UPnP is a set of specifications for media sharing, playing, remote control, etc, across a home network. The specs are supported by a lot of consumer devices (like smartphones, TVs, Xbox, and PlayStation) that are often labeled as being DLNA compatible or certified.
The DLNA guidelines and UPnP specifications defines several device roles, of which Mopidy may play the role of DLNA Digital Media Renderer (DMR), also known as an UPnP MediaRenderer.
A MediaRenderer is asked by some remote controller to play some given media, typically served by a MediaServer. If Mopidy was a MediaRenderer, you could use e.g. your smartphone or tablet to make Mopidy play media.
There are two ways Mopidy can be made available as an UPnP MediaRenderer: using Mopidy-MPD and upmpdcli, or using Mopidy-MPRIS and Rygel.
upmpdcli is recommended, since it is easier to setup, and offers OpenHome compatibility. upmpdcli exposes a UPnP MediaRenderer to the network, while using the MPD protocol to control Mopidy.
Install upmpdcli. On Debian/Ubuntu:
sudo apt install upmpdcli
Alternatively, follow the instructions from the upmpdcli website.
The default settings of upmpdcli will work with the default settings of Mopidy-MPD. Edit :file:`/etc/upmpdcli.conf` if you want to use different ports, hosts, or other settings.
Start upmpdcli using the command:
upmpdcli
Or, run it in the background as a service:
sudo service upmpdcli start
An UPnP renderer should be available now.
See the Mopidy-MPRIS documentation for how to setup Rygel to make Mopidy an UPnP MediaRenderer.
