video corrupt on a few frames on MP4 video |
|||||||
Issue descriptionChrome Version: 60.0.3112.7 OS: all This behavior is not observed before. This seems more like a composition bug. xhwang@, can you confirm and assign to composition dev? What steps will reproduce the problem? (1) navigate to https://ats.sandbox.google.com/static/chrome_test_app/index.html (2) play L3_audio_L3_video.mp4.mpd (3) notice at around 0:04~0.05 timestamp, the video frame corrupt, What is the expected result? smooth video frame What happens instead? on 0:04 and 0.05 timestamp, video frame corrupt

give to compositing team. This is observed on both encrypted and clearkey video so it is not a EME specific issue.

Is there a specific OS here to repro on? I'll see if I can repro locally.

yiningc@ can you provide a non-eme repro link? xhwang@ could this just be an issue with the cdm?

It can be reproed using clear key CDM by following the repro step, but add an additional step: (1.5) Choose org.w3.clearkey in "Key system". See the attached screenshot for the "corrupted" frame. Since we can repro the same "issue" with both the codec in the CDM, and FFmpegVideoDecoder, I feel it's an encoding issue. Also, I don't think this has anything to do with compositing.

Yeah generally this happens when keyframes are marked incorrectly and we end up seeking to a non-keyframe.
