Hi,<br><br>Does anyone have any experience with viewing a image stream from a usb webcam?<br><br>I have the usb_cam node (part of the bosch_drivers package) running, but I can&#39;t seem to view the video in rviz.  It gives me an error saying &#39;fixed frame does not exist&#39;.  I get the same error when I run the camera using the uvc_camera node as well.<br>

<br>With both nodes, I can see that the camera is turned on (the led next to the lens lights up), and I can display the raw image dump i a terminal, but what is the best way to actually view the video?<br><br>Thanks.<br>
