I am using ROS hydro Ubuntu 12.04 and I'm having an error when running"ffmpeg -r <FPS> -b <BITRATE> -i frame%04d.jpg <OUTPUT>.avi" The thing is I am not seeing the sequence of images.I ran rosbag info <BAGFILE> to obtain the topic in the bag file but when I run "rosrun rqtgraph rqtgraph" the /extract_image frame node is there all by itself.It's getting messy.What am I doing wrong?
