Feature summary

Would it be possible for mpvpaper to take a screenshot of the current video wallpaper to use for the overview background?

Motivation / use case

I think such a feature would improve the visual appeal quite nicely!

Proposed solution

I know the DMS mpvpaper plugin does this using ffmpeg, so I would assume that method could be applied here.

The proposed PR isn't exactly the solution you're suggesting. I've done some research on how it works in dms, and perhaps a similar approach could be implemented by setting the frame corresponding to the moment the video stops as the wallpaper, but it's more complex than what I'm currently proposing.
