2015-09-08 04:39:53 -0500 asked a question Why do I get this error "terminate called after throwing an instance of 'std::runtime_error' what(): pixel format unavailable" ?

I am trying to run ar_sys on ROS Hydro with a Logitech USB Camera. However on running the command

roslaunch ar_sys single_board.launch

it gives me an error:

terminate called after throwing an instance of 'std::runtime_error'   what():  pixel format unavailable.

I want to connect my kinect such that I am able to detect the Aruco markers from the Kinect images. Right now the Ros_Aruco package doesn't detect the kinect RGB camera.
