1061917 - The HTML5 video full screen animation is pretty jarring

Status: RESOLVED DUPLICATE of bug 1105939

(Core :: Widget, defect)

Description

[(no longer active)]

This is very visible on youtube, but <http://camendesign.com/code/video_for_everybody/test.html> probably gives a better test case.  Both Chrome and Firefox seem to reflow the video during the full screen transition visibly.  They also pause the video playback during the transition.  This is very suboptimal compared to the Flash implementation of full screen video.

Safari seems to do things much better, they keep the video playing during the transition, and there are no visible reflows during the transition either.

Fullscreen bugs normally live in DOM: Core.

Patches accepted.

Yes, but this is OS X specific. We use the OS X fullscreen transition there and that leads to this issue, as best I can tell. Moving to Widget::Cocoa.

Markus/Steven, is there some way we can avoid the transition just for video fullscreens (as in, does Apple let us do that)?

I feel like I've answered this question before ;-)

D'oh. Duping there because of the summary and because it's actually in the right component...
