Question is 'Does it actually work?'

And if it does, What's the actual improvement in performance?

EDIT: I'm not being sarcastic, I'm really asking... DOES IT WORK?



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

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.


Do you see the white square?

Some of youtube's videos are FLVs, not H264. This is for H264 only.


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.
