Attached is a patch that seems to work for desired_encoding = 'passthrough'. Also, from the opencv python cookbok there should be a cv.fromarray to go from cvMat to numpy array. I don't see this in the vision_opencv-1.0.3. What version of the vision_opencv stack does the online documentation correspond to?
