I have a Logitech C920 webcam connected to my pi3. I can view the camera feed on console using VLC. Can't get a feed using "Camera" in HiveControl. I just get the little square with the question mark. USB camera is enabled in devices. I'm wondering if I need to establish a stream in VLC? I played around with the stream settings for several hours last night trying to establish an http stream but couldn't connect from other computers.
