That's nice and well when we're talking about desktop systems. But think about MythTV media center PCs - if you could combine an Atom CPU and a passively cooled nVidia or AMD GPU, a super-silent, HDTV capable home-grown set-top box would be possible.

Of course, an OpenCL encoder would help, too, for this kind of setup - broadcast TV encoding, for example.

According to heise.de (in German), nVidia says that OpenCL applications will run seamlessly on any gpus with a CUDA-compliant driver. Does anyone know if that applies to the proprietary Linux drivers?

If this really takes off, how long until the hardworking people from the x.264 or VLC or ffmpeg or mplayer projects can write a H.264/AVC decoder that uses the GPU?
