libunicap - the imaging source - frame rate

hello,

I'm trying to use libunicap release 0.9.8 to take images with the camera " the imaging source AUC/BUC CMOS".

I absolutely need to take 60 frames per second with this camera but I had issues while trying to change the frame rate of the camera: the default frame rate is 30 fps and I didn't manage to change it.

In the graphical interface, the " box" permitting to choose the frame rate doesn't propose another frame rate than 30 fps.

Is it possible to use the 60 fps capabilities of the camera using the libunicap libraries?
and how can I manage to change the frame rate of the camera?

thanks a lot for your help.
