gnomemeeting w/veo stingray


I've been trying to get gnomemeeting to work with my veo stingray webcam. The camera is function and works fine using camstream. Gnomemeeting whines about the frame size however. It is looking for either 352x288 or 176x144, and my camera produces 352x240. Is there something I can pass to modprobe imbcam that will fix this? Here's the result of dmesg | grep usb

From the kernel docs (ibmcam.txt)

size This setting chooses one of several image sizes that are
supported by this driver. Cameras may support more, but
it's difficult to reverse-engineer all formats.
Following video sizes are supported:

size=0 128x96 (Model 1 only)
size=1 160x120
size=2 176x144
size=3 320x240 (Model 2 only)
size=4 352x240 (Model 2 only)
size=5 352x288
size=6 640x480 (Model 3 only)

The 352x288 is the native size of the Model 1 sensor
array, so it's the best resolution the camera can
yield. The best resolution of Model 2 is 176x144, and
larger images are produced by stretching the bitmap.
Model 3 has sensor with 640x480 grid, and it works too,
but the frame rate will be exceptionally low (1-2 FPS);
it may be still OK for some applications, like security.
Choose the image size you need. The smaller image can
support faster frame rate. Default is 352x288.

Hey thanks for the quick reply. I had already tied that, but it only changes the videosize and not the canvas. Gnomemeeting still whines. I added /sbin/modprobe ibmcam size=2 to rc.modules. Here's the result of dmesg | grep usb
