Public bug reported: I have been experimenting with youtube videos on html5 technology and the same using flash player. I have noticed that html5 videos tend to be heavy on my processor with CPU usage shooting upto 70% on html5. With flash, however, the usage by fiefox + plugin-container isnt as much.
Also another conclusive proof of more usage is that my computer (slightly old) heats up much more in a html5 video compared to a flash video. This bug is similar to https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/871412 , but different in the fact that I observe poor performance only in html5 videos. (Is this issue perhaps because firefox fails to utilize my GPU, a nVidia 105M running nouveau driver, while flash does use it? Any how I can debug this and add to the report here?)
