I’ve discovered that this works (at least with Chrome and Firefox). What I did was went to the device manager and right clicked the camera (not manycam, but the actual camera) and clicked “disable”… I think it makes the websites think that manycam is your real cam since your real cam is disabled? Just a guess.
Oddly, though - I can’t get this to work in the Opera browser. It gives error with camera message. Is anyone able to successfully use manycam with the opera browser?
