No Camera in Skype

I have Retina MBP with 10.9.1 installed Mac OS X.

I have Skype 6.12. I'm not using video camera everyday ;) but I'm using Skype every day, and someday when I need it in Skype I saw that it was not detected, so I can't use it. From that point I've started to monitor that situation. And I've found that every time after while the camera is gone...

At the moment the solution is an OS X restart, but I don't like that solution.

Is there any other solution, or any possibility to get know why the system is losing access to the camera.

By the way, when the camera is lost, it is also not available in any other software like: Viber, Photo Booth, Facetime etc...


This command from shell:

sudo killall VDCAssistant

restores the camera for me every time.
