I want to play a video in a way that the only way to close it is shutting down the computer forcefully. Meaning: I'd like it so that interacting with the video playing is impossible.

Is that even possible? If so, how should I do it? I've been thinking of making the video play when it's shutting off, that way, you shouldn't be able to close it. However, I do not know the dependencies needed for a video player to work and, as such, it would be difficult to set up. Is there a better solution than this?
