EDIT

Hello I am using Logitech camera by using usb_camera usb_camera.launch file witgh Package brown_ros_usb_pkg for Ros_indigo system.I checked with /devVideo 0 or 1,The Error still there.

<launch>
    <node name="usb_cam" pkg="usb_cam" type="usb_cam_node" output="screen" >
        <param="" name="video_device" value="/dev/video1"/>
    </node>
</launch>

But I get error in Camera Calibration Waiting for service', '//set_camera_info,Service not found.

and now in visualizing the Ar_tags_alvar.I sucessfully build alvar and using ROS_indigo packages.

what camera driver do you start? rviz is just for visualization, it does not start a camera driver...

Please edit your question (click the edit button on the bottom right of your question), don't post additional info as an answer. Is the launch file there correct? The param="" seems to be wrong, but this could also be because you pasted in unformated...
