    How to zoom in and out with a webcam

    I am using a Logitech C930E webcam on Ubuntu 20.04. How can use the webcam’s zooming feature? Can I invoke this zooming feature in Cheese, Zoom, etc.?

    Code:
    v4l2-ctl -d /dev/video0 -c zoom_absolute=200
    This assumes the Video-4-Linux v2 device is /dev/video0.
    Works on a Logitech C920 Pro.
