcodec.h
73 Add FF_PROFILE_H264_MULTIVIEW_HIGH and FF_PROFILE_H264_STEREO_HIGH.
75 2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
76 Moved codecpar field from AVStream to the end of the struct, so that
77 the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
79 2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h
80 Moved hw_frames_ctx field from AVFrame to the end of the struct, so that
81 the following private fields are in the same location as in FFmpeg 3.0 (lavu 55.17.103).
83 2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
84 Fix accidental ABI breakage in AVFilterContext.
85 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
87 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
88 compatible with lavfi>=6.47.100. Potentially also affects other users of
89 libavfilter if they are using one of the affected fields.
91 -------- 8< --------- FFmpeg 3.1 was cut here -------- 8< ---------
93 2016-06-26 - 481f320 / 1c9e861 - lavu 55.27.100 / 55.13.0 - hwcontext.h

125 2016-04-14 - 28abb21 / 551c677 - lavu 55.22.100 / 55.9.0 - hwcontext_vaapi.h
126 Add new installed header with VAAPI-specific hwcontext definitions.
128 2016-04-14 - afccfaf / b1f01e8 - lavu 55.21.100 / 55.7.0 - hwcontext.h
129 Add AVHWFramesConstraints and associated API.
131 2016-04-11 - 6f69f7a / 9200514 - lavf 57.33.100 / 57.5.0 - avformat.h

142 Add requirement to bitstream filtering API that returned packets with
143 size == 0 and side_data_elems == 0 are to be skipped by the caller.
145 2016-03-04 - 9362973 - lavf 57.28.100
146 Add protocol blacklisting API
148 2016-02-28 - 4dd4d53 - lavc 57.27.101
149 Validate AVFrame returned by get_buffer2 to have required
150 planes not NULL and unused planes set to NULL as crashes
151 and buffer overflow are possible with certain streams if
152 that is not the case.
154 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
155 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
156 the reset of the ASS ReadOrder field on flush. This affects the content of
157 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
160 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
161 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
162 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
163 The default value for this option will change to "ass" at the next major
164 libavcodec version bump.
166 The current default is "ass_with_timings" for compatibility. This means that
167 all subtitles text decoders currently still output ASS with timings printed
168 as strings in the AVSubtitles.rects[N]->ass fields.
170 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
171 timing is limited to a 1/100 time base, so this is relevant for any subtitles
172 format needing a bigger one), ease timing adjustments, and prevents the need
173 of removing the timing from the decoded string yourself. This form is also
174 known as "the Matroska form". The timing information (start time, duration)
175 can be found in the AVSubtitles fields.

2609 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2610 Add a pts field to AVSubtitle which gives the subtitle packet pts
2611 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2612 not work right without this.
2614 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2615 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2616 major version. Use AV_PKT_FLAG_KEY instead.
2618 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2619 av_lockmgr_register() can be used to register a callback function
2620 that lavc (and in the future, libraries that depend on lavc) can use
2621 to implement mutexes. The application should provide a callback function
2622 that implements the AV_LOCK_* operations described in avcodec.h.
2623 When the lock manager is registered, FFmpeg is guaranteed to behave
2624 correctly in a multi-threaded application.
2626 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2627 av_free_packet() is no longer an inline function. It is now exported.
2629 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2630 Please use NULL instead. This has been supported since r16506
2631 (lavf > 52.23.1, lavc > 52.10.0).
2633 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2634 The old decoding functions are deprecated, all new code should use the
2635 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2636 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2637 argument instead of a const uint8_t *buf / int buf_size pair.
2639 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2640 Introduce the av_fifo_space() function.

2643 Move AVPacket declaration from libavformat/avformat.h to
2644 libavcodec/avcodec.h.
2646 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2647 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2648 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2649 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2650 PIX_FMT_BGR32_1 are now macros.
2651 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2652 Re-sort the enum PixelFormat list accordingly.
2653 This change breaks API/ABI backward compatibility.
2655 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2656 Add the enum PixelFormat values:
2657 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2658 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2660 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2661 The Mersenne Twister PRNG implemented through the av_random* functions
2662 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2665 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2666 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2667 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2668 and av_fifo_realloc2.
2669 In addition, the order of the function arguments of av_fifo_generic_read
2670 was changed to match av_fifo_generic_write.
2671 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2672 applications, they may not use sizeof() or directly access members.
