x264 and Stream Processors

[xc3ll]

I was wondering if there was any work being done on x264 to get it working with nvidia's CUDA technology. It would be great to get that working. If there isn't any current development, or it's still in the beta stages, I'd like to participate. I can do testing(have an 8800gts), as well as write some code(I don't know how x264 works--I should take a peak at the source--but I can write code pretty well).

was going to post this in the development thread, but its locked :(

I'm sure your input would be very welcome! just ask akupenguin on here, he's the x264 author.

I don't have a good idea of the latency and bandwidth avilable for communicating between cpu and gpu, and without that I can't properly evaluate the chances of different methods. But the most likely so far is: Offload motion search (me.c and half of analyse.c) to the gpu. Run intra search on the cpu at the same time. Then merge those results and do the rest of the encoding of the macroblock in pure cpu.
