UniversalMediaServer is a DLNA-compliant UPnP MediaServer. It is capable of sharing video, audio and images between most modern devices. It was originally based on PS3 MediaServer by shagrath, in order to ensure greater stability and file-compatibility.
UniversalMediaServer supports all major operating systems, with versions for Windows, Linux and Mac OS X. The program streams or transcodes many different media formats with little or no configuration. It is powered by MEncoder, FFmpeg, tsMuxeR, AviSynth, MediaInfo, VLC, OpenSubtitles.org and more, which combine to offer support for a wide range of media formats.
