Simple Roon extension to display what's playing in each zone. Intended to be used for OBS as an overlay when playing music while streaming.

To use this extension, you will need to run the project's web server on the same network/subnet as your Roon Core. You have two basic options:

1. (Recommended) Build or use the prebuilt Docker image
2. Install Node (https://nodejs.org/) and run the included server

Both options will require a computer that's running all the time, such as a Raspberry Pi. If you have time, feel free to submit a PR to add this to the Roon Extension Manager (https://github.com/TheAppgineer/roon-extension-manager).

Access the now playing information from your web browser (and OBS Browser Source) from http://YOUR-IP:8686/zone-name where zone-name is a slugified version of the Roon zone/player you wish to view.

Note that I don't really intend to make this more configurable at this point due to time restrictions...

Credits to Aiden Wallis - https://github.com/aidenwallis/nowplaying . I pretty much ended up grabbing the HTML, CSS, and Javascript for the client display directly from that project.

Node 14+ or Docker.

• Run npm ci or npm install
• Start the webserver with npm start or node .

cd [folder to save config]
# Note, write permissions for user 1000 are required for the config file
touch config.json
chmod 666 config.json
docker run --detach --restart unless-stopped --name obs-roon-display -v ${PWD}/config.json:/opt/obs-roon-display/config.json --network host docbliny/obs-roon-display:latest

You may also want to change the volume mapping of the config.json file to a persistent location, so that you don't have to re-enable the extension when you update/recreate the Docker container.

There's also an example start script named start-obs-roon-display.sh that might work for you.

Note: The above will not work on macOS due to the way Docker Desktop networking is implemented.

You might need to run docker rm obs-roon-display before restarting.

To stop: docker stop obs-roon-display

To view logs (continuously): docker logs -f obs-roon-display

• Open Roon, and go to Settings / Extensions, find the extension, and then click Enable.
• Open your browser to http://YOUR-IP:8686 and http://YOUR-IP:8686/zone-name.

• Add a new Browser Source
• Set the URL to wherever you're running the extension web server
• Set height to 300 pixels
• Set the width to however wide you'd like the widget to be
• Set the FPS to 60
• Adjust the placement and size on your screen

A successful launch and connection should display the following in the standard output:

Server started on port 8686
Roon core paired

Make sure something is actually playing in the zone. The display won't show up unless the zone is either playing or loading.

Try something like DEBUG=server*,roon:* npm start.

You can add debug logging with by specifying the DEBUG environment variable. Debug namespaces are server (server, server:http, server:socket) and roon (roon:subscribe, roon:update).

If the Roon zone isn't available, you'll get the "404 - Not found" page. However, it has a margin at the top, so that it doesn't accidentally show up in your stream, but you can open the link in your browser and see the error.

You'll also get this page if the extension server has not paired with Roon yet. Check the output to see if you see Roon core paired or not. Verify that the extension shows up in Roon and has been enabled.
