And … sometimes things are simpler than you found. The Droicam devs have made a small linux app too, at https://dev4747apps.com . Download the zip file, unzip it to some folder, run
sudo ./install
It will build an own v4l2loopback-dc for your kernel, configure it for loading and after a reboot you’ll have
- A new /dev/video loopback device
- A small program in the folder you installed from called ‘droidcam’ and even ‘droidcam-cli’. The first one is nice since it lets you autofocus and zoom in/out. Provided the Droidcam app on your phone runs.
So basically the app on phone and linux are enough to get it working.
