Funding

dms is looking for funding for further development. See https://github.com/sponsors/anacrolix and the issues list if you have something specific in mind. Thank you for your support!

dms

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.

Installing

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

Running DMS using Docker

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

Running DMS as a systemd service

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

Running DMS as a FreeBSD 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

-config string	json configuration file
-deviceIcon string	device icon
-fFprobeCachePath string	path to FFprobe cache file (default "/home/efreak/.dms-ffprobe-cache")
-forceTranscodeTo string	force transcoding to certain format, supported: 'chromecast', 'vp8'
-friendlyName string	server friendly name
-http string	http server port (default ":1338")

-path string	browse root path
-stallEventSubscribe	workaround for some bad event subscribers
-transcodeLogPattern	pattern where to write transcode logs to. The [tsname] placeholder is replaced with the name of the item currently being played. The default is $HOME/.dms/log/[tsname]. You may turn off transcode logging entirely by setting it to /dev/null. You may log to stderr by setting /dev/stderr.

Dynamic streams

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 -"
     }
  ]
}

By default, dynamic content is treated as video. It is possible to specify a "Type" parameter with value "audio" or "video" to explicitly set this.
