417 which can create the decoder context and allocate hardware frame automatically.
418 See AVCodecContext.hw_device_ctx and AVCodecContext.hw_frames_ctx. For D3D11,
419 the new AV_PIX_FMT_D3D11 pixfmt must be used with the new API.

459 parameter type to size_t at next major bump.
461 2017-05-05 - c0f17a905f - lavc 57.94.100 - avcodec.h
462 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
463 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
464 set the Cuda device handle.
466 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

474 and av_content_light_metadata_create_side_data() API, and AVContentLightMetadata

490 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
491 (via an entry named "rotate"). Use av_stream_get_side_data() with
492 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
493 av_display_rotation_get(). The same is done for muxing. Instead of adding a
494 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
495 to be added to the AVStream.

510 Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
511 bump, and libavformat will behave as if it were always set.
512 Deprecate av_packet_merge_side_data() and av_packet_split_side_data().
514 2016-03-20 - 8200b16a9c - lavu 55.50.100 / 55.21.0 - imgutils.h

521 2017-03-18 - 3796fb2692 - lavfi 6.77.100 - avfilter.h
522 Deprecate AVFilterGraph.resample_lavr_opts
523 It's never been used by avfilter nor passed to anything.

530 2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
531 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
532 native decoder format. (The default value is not changed.)
534 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
535 Remove requirement to use AVOption or accessors to access certain fields
536 in AVFrame, AVCodecContext, and AVFormatContext that were previously
537 documented as "no direct access" allowed.

554 2017-01-17 - 2a4a8653b6 - lavc 57.74.100 - vaapi.h
555 Deprecate struct vaapi_context and the vaapi.h installed header.
556 Callers should set AVCodecContext.hw_frames_ctx instead.
558 2017-01-12 - dbe9dbed31 - lavfi 6.69.100 - buffersink.h
559 Add av_buffersink_get_*() functions.

600 Decoders now export the frame timestamp as AVFrame.pts. It was
601 previously exported as AVFrame.pkt_pts, which is now deprecated.
603 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
604 and not the codec timebase.
606 2016-09-28 - eba0414 - lavu 55.32.100 / 55.16.0 - hwcontext.h hwcontext_qsv.h

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

722 that is not the case.
724 2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
725 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
726 the reset of the ASS ReadOrder field on flush. This affects the content of
727 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
730 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
731 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
732 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
733 The default value for this option will change to "ass" at the next major
734 libavcodec version bump.
736 The current default is "ass_with_timings" for compatibility. This means that
737 all subtitles text decoders currently still output ASS with timings printed
738 as strings in the AVSubtitles.rects[N]->ass fields.
740 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
741 timing is limited to a 1/100 time base, so this is relevant for any subtitles
742 format needing a bigger one), ease timing adjustments, and prevents the need
743 of removing the timing from the decoded string yourself. This form is also
744 known as "the Matroska form". The timing information (start time, duration)
745 can be found in the AVSubtitles fields.

3150 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3151 Change the signature of avfilter_register() to make it return an
3152 int. This is required since now the registration operation may fail.

3179 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3180 Add a pts field to AVSubtitle which gives the subtitle packet pts
3181 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

3184 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3185 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3186 major version. Use AV_PKT_FLAG_KEY instead.
3188 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3189 av_lockmgr_register() can be used to register a callback function
3190 that lavc (and in the future, libraries that depend on lavc) can use
3191 to implement mutexes. The application should provide a callback function
3192 that implements the AV_LOCK_* operations described in avcodec.h.
3193 When the lock manager is registered, FFmpeg is guaranteed to behave
3194 correctly in a multi-threaded application.
3196 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3197 av_free_packet() is no longer an inline function. It is now exported.
3199 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3200 Please use NULL instead. This has been supported since r16506
3201 (lavf > 52.23.1, lavc > 52.10.0).
3203 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3204 The old decoding functions are deprecated, all new code should use the
3205 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3206 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3207 argument instead of a const uint8_t *buf / int buf_size pair.
3209 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3210 Introduce the av_fifo_space() function.
3212 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3213 Move AVPacket declaration from libavformat/avformat.h to
3214 libavcodec/avcodec.h.
3216 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3217 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3218 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3219 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3220 PIX_FMT_BGR32_1 are now macros.
3221 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3222 Re-sort the enum PixelFormat list accordingly.
3223 This change breaks API/ABI backward compatibility.
3225 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3226 Add the enum PixelFormat values:
3227 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3228 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3230 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3231 The Mersenne Twister PRNG implemented through the av_random* functions
3232 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3235 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3236 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3237 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3238 and av_fifo_realloc2.
3239 In addition, the order of the function arguments of av_fifo_generic_read
3240 was changed to match av_fifo_generic_write.
3241 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3242 applications, they may not use sizeof() or directly access members.
3244 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3245 Introduce a new metadata API (see av_metadata_get() and friends).
3246 The old API is now deprecated and should not be used anymore. This especially
3247 includes the following structure fields:
3248 - AVFormatContext.title
3249 - AVFormatContext.author
3250 - AVFormatContext.copyright
3251 - AVFormatContext.comment
3252 - AVFormatContext.album
3253 - AVFormatContext.year
3254 - AVFormatContext.track
3255 - AVFormatContext.genre
3258 - AVProgram.provider_name
