What is the standard ROS way for implementing on-the-fly resolution changing for a camera node?
I haven't found any official articles on this, also I haven't found any popular camera nodes, supporting this. This feature is critical for my application, I want to implement it for e. g. cv_camera, but what should be the API?
Should it be dynamic_reconfigure parameters? Actually, I have never seen such parameters in a real-live package.
Or should it be some ROS service? set_camera_info, maybe?
Or maybe just standard parameters should be used, so the node should poll them periodically?
