[MediaError] MediaMSEError: 11 while playing av8185201 @ Chrome 56.0.2924.87 (64-bit)

[jcpwfloi]

Environment

• Operating System: Mac
• Browser Version: Chrome 56.0.2924.87 (64-bit)
• Error occurs when: 4:18

Description

This error displays when playing av8185201 in the environment above at 4:18. However, firefox doesn't seem to have this issue. I guess this is because of something weird from flv.js or chrome MSE API thus further test should be done to position the error.

There may be corrupted video frame in the stream which caused decode error in chrome's media pipeline.

I'll check the video in a few days.

I suggest that skipping random frames while encountering decode error may help resolve the entire crash.

After media segment being appended into MSE sourcebuffers, It is no longer editable or skipable.
When decode error occurred, the media pipeline has been destroyed and unrecoverable.
