When I run the publisher everything seems to work: rostopic echo /camera returns a matrix and rostopic hz /camera proves that something is being published frequently But then, when I want to use the subscriber which aims to display what is sent to /camera I only have a window(with my wallpaper on it) and then it crashes. I saw I was not the only one with this issue but couldn't find a solution. So please if you have any idea how to help me it could be great. :) |
