Like you, I was also going to suggest it was related to video drivers, but given that you have high CPU usage when playing an OGG file, that can't be the cause.
I suspect that this is your problem: Intel(R) Atom(TM) CPU N270 @ 1.60GHz That's not a very powerful CPU. And if I recall correctly, your Intel Corporation Mobile 945GME Express Integrated Graphics Controller is too old to support VA-API. However if the video plays smoothly I wouldn't worry about it. Just don't try to do much else while playing the video. At 60%, you should be able to do other things while listening to an OGG. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/871412 Title: more than 80% cpu usage when watching youtube video (flash or html5) firefox and chromium To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/871412/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
