[Mug Funky]

So I've been slowly learning vapoursynth for some freelance work i'm doing (I went away from encoding for a while back before vapoursynth has matured, so I never put serious time into it until now).

for various reasons I've decided to make my main encoding machine a VM running in virtualbox. Why? so I can keep everything in ubuntu instead of trying to build ffmpeg + vapoursynth + all the plugins + x264-10 + x264-8 + x265 etc etc all while accounting for different commandlines in windows, osx and ubuntu. I can also migrate to EC-2 instances when things need to scale.

so... I've noticed a few filters are running on GPU, which is great! but i'm in virtualbox and swapping between different host machines with different capabilities.

does anybody know a friendly way to get OpenCL to run on CPU in ubuntu? I've had a brief google but most guides just don't account for the VM environment - they assume you will be on bare metal, and only the 1 machine.
