How to find out who published a message (node name), especially for the topic tf, where many nodes are publishing different transforms.
By using the MessageEvent callback signature you can use the getPublisher()
function to retrieve the publisher name (in roscpp). The same appears to be possible in rospy by using Connection Information.
If you play back bags, rosbag effectively is the publisher. I think the connection header approach will therefore not work with rosbag. I'm not sure there is a way to recover the publisher id when playing back bagfiles (I guess not).
