DLNA is a widely used, popular media sharing protocol for instant multimedia sharing across devices irrespective of the hardware/software platform they are running. To get DLNA working we need a server, which catalogs and serves the multimedia content for consumption, while a client consumes the content supplied by the DLNA server. MiniDLNA is a fast, simple to configure and easy to use DLNA server which can be installed in minutes on the Raspberry Pi, however it has limited features.
Plex Media Server is yet another powerful DLNA multimedia server, the good news is - we now have a working Raspberry Pi port of Plex home theater as RasPlex. RasPlex enables users to enjoy multimedia content across every DLNA capable client on their home network, utilizing the Plex Media Server's friendly user interface.
