I'm trying to implement the uvc_camera stack on a beaglebone to be able to have the beaglebone drive the camera capture, however I am getting errors during startup, and the process is dying. The current error is:

I had to install the armhf v4l-utils and its dependencies to get it this far.

The code has been compiled from source and the same code runs reasonably well (ie I get an image) on my x86 machine.

I am wondering if there is something I may be missing in my ubuntu configuration on the beaglebone, or something else.

Any suggestions will be appreciated
