Im trying to get full screen video by scaling the canvas up, however the code above only works in Chrome. The video does not show up in firefox 10.0.2 nor safari 5.05. I tried three different files: mp4,ogv, and webm. What’s wrong with my code. I know there is a tag but can I scale it the same way I can with a canvas?
