I have a Logitech Orbit AF Sphere webcam, and am trying to access it
using the "stopmotion" app. Apparently the stopmotion program calls
vgrabbj to grab an image from the webcam. I am running Ubuntu Desktop
i386 8.10-RC1.

When I run Ekiga, it is able to grab video from the Quickcam perfectly.

When I run the "stopmotion" program, it only imports a green screen.

When I vgrabbg manually, I get a single green picture.

I've read a lot of messages in various forums, but nobody seemed to
have the green picture problem. Since it works in Ekiga, I assume it
should be able to work with stopmotion/vgrabbj.

Any suggestions?
