MPD (mopidy) like all-round media server?

I’m using Mopidy and M.A.L.P - Android MPD Client to play music from my home server on my stereo… I like the simplicity of this.
I was wondering if there is anything like this that supports video formats and photos? So that I could make it like full media server. Maybe some plugin for freenas/openmediavault or smth. like that?
Could you recommend me some software to try? Can plex do this, I’ve never used it. I don’t want to stream content.
