I love how they try to make it look like they support two different platforms when they're both exactly one and the same..... and they forgot to add "that run Windows" at the end of the sentence, because netbooks running Linux or OS X are not hardware-accelerated.
Shame, really.
"To date, support for hardware accelerated H.264 video playback in Flash Player has only been possible on Windows PCs and Windows-based netbooks"
And if it does, What's the actual improvement in performance?
EDIT: I'm not being sarcastic, I'm really asking... DOES IT WORK?
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.
Some of youtube's videos are FLVs, not H264. This is for H264 only.
(Although lately the Apple complaints have changed from "make it suck less" to "screw you we don't need you".)
Unfortunately my three year old MBP is too old :( If someone with a newer Mac wants to report back on how well this works, here is a good test video: http://www.youtube.com/watch?v=4N2YWRJ-ppo
