I am having a similar problem described here and here. The proposed solution is to increase the buf_size argument in the creation of the subscriber. However, I am using roscpp and there is no buf_size argument for NodeHandle::subscribe.
How do I increase buf_size in roscpp so that my subscriber with queue size 1 can always get the most up-to-date data?
On the assumption this is actually an X Y problem: If you are using roscpp, it is probably more appropriate to use the image_transport package when transporting images over your ROS network.
