* vaapi_encode: Convert to send/receive APIMark Thompson2019-01-23
| | | | | | | | | | | | | This attaches the logic of picking the mode of for the next picture to the output, which simplifies some choices by removing the concept of the picture for which input is not yet available. At the same time, we allow more complex reference structures and track more reference metadata (particularly the contents of the DPB) for use in the codec-specific code. It also adds flags to explicitly track the available features of the different codecs. The new structure also allows open-GOP support, so that is now available for codecs which can do it.

* cbs_h2645: Avoid memcpy when splitting fragment #2Andreas Rheinhardt2019-01-23
| | | | | | | | | | | Now memcpy can be avoided for NAL units containing escapes, too. Particularly improves performance for files with hardcoded black bars. For such a file, time spent in cbs_h2645_split_fragment went down from 369410 decicycles to 327677 decicycles. (It were 379114 decicycles when every NAL unit was copied.)

* avformat/concatdec: always re-calculate start time and durationMarton Balint2019-01-22
| | | | | | | | | | | | | | | | | | | | | This allows the underlying files to change their duration on subsequent avformat context opens. An example use case where this matters: ffconcat version 1.0 file dummy.mxf file dummy.mxf ffmpeg -re -stream_loop -1 -i dummy.ffconcat -f sdl2 none The user can seamlessly change the input by atomically replacing dummy.mxf. v2: Set ConcatFile duration in read_header for all segments with known durations because from now on we always recalculate the start time in open_file, and an instant seek could have caused unset ConcatFile durations.

* avcodec/prosumer: Error out if decompress() stops reading dataMichael Niedermayer2019-01-20
| | | | | | | | | | | | | if 0 is encountered in the LUT then decompress() will continue to output 0 bytes but never read more data. Without a specification it is impossible to say if this is invalid or a feature. None of the valid prosumer files tested cause a 0 to be read, so it is likely not a intended feature.

* avutil: add ROI (Region Of Interest) data struct and bump versionGuo, Yejun2019-01-17
| | | | | | | | | | | | | | | The encoders such as libx264 support different QPs offset for different MBs, it makes possible for ROI-based encoding. It makes sense to add support within ffmpeg to generate/accept ROI infos and pass into encoders. Typical usage: After AVFrame is decoded, a ffmpeg filter or user's code generates ROI info for that frame, and the encoder finally does the ROI-based encoding. The ROI info is maintained as side data of AVFrame. Signed-off-by: Guo, Yejun <yejun.guo@intel.com> Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
