There is no connected camera message with built in FaceTime camera Anyone run into "There is no connected camera" message while using any of the camera applications (Messages, PhotoBooth, Skype, etc.)? I tried force quitting all the applications that use the camera but with no luck. Even tried sudo killall VDCAssistant without any luck. Restarting the machine fixes the issue, but it is highly annoying to do so every day. I am running 10.8.1 on 2012 MacBook Pro.
From osxdaily:


Quit all open apps that may try to use the FaceTime camera
Open Terminal, found in the /Applications/Utilities directory in OS X
Enter the following command string exactly, then hit return:

sudo killall VDCAssistant

Enter the administrator password when requested, this is required to execute a command with superuser privileges as prefixed by sudo
Relaunch the app that was attempting to use the camera


Or... Use Activity Monitor, search for VDC and force quit it.
