Roku thumbnail images have to generate every single time the app is opened? - jellykrabbypatty - 2025-11-03
Is it normal for Jellyfin to have to reload the movie covers every time the Roku app is opened and closed, or for it to scroll for a few seconds and pause wheeling when you scroll down too fast? I just want to make sure I didn't do anything wrong or if there is anything I can fix/optimize. I am fairly sure my permissions are correct. I gave myself ownership and 755 and gave the user jellyfin permission to read and write.
Also, the initial loading of my Music and Home Video libraries takes almost a very long time on any client since updating to the new server.

Yes, this is normal. I see the same behavior. Items within a library are loaded in fixed-size batches (60 at a time), and the next batch is not loaded until you have scrolled down to near the bottom of the list of items that have been loaded already. The batch size is hardcoded, with no way for a user to change it using the Roku client.
You could file an issue on the jellyfin-roku github to request a feature allowing users to change the batch size.

Ok, I see. I did get a little speed improvement by setting my caddy to compress the thumbnail files some, but it still does the freeze and load thing when going down.
You'd think if you were sitting on the page, the app would go ahead and load whats coming up next instead of waiting for you to scroll down and waiting while it loads. Maybe it is a technical limitation or something.
My music albums take almost a minute to load initially when opening the library. I don't know what that's about. Only happened since the update.
Thanks for your help!
