Turn on your computer and click on the "i Chat" icon in the dock.Verify that the green indicator light next to the camera lens is flashing.Not all users have been hit by the blackout though – only webcams that encode in MJPEG and H264 formats have encountered the problem.
The other videoconferencing solution I used is Pana Cast.
Lately, more tech companies are bringing high-end or futuristic videconferencing features to average consumers.
Over the past month, I’ve used two of these: Personify, a software app that utilizes a 3-D camera, and Pana Cast by Altia Systems, which is an expensive standalone camera.
Personify is a free desktop app (download here) that uses computer vision and imaging technology to capture just your head and shoulders, creating a floating bust of you on the screen.
It feels a little like something you’d see in a futuristic movie. First, it hides anything you don’t want people to see in your background, like piles of dirty laundry, a living-room floor covered in kid toys, or the, uh, bathroom walls (admit it).
