### Describe your suggested feature

There should be an option to use external player only when playing local anime.

### Other details

I have noticed that whenever I'm using an external player (VLC), the anime that I have downloaded from other sources doesn't play. But whenever I turn it off, the local anime that I have saved on my local source wouldn't play. That's why it would be good if there's an option to use external player only when playing local anime instead of having to turn on and off the external player whenever I'm switching from watching local anime to downloaded anime.
