Hi,
I recently bought an Odroid XU4 and installed the latest Ubuntu mate16.04. I managed to successfully install and compile OF 0.9.8 linux armv7. The problem now is that in an app I use the ofVideoGraber to get the frames of a usb webcamera. Here is the code:
cam.listDevices();
cam.setDesiredFrameRate(30);
cam.initGrabber(640,380);
This code works on windows and on other Ubuntu machines but not on Odroid XU4 because I get this error:

When I list the video devices (using list -l /dev/video*) I get video0 (the web camera), video6 and video7.
Do you have any idea how to solve this?
Thanks,
