In `ArenaCameraNode::setupRectification` method `cv_bridge_img_rect_->encoding` is given the value of `img_raw_msg_.encoding` but at that time the raw msg encoding value is empty since in `ArenaCameraNode::startGrabbing` it is given value ( `img_raw_msg_.encoding = currentROSEncoding();` ) after `ArenaCameraNode::setupRectification` runs so the resulting encoding in `cv_bridge_img_rect_` is empty and the `/arena_camera_node/image_rect` topic is broadcasted with empty `encoding` in the messages. Getting the encoding of the rectified images by calling `currentROSEncoding` fixes the problem.
