Details

Environment:
MacOS Sierra, nightly 55.0a1 (2017-05-25) (64-bit)

STR:
1. Go to Youtube
2. Click any video to play
Check the "stats for nerds" for "Dropped Frames:"

Actual result:
video frames keeps dropping and playback are unacceptable to watch.
JW,
Could you help check it? It looks like frames dropped due to AV unsync.

What about:support shows?
What resolution?

What kind of mac is it?
I cannot see this problem in Taipei office now... yesterday I hit this problem at home and it was not seen on Chrome. I am going to test it today at home again.

The resolution is ~720P, not higher resolution. I should have captured the "stats for nerds".

MacBook Pro (Retina, 15-inch, Late 2013)

you should be served H264 in mp4, which would be hardware accelerated
Close this bug since I have not seen it anymore. Probably there was firefox update downloading in the background.
