The encoding appears to be OK (rgb8). 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.
