Hello,

I am trying to get the  uvc_camera-node (ubuntu 10.10, package ros-diamondback-camera-umd)  to work with my "Philips SPC 900NC PC Camera" usb-webcam, but the node exits with the following error:

pixfmt 0 = 'PWC2' desc = 'Raw Philips Webcam'
  discrete: 640x480:  
pixfmt 1 = 'YU12' desc = '4:2:0, planar, Y-Cb-Cr'
  discrete: 160x120:   1/5 1/10 1/15 1/20 1/25 1/30
  discrete: 320x240:   1/5 1/10 1/15 1/20 1/25 1/30
  discrete: 640x480:   1/5 1/10 1/15
terminate called after throwing an instance of 'std::runtime_error'
  what():  couldn't set format

all processes on machine have died, roslaunch will exit

... shutting down processing monitor complete

I am using the launch-file:

<launch>
<node pkg="uvc_camera" type="camera_node" name="uvc_camera" output="screen">
<param name="device" type="string" value="/dev/video1" />
<param name="width" type="int" value="640" />
<param name="height" type="int" value="480" />
</node>
</launch>

the philips webcam is working with mplayer and the build in laptop camera is working with the uvc_camera-node.

O.Lo
