pi_face_tracker problem
Hi i have installed your package. i am trying to use it ,but i haven't succeeded. firstly i run cheese because without it nothing works. then i run the two commands . from the first one i get a : [ WARN] [1377289686.323464310]: Reconfigure callback failed with exception unable to allocate buffers. the other one works fine . so i get a : [INFO] [WallTime: 1377289898.645841] Starting pi_face_tracker.
the problem is that when i type rostopic echo /whatever gets published then nothing appears on my screen, not even my /camera/image_raw.
the cheese program works fine . what should i do
edit: i just saw the with my laptops camera it works fine. with my msi star cam clip it does not. and when i run the first command i get
