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
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

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 . |
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.
