The problem seems to be that neither DC1394 driver is publishing the sensor_msgs/CameraInfo topic. I was confusing that with the sensor_msgs/SetCameraInfo service request (also missing at present). It seems that rviz *does* depend on CameraInfo. That should be simple to add to the drivers. SetCameraInfo may be more difficult. I don't know enough about the code yet to say. -- joq
