rosbag play bagfile.bag
ROS's bag player provides a nice tool to replay the data but it's kind of difficult for debugging as we can't control frame-by-frame play. I know it's possible to control replay speed by the
-r option but is it possible to play it frame-by-frame? e.g in
rqt_bag we can move frame by frame to see the value (although it can't publish the single frame).
How do you debug your program with ros bag file?
