Does it worked before, or is it a fresh install?

Looks like ffprobe (is part of ffmpeg) is missing.

Run: sudo apt install ffmpeg

That was part of the solution.
I actually reinstalled the entire program because previously only a few images were displayed repeatedly, and I didn't know why the others weren't.
But now, despite reinstalling, videos still won't play. The start screen appears, but the video is choppy for a very short time, and then the screen changes again.

Any more ideas?
