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.
One of the videos I used to test: http://www.youtube.com/watch?v=rQ_z-_4fF4Y http://www.youtube.com/watch?v=rQ_z-_4fF4Y
I'm using Safari, and also ClickToFlash for switching between Flash and HTML5 HD video on Youtube. Hardware is a 2009 Macbook Pro 2.53ghz.
- not_an_alien 16y agoDo you see the white square? Some of youtube's videos are FLVs, not H264. This is for H264 only.
- mambodog 16y agoCorrect 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.
