Thanks again for your kind reply. Although I’m not a lawyer myself, I know
that if you’re the sole(!) author of the yadif_cuda kernel source, then you
would be allowed to publish that code under any additional license you want.
But that would be your very own decision, I wouldn’t dare to ask you about
doing so. ;-)
Another way might be local compilation via NVRTC or NVCC, but this would
require the CUDA SDK to be installed. I guess you’ve already thought about
