Please correct me if I'm mistaken, but it seems like Yazi is saving video thumbnails only for the current session. Depending on the amount of (video) files this can grow into a major bottleneck. Especially when using the Wrapper.

LF and Ueberzug++ are solving this by storing the generated thumbnails in the users tmp/cache directory and using those as a source (via the videos path afaik) before calling ffmpegthumbnailer again. That's ofc much quicker.

I believe that could be a good approach to follow by yazi too?
