327 Users of this library are asked to migrate to libswresample, which, as well as
328 providing more functionality, is faster and has higher accuracy.

388 Deprecate AVCodecContext.refcounted_frames. This was useful for deprecated

476 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
477 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
478 set the Cuda device handle.
480 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

504 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
505 (via an entry named "rotate"). Use av_stream_get_side_data() with
506 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
507 av_display_rotation_get(). The same is done for muxing. Instead of adding a
508 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
509 to be added to the AVStream.

524 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
525 bump, and libavformat will behave as if it were always set.
526 Deprecate av_packet_merge_side_data() and av_packet_split_side_data().

535 2017-03-18 - 3796fb2692 - lavfi 6.77.100 - avfilter.h
536 Deprecate AVFilterGraph.resample_lavr_opts
537 It's never been used by avfilter nor passed to anything.

544 2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
545 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
546 native decoder format. (The default value is not changed.)
548 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
549 Remove requirement to use AVOption or accessors to access certain fields
550 in AVFrame, AVCodecContext, and AVFormatContext that were previously
551 documented as "no direct access" allowed.

569 Deprecate struct vaapi_context and the vaapi.h installed header.
570 Callers should set AVCodecContext.hw_frames_ctx instead.
572 2017-01-12 - dbe9dbed31 - lavfi 6.69.100 - buffersink.h
573 Add av_buffersink_get_*() functions.

614 Decoders now export the frame timestamp as AVFrame.pts. It was
615 previously exported as AVFrame.pkt_pts, which is now deprecated.
617 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
618 and not the codec timebase.
620 2016-09-28 - eba0414 - lavu 55.32.100 / 55.16.0 - hwcontext.h hwcontext_qsv.h

668 Fix accidental ABI breakage in AVFilterContext.
669 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
671 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
672 compatible with lavfi>=6.47.100. Potentially also affects other users of
673 libavfilter if they are using one of the affected fields.

739 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
740 the reset of the ASS ReadOrder field on flush. This affects the content of

744 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
745 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
746 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
747 The default value for this option will change to "ass" at the next major
748 libavcodec version bump.
750 The current default is "ass_with_timings" for compatibility. This means that
751 all subtitles text decoders currently still output ASS with timings printed
752 as strings in the AVSubtitles.rects[N]->ass fields.
754 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
755 timing is limited to a 1/100 time base, so this is relevant for any subtitles
756 format needing a bigger one), ease timing adjustments, and prevents the need
757 of removing the timing from the decoded string yourself. This form is also
758 known as "the Matroska form". The timing information (start time, duration)
759 can be found in the AVSubtitles fields.

3162 Introduce the avfilter_next() function.
3164 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3165 Change the signature of avfilter_register() to make it return an
3166 int. This is required since now the registration operation may fail.
3168 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3169 Make the pixdesc.h API public.

3193 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3194 Add a pts field to AVSubtitle which gives the subtitle packet pts
3195 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3196 not work right without this.
3198 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3199 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3200 major version. Use AV_PKT_FLAG_KEY instead.
3202 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3203 av_lockmgr_register() can be used to register a callback function
3204 that lavc (and in the future, libraries that depend on lavc) can use
3205 to implement mutexes. The application should provide a callback function
3206 that implements the AV_LOCK_* operations described in avcodec.h.
3207 When the lock manager is registered, FFmpeg is guaranteed to behave
3208 correctly in a multi-threaded application.
3210 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3211 av_free_packet() is no longer an inline function. It is now exported.
3213 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3214 Please use NULL instead. This has been supported since r16506
3215 (lavf > 52.23.1, lavc > 52.10.0).
3217 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3218 The old decoding functions are deprecated, all new code should use the
3219 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3220 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3221 argument instead of a const uint8_t *buf / int buf_size pair.
3223 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3224 Introduce the av_fifo_space() function.
3226 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3227 Move AVPacket declaration from libavformat/avformat.h to
3228 libavcodec/avcodec.h.
3230 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3231 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3232 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3233 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3234 PIX_FMT_BGR32_1 are now macros.
3235 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3236 Re-sort the enum PixelFormat list accordingly.
3237 This change breaks API/ABI backward compatibility.
3239 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3240 Add the enum PixelFormat values:
3241 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3242 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3244 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3245 The Mersenne Twister PRNG implemented through the av_random* functions
3246 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3249 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3250 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3251 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3252 and av_fifo_realloc2.
3253 In addition, the order of the function arguments of av_fifo_generic_read
3254 was changed to match av_fifo_generic_write.
3255 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3256 applications, they may not use sizeof() or directly access members.
3258 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3259 Introduce a new metadata API (see av_metadata_get() and friends).
3260 The old API is now deprecated and should not be used anymore. This especially
3261 includes the following structure fields:
3262 - AVFormatContext.title
3263 - AVFormatContext.author
3264 - AVFormatContext.copyright
3265 - AVFormatContext.comment
3266 - AVFormatContext.album
3267 - AVFormatContext.year
3268 - AVFormatContext.track
3269 - AVFormatContext.genre
3272 - AVProgram.provider_name
