GPU accelerated trans-coding

What was provided was only a decoder for nVidia GPU and not a transcoder. If you're talking about a transcoder then it will need to be written to take advantage of OpenCL - IIRC Mainconcept makes a h264 OpenCL powered encoder.

1. The Apple H.264 decoder supports more than just NVIDIA GPUs:
"This reference describes the Video Decode Acceleration framework available on Mac OS X v10.6.3 and later with Mac models equipped with the NVIDIA GeForce 9400M, GeForce 320M, GeForce GT 330M, ATI HD Radeon GFX, Intel HD Graphics and others."

2. QuickSync inside of Sandy Bridge CPUs can provide hardware accelerated transcoding.

 

Thank you for the correction - the last time I checked (would have been over a year ago) it only covered nVidia GPU's at the time - since then it has been updated 2 times in 2011.

Assuming such functionality is exposed within Mac OS X - whether it is easier for programmers to tune for AVX or just jump into OpenCL 1.1.

 

Haven't heard of anything using OpenCL yet, even on Windows.

I love the idea though.

And there for a while, Apple was making sure all their PCs had real GPUs...until recently. Made it seem like they were going to do something big with OpenCL, but...then nothing happened.

 

Here is some information from Mainconcept:

Oh cool-didn't know anyone was (supposedly) using it...

Except it's weird, given that they reference AMD's proprietary thing, keep calling it ATi, and if it was really OpenCL...well, the whole point is it would run on both, and Nvidia provided OpenCL support first.

But at least they are supporting both one way or the other.

Wish Intel wasn't including video and this "quicksync" stuff though...they appear to be wasting enough space for a fifth core, or a ton more cache
