Hi, Yes, i have already checked with "All topics", the result I have run roslaunch uvc_camera stereo_node.launch then, rosrun stereo_image_proc stereo_image_proc __name:=proc stereo_proc and uvc_camera are working independently. They are only connected to rosout. Am i missing something by any chance? -Abhy -- View this message in context: http://ros-users.122217.n3.nabble.com/uvc-camera-and-stereo-proc-tp2451433p2456745.html Sent from the ROS-Users mailing list archive at Nabble.com.
