This is with the latest Nightly on OSX 10.10.1.  The video URL Is <https://www.youtube.com/watch?v=M6RfU9eVaFE>.  This video stopped and restarted after a while several times.  I also noticed the video jumping back to a few seconds earlier (perhaps 2-3s) a few times during the playback.  I will attach before and after screenshots from stats for nerds.

I'm not sure at what point of the video the issues were occurring, but I can't reproduce any problems with the first 3 minutes of video. My guess is that this was fixed by the flurry of fixes over the past few weeks.

Ehsan, can you reproduce in today's Nightly?

Could be, yes.

No but I can never reproduce these issues reliably.  What I can say for sure according to my experience on YouTube is that video playback in newer nightlies works a lot better than it used to.

If you don't think this is actionable please feel free to close it.
