dms is a UPnP DLNA Digital Media Server. It runs from the terminal, and serves content directly from the filesystem from the working directory, or the path given. The SSDP component will broadcast and respond to requests on all available network interfaces.

dms advertises and serves the raw files, in addition to alternate transcoded streams when it's able, such as mpeg2 PAL-DVD and WebM for the Chromecast. It will also provide thumbnails where possible.

dms also supports serving dynamic streams (e.g. a live rtsp stream) generated on the fly with the help of an external application (e.g. ffmpeg).

dms uses ffprobe/avprobe to get media data such as bitrate and duration, ffmpeg/avconv for video transoding, and ffmpegthumbnailer for generating thumbnails when browsing. These commands must be in the PATH given to dms or the features requiring them will be disabled.

Assuming $GOPATH and Go have been configured already:

$ go get github.com/anacrolix/dms

Ensure ffmpeg/avconv and/or ffmpegthumbnailer are in the PATH if the features depending on them are desired.

To run:

$ "$GOPATH"/bin/dms

dms is distributed as Docker Image. Serve Media in /mediadirectory using `dms`:

docker pull ghcr.io/anacrolix/dms:latest
docker run -d --network host -v /mediadirectory:/dmsdir ghcr.io/anacrolix/dms:latest

A sample systemd .service file has been provided to assist in running DMS as a system service.

Install the provided service file to /etc/rc.d or /usr/local/etc/rc.d add dms_enable="YES", and optionally dms_root="/path/to/my/media" and dms_user="myuser" to your /etc/rc.conf

DMS supports "dynamic streams" generated on the fly. This feature can be activated with the -allowDynamicStreams command line flag and can be configured by placing special metadata files in your content directory. The name of these metadata files ends with .dms.json, their structure is documented here.

An example:

{
  "Title": "My awesome webcam",
  "Resources": [
     {
        "MimeType": "video/webm",
        "Command": "ffmpeg -i rtsp://10.6.8.161:554/Streaming/Channels/502/ -c:v copy -c:a copy -movflags +faststart+frag_keyframe+empty_moov -f matroska -"
     }
  ]
