It's a known bug. Ekiga doesn't resize all supported format (RGB, YUV420P,
YUYV, UYVY, ...) but crop someone (YUYV, UYVY, ...). So you don't have the
full image but a part of the image (just center you face in the top left of
the image). Sometime, the crop is done by the driver (like the spca5xx). I
think in the old gnomemeeting you have the already this "feature". It's very
long to write good resizing code, because you need to test it with some
material (picture from the webcam), and don't try to takes a lot of times to
do the job. Else we can convert all image into YUV420P, and resize the
YUV420P but it's not efficient (memory & cpu).

I'll implement some resizing capability but i'm not sure that your webcam
will be supported in the next batch.
