seems 2010 new iMac support hardware H.264 acceleration

[clockrun]

Just tried www.youtube.com/apple, and watch the new TV ads in 1080p, and the CPU usage is alwayse below 7% in system monitor.
I remember the last time I went to the retail store and tried last gen iMac 27 with quad-core i5, watch the 1080p ads make one core at full load.

I think apple has enabled the hardware acceleration on AMD's graphics card.

That's because of the new Flash 10.1

The list below, sourced from Flash's engineers and with clarification from us, shows which models of Mac will be able to take advantage of Flash's new hardware acceleration feature:

- MacBooks shipped after January 21st, 2009. In other words, MacBooks with an NVIDIA GeForce 9400M or higher; Intel's integrated GPUs aren't supported.
- Mac Minis shipped after March 3rd, 2009, which have the same GPU situation as the MacBook; earlier Mac Minis had the unsupported Intel GMA 950 GPU.
- MacBook Pros shipped after October 14th, 2008 -- note that this only means the unibody MacBook Pros. The 17" late 2008 MacBook Pro with the old-style non-unibody enclosure has an unsupported NVIDIA 8600M GT GPU.
- iMacs which shipped after the first quarter of 2009; again, NVIDIA GeForce 9400M or higher GPU.

But didn't it say earlier (during the beta) that ONLY NVIDIA chipsets are supported?

Mac OS X hardware decoding support
On Mac computers, hardware decoding of H.264 video in Flash Player is available with Mac OS X 10.6.4 and later on hardware supported by the Mac OS Video Decode Acceleration Framework (such as the NVIDIA GeForce 9400M, GeForce 320M, and GeForce GT 330M). View hardware used by different Mac models. Whether hardware decoding will engage for a specific video is determined by the Mac OS Video Decode Acceleration Framework.

Going to the linked page has this:

The Video Decode Acceleration framework is a C programming interface providing low-level access to the H.264 decoding capabilities of compatible GPUs such as the NVIDIA GeForce 9400M, GeForce 320M or GeForce GT 330M. It is intended for use by advanced developers who specifically need hardware accelerated decode of video frames.

ATI isn't mentioned at all.

It says all iMacs from 2009 and after so I would think ATIs are supported as well. If 2010 iMac is supported, then I can't see why 2009 iMacs wouldn't be.

That video is using the HTML5 player

when you click on the video, the flash menu will pop up. so I think its a flash video
