Why won't my camera work in Facebook video call?
Have a new MacBook Pro running Mavericks. When I tried to use the video call feature in Facebook, it told me I didn;t have the necessary java to execute the install. I downloaded the file suggested online (Java for OS X 2014-001: How to re-enable the Apple-provided Java SE 6 web plug-in and Web Start features) and the install went through. However, when I try to make a call it connects, I can see the other person's video and hear her/him but my camera does not activate (No green light. Person being called can hear me, but no picture appears for them). FaceTime works fine. Skype works fine. Google+ Hangout asks me to give permission to use camera, but hangs up. I also tried to make a FB video call in Safari and that did not work either (same problem).
