May I ask: are you sure you need a media center with transcoding? Because it may be totally sufficient for you to access files through a file explorer and play them with VLC/mpv or whatever else. Having a media center is only really useful if you need external access to your media. I set all that stuff up once, then realized i never watch shows/movies on the go. And if I do, i know beforehand and can copy the raw files to the device i plan to watch on.
