I have a C920 Pro. None of the easy-to-use software does the panning, but OBS can. OBS is pretty much overkill and you have to setup a virtual webcam (kernel module) for the video conference software to see. OBS generates the output for that virtual webcam. OTOH, with OBS, you can generate any special effects you like regardless of what the conferencing tool supports or doesn't support. Want to have a green screen setup with you warping through space or sitting on a white-sand beach in the Carribean? Not a problem.
There is also a CLI tool to send V4L2 commands ...
Code:
$ v4l2-ctl -d /dev/video0 -c zoom_absolute=200
$ v4l2-ctl -d /dev/video0 -c brightness=100
are the ones I use, but there has to be 50 other -c options.
