I'm still getting 60% (of one core) CPU utilisation playing HD youtube videos. Playing HTML5 video tag version of the same video, its only about 20% utilisation. As far as I can remember, 60% is about what it was at before, so I'm not really seeing any improvement.
Correct me if I'm wrong, but aren't all Youtube HD videos either H264 (.mp4) or H264 in an .flv container? I don't see why a particular container format would prevent hardware decoding of the H264 video stream.
And if it does, What's the actual improvement in performance?
EDIT: I'm not being sarcastic, I'm really asking... DOES IT WORK?
