I tried the steps recommended and it did fix my camera, but then the sound disappeared.
So I can either see the person I am calling, with the old version of Skype, or hear him, with the new version.
Frustrated.
Here is what I did to restore the camera, then the sound wouldn't work on an actual call, even though it works on the test call
The steps listed on page one of that website seems to be ok to try. In order to do this process, you have to make sure that you have already had time machine set up. These are the steps listed:
1. You need Time Machine
2. Go to folder /Library/CoreMediaIO/Plug-Ins/DAL/
3. Copy AppleCamera.plugin to good place (usb memory stick is the best place).
4. Go to Time machine in date that skype work fine.
5. Change AppleCamera.plugin with file from Time Machine
6. Restart system, Now skype need to work with camera.
