Hi all.

In ROS2 Foxy I am using v4l2_camera_node to public the topics /image_raw and /camera_info from the camera of my laptop. It seems to works ok, but when I run image_proc I get the following warning:

[WARN] [1614197030.565908600] [RectifyNode]: [image_transport] Topics '/image' and '/camera_info' do not appear to be synchronized.

What can I do to syncronize the topics and avoid the warning?

Thanks in advance.

I had not realized that the topic expected by RectifyNode is different that the one published by the v4l2_camera_node. Once I remap the topic the warning dissapeared.
