Do you have a GPU?

If he didn't, he would get the message "This demo requires the modern WebGPU graphics API to run. Seems like your browser does not support it."

You don't need a dedicated graphics processing unit to display video from a computer! Back before GPUs were even a thing the framebuffer would just be a region of memory and the video controller would turn that into a signal. Nowadays the latter is assumed to be integrated with the GPU because "who wouldn't need dedicated graphics processing in a desktop"?

I don't have a GPU and it runs fine for me with no errors or messages.
