Since you run both, I have a few questions if you don't mind.
I don't have a plex pass but, so the only feature I want is intro skipping and from what you mention I understand it needs tinkering. Acceptable for me.
My usage is pretty simple if I migrate to Jellyfin do I need to fuck around with my folder structures ? No special case just /movie/title | tv/title in my use-case with the usual arr stack for grabbing.
The client used currently is a desktop client on arch/windows and I don't need hardware transcoding. The server and libraries are on Truenas.
I don't need remote playback for movies/tvs but I have no idea how to replace Plexamp and if you have suggestions, feel free to mention it.
Is BCAA different from normal protein powder?
Also, why does it taste better for you?
