Suspecting: r609300 ?
@Tommy Steimel: Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner.

Note: 
1. Unable to provide 'per-revision' bisect as it shows "We don't have enough builds to bisect" error message for above range. (tried on other machines but still getting the same error again)
2. Unable to perform Chromium bisect as video does not play on chromium builds.
3. Hence providing suspect manually.

Kindly refer the below attached screen cast.

Thank You!
