Hey everyone

I have not yet been able to retrieve the parameter values of my kinect camera and it is really frustrating since they are essential for my further progress of my project. If I create the following subscriber:

Subscriber para_sub = nh.subscribe("/camera/rgb/camera_info", 1, &processPoint::processInfo, this);

Then no topics are received and if I echo the update rate of the topic, then it cant determine it i.e no topic is present. I am really confused why making topic if nothing is publish on the line, I have also tried using different computers without any result.
