Hello, I don't have ekiga right here but I am pretty sure the greenish image with some wite lines or spots is a YUV (or black lines or spots) is an YUV format encoded video blitted in a RGB surface. Look if ekiga is linked against SDL - I think that would be a good start. I didn't used ekiga till now but I am somehow working with video capture application developpement. Also look at si command line arguments and see if it says something about the video part. Many of the recent years USB cameras do not stream RGB (just YUV and Ixx) formats. For checking for SDL linked to ekiga do an ldd ekiga and check in the list.
I might also be on the wrong path - however the greenish image is very typical for YUV-RGB blitting.
