It appears that my webcam isn't listed in "Select Camera Device", what do I do now?

Hi and welcome to the forum :wink:
(Going by your way of asking)

To give any meaningful advice, you need to help others to help you:

  • Describe in as much details what application you are using, so people who want to help (or are able to) know where you don’t get that selection.
  • Provide info about your hardware
