Please describe your issue below:

I’m running Khadas Ubuntu 5.4.180 as a headless server and would like to access the VPU to encode files or use Hardware Encoding / Transcoding, but without GPU (framebuffer drivers) installed I cannot access the VPU. Aside from installing a DE, what is the best way to access and use the VPU?
