Some mobile systems, especially Optimus enabled ones, do not have access to the NVIDIA Video Processing features. Consult your laptops manufacturer if its supposed to be available.

Argh, this is the only reason I chose the 06:00.0 3D controller: NVIDIA Corporation GM108M [GeForce 930M] (rev a2) upgrade option on my T460s. :/

I have the exact same situation on my T560.
As the Intel-GPU already has a video unit, they hard-disabled or even removed the one of the Nvidia card.
Talked with the Lenovo support about this, I'm not sure if they even understood what I was talking about, but there apparently is no way to do anything about this.

Anyway, not a bug in ffmpeg, nor anything it could do to help with the situation.
