6 months ago As far as I understand how libvmaf handles CUDA, that's impossible. It links directly against CUDA, making an installed Nvidia-Driver a requirement to run the binaries. This is unacceptable for hopefully obvious reasons.
Plus, it needs the CUDA SDK to build, which would just like that more than triple the size of every single build image.
Please correct me if I'm wrong and there is some way to make it dynamically load the library and build without the full SDK.

Can you please add support for libvmaf_cuda in the builds ?
