What it is

UniversalMediaServer is a DLNA, UPnP, and HTTP(S) media server written in Java and released under GPL-2.0. It shares video, audio, and images between most modern devices. The project lives in the Content & Publishing / Digital Asset Management ecosystem and presents itself as a media-server application for local network distribution.

It solves the concrete problem of making stored media available to different client devices without requiring each device to handle every file format. The server can stream or transcode many different media formats with little or no configuration. It was originally based on PS3 Media Server by shagrath, with the stated aim of greater stability and file compatibility.

Key capabilities

• It provides DLNA, UPnP, and HTTP(S) serving paths for media clients on a network.
• It shares video, audio, and images rather than only one media type.
• It supports Windows, Linux, and macOS, so the server can run on the major desktop and server platforms named in the README.
• It can stream or transcode many different media formats, using external media tools such as FFmpeg, MediaInfo, MEncoder, tsMuxeR, AviSynth, and VLC.
• It is designed to require little or no configuration for common media-sharing use, while still exposing a broad format-support surface.
• It is an open-source Java project under GPL-2.0, with public GitHub releases, an issue tracker, and a forum listed as project links.

Who uses it and how

• Users install UniversalMediaServer on a Windows, Linux, or macOS machine and point it at local media files.
• Users access those files from modern devices through DLNA, UPnP, or HTTP(S) rather than manually copying media to each device.
• Users rely on the server to choose between direct streaming and transcoding when a client cannot play a file in its stored format.
• Users benefit from the integration of FFmpeg, MediaInfo, MEncoder, tsMuxeR, AviSynth, and VLC when working with a wide range of media formats.
• Contributors use GitHub forks, feature branches, tests, and pull requests to propose changes, while translations are associated with Crowdin.

Getting started

Download an official release for Windows, Linux, or macOS from the project releases page and run the server on the host that stores the media. The provided README does not mention a Docker image, package manager, or hosted deployment method.

When to use it — and when not to

Use UniversalMediaServer when you need an open-source, cross-platform DLNA, UPnP, and HTTP(S) media server for video, audio, and images. Avoid it when you want a hosted option, because the provided facts describe downloadable releases and self-run media tools rather than a hosted option. The 405 open issues, long project age, and reliance on many external media components indicate that self-hosting can require ongoing maintenance, troubleshooting, and format-specific adjustment.
