I have a laptop with Ubuntu 17.10 and skypeforlinux 8.16.76. The laptop has a built-in webcam and I have connected a Logitech QuickCam IM To a USB Port (I need to use an external cam for flexibility reasons).
With the old skype 4.3, the external webcam was working very well. Now, with the skypeforlinux version 5.4 onward, the external webcam shows black frame. To be clear, the "Audio and Video Settings" shows both the cams, but when I select the external webcam, it shows black frame. The internal webcam works perfectly fine. On Windows, both the cams work fine. Also, in Cheese, both the cams work fine.

What do I need to do to get skypeforlinux working with the external cam?
