Windows 7 Pro SP1
BitDefender Internet Security Build 25.0.19.73 Last Updated 4/16/21
Skype 8.71.0.36
Logitech C920 USB Webcam
Shortly after the 4/16/21 update, Skype began to misbehave. Specifically, if I initiated a call, the webcam would come on as expected, but once the recipient answered and the call connected, my camera would turn off. The microphone was still active. I could see and hear the recipient, they could hear me but not see me.
This scenario was 100% repeatable.
Changing USB ports, deleting the webcam and readding the webcam, removing and reloading Skype had no effect.
Going to Video & Audio Protection and setting Webcam Access = OFF returns Skype to normal behavior.
Testing the other webcam settings with Webcam Access = ON did not yield correct results; the only workaround for this appears to be to keep Webcam Access = OFF.
It is unknown if Skype is similarily affected on other Windows Operating Systems.
