I know about LibreELEC and Kodi/XMBC because I used them years ago. I didn't know about Emby, suggested in another reply. I'm a little wary about those systems especially if backed by a company. Maybe they'll go fully commercial or shut down and I'll have a system to rebuild and relearn. I don't see much value in those interfaces, I won't pay for one. I prefer a bare file system and VLC. They'll be available forever.
