Display c920 video

[[Pluvious]]

As an "old timer", I have recently become interested in DATV following attendance at the Wirral Convention a few months ago.
Spurred on by my success with the MiniTiouner V2 receiver have decided to have a go with the Portsdown/Lime SDR mini 2019 TX.
Have assembled some of the basic items and recently purchased a Logitech c920 Pro webcam and its connected to a USB port on
the Raspberry Pi / 7inch touchscreen combination. I was expecting to be able to view the webcam video output on the touchscreen.
I have tried various combinations of buttons from within the menu selections but have failed display any video from the webcam.
I have looked at various topics on the Forum and other BATC web pages and failed to find any helpful guidance relating to this aspect.
I would welcome any advice.
Have tested the c920 on a Win10 laptop with Skype and it works fine.

The USB camera does not display on the touch screen, only the PI Camera.
