YouTube Thumbnails Constantly Overridden

[Elarem]

Apologies if this is not the correct location to discuss plugin problems.

I'm currently implementing a library for YouTube videos I've downloaded via yt-dlp and am encountering this strange error with the Jellyfin YouTube Metadata Plugin.

Everything scans as expected, with the video thumbnail automatically getting pulled in per the library's fetcher settings, even using Screen Grabber as a fallback for thumbnails that can't be fetched as seen in the last video in the list.

   

However, after an undetermined period of time, the thumbnails always, consistently, reset to all be the thumbnail from the first video in the library based on alpha order.

   

Looking into the metadata settings of each video, the YouTube ID still correctly points to the video in the External IDs section, and all other metadata scrapped from YouTube (the release year, the creator, the video description, etc.) all seem to be preserved as expected.

   

Rescanning the library and replacing all existing metadata restores the correct thumbnails, but only for a brief period before it resets again.

Has anyone else encountered/solved this? I've been scratching my head at this for a while and appreciate any help!

Do you have NFOs in your media directories? Or an external app that places images with your videos?

Not 100% sure if I know what you mean by NFOs in the media directories, but in the library's settings, the Nfo checkbox in the Metadata Savers section is selected.

I don't have an external app that places images with the videos.
