Realtime Input with USB Grabber

In this example we will use an Elgato Cam Link 4k video Grabber, but you might use any regular USB Cam.

First install the needed dependencies:

sudo apt-get install v4l2loopback-dkms v4l2loopback-utils v4l-utils v4l2loopback-source v4l2-loopback-utils

Note

While working on a blank workspace, you first need to add a Display and a Canvas, otherwise there will be no option to select your USBCamera source!

Make a workspace like this, and select your USB input:
