I'm trying to view YouTube videos embedded in Facebook pages on fullscreen. I am on Chrome and the videos are playing in the HTML5 player. When I hit fullscreen, the browser itself goes full screen and the video is nowhere to be seen.
This does not happen when I'm on Youtube, so it doesn't seem like a browser specific problem. On other websites (I tried mental floss and twitter), embedded videos play on the HTML5 player, but do not show the Fullscreen option.
What could be the problem here?
