AMF is AMD's equivalent to NVENC. I think if you aren't running an AMD card, you won't have the necessary libraries?
Ah yes, that would be it. Thanks! I threwa quick C++ program together to do something similar using FFMPEG.
Yea, I haven't really needed an NVENC version yet. Will probably add it... eventually... for my laptop. Shouldn't be too any more difficult than just swapping out the right parts, though.
