I have a Raspberry Pi 3 and I would like to use it as an offline media server. Like I want to plug in an USB hard drive with content, and have it served via some media serving application like Kodi as DLNA compliant so my TV can pick it up. I would also like the use the Wifi on the Raspberry Pi 3 as an access point, since I do not have Internet access where the media server is going to be used, so my TV and tablet will need to connect to the Pi 3 wirelessly. I'm not sure how to go about this? Any help would be greatly appreciated.
