'Formats' are not compatible.
Error 1: cvArr requires the first 4 bytes to determine what data the matrix (or rather a cvMat object) would have. The 1st four bytes contain a rather important datatype information like CV_32FC1, CV_8UC1. Also, OpenCV is rather sensitive to RBG, BGR. Your error is caused since the first 4 bytes are of nothing OpenCV can understand
Error 2: image_view takes image parameter, BUT that is a topic, not a file
So, OpenCV is saying it can't understand whatever you are trying to do, but the actual error lies in the fact that you are subscribed to an empty topic.
