Once it's up and running, all you really need to do is set up folders you'd like to share: music, pictures, whatever.

The program is powered by assorted other open-source applications - FFmpeg, MEncoder, tsMuxeR, MediaInfo, OpenSubtitles - but you don't need to have any of these beforehand. Supported devices include Sony PlayStation 3 (PS3) and PlayStation 4 (PS4), Microsoft Xbox One and 360, many TVs (Samsung, Panasonic, Sony, Vizio, LG, Philips, Sharp), smart phones (iPhone, Android, etc.), Blu-ray players, and more.
Universal Media Server is a Java-based server which can stream video, audio or pictures to any DLNA device.
