Well, as I said the right thing to do would have been to call
xdg-screensaver, but for that I would have needed to send it the window
ID, which I don't know how to get from VLC.

And since (in my specific setup) that call would pretty much call xset,
I did that directly. If the window ID can be obtained, calling
xdg-screensaver suspend/resume would be a better solution of course.
