This nodejs script allow the user to view the time remaining of a video running on Vmix through a web page that can be opened by anyone on the network.
Before we can run the Node server you will need to have the application installed on your device.
git clone https://github.com/x3rud/Vmix-Video-Timer.git
Next, change directory into that folder using the following commands to install all of your projects dependencies.
cd Vmix-Video-Timer
npm install
Now, make sure everything is working by starting up your Node server.
node index
Open the environment.json file and set there the ip of vmix instance with the port (eg.: 192.168.1.79:8088)
Once done connect to:
http://localhost:3000
The prerequisite is to have a Raspberry PI with a Raspbian distro on it. Follow the previous instruction to setup the node server.
Now you can go ahead and create a server file. Create this in the systemd directory using the following command:
sudo nano /etc/systemd/system/node-server.service
And insert
[Service]
WorkingDirectory=/home/pi/Vmix-Video-Timer
ExecStart=/usr/local/bin/node --expose-gc /home/pi/Vmix-Video-Timer/index.js
Restart=always
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=nodeServer
User=root
Group=root
Environment=NODE_ENV=production
[Install]
WantedBy=multi-user.target
Exit nano with ctrl + x and press Y to save the file. You can then activate the system file with the following command:
sudo systemctl enable node-server
To check that it worked, reboot your Pi using sudo reboot and once it has loaded back up, use the browser navigate to the port that your server usually runs on http://localhost:3000.
Make shure to have ./config/lxsession directory, if not run:
cp -r /etc/xdg/lxsession ~/.config/
The last step in the process is to boot the chromium-browser into kiosk mode to show your Node application full screen. To do this you need to add one line of code to the autostart file. To edit your autostart file, use the following command:
nano /home/pi/.config/lxsession/LXDE-pi/autostart
Add the following line to the bottom of the file. The --kiosk flag removes the frame and makes it full screen. The --incognito means that it doesn't remember sessions, so if you pull the power chord out of your Pi, you won't get a warning next time you boot up Chromium. Remember to change the port to whatever your node server is running on. If you're not running a node server, you can change the http address to any website address.
@chromium-browser --kiosk --incognito http://localhost:3000
If you want to remove the mouse pointer you can install unclutter and again add that to the autostart file. Install unclutter using the following command:
sudo apt-get install unclutter
Again, open your autostart file:
nano /home/pi/.config/lxsession/LXDE-pi/autostart
and add the following line to the bottom:
@unclutter -idle 0.1 -root
