camera
I tried CC last year and stopped using it when I started having webcam issues. A year later, I still have issues with it. I have a Logitech C922 and Blackmagic Capture Recorder. At first, I got the "Camera Busy" with NO other applications running. I tested it, I opened OBS and the C922 turned on no problem. I closed OBS, restarted, went to Device Manager disabled Blackmagic, restarted, opened CC and still the same issue "Camera Busy".
Yes, I went to the 'Switch camera' option, yes I 'Default Camera' too, still same issue. I performed another test, closed CC opened Skype and the C922 turned on no problem. I closed Skype and gave up CC for another program.

Have you continued to have this issue in recent versions of the app? Version 2.0 made substantial improvements in the area of camera selection. Let us know!
