Can rosbag filter handle `tf2_msgs/TFMessage` #1038

Open artivis opened 7 years ago

artivis commented 7 years ago

rosbag filter crashes while filtering over a rosbag that as a tf2_msgs/TFMessage message, independently from the predicate for that matter :

rosbag filter my_bag_with_tf2.bag out.bag "True".

Please provide more information: what exact versions are you using? What is your environment which doesn't seem to include geometry_msgs? Please provide the exact steps to reproduce the problem (including e.g. the bag files used of necessary).

I have the same problem with "unknown package [geometry_msgs] on search path". It appears rospy is buggy in this regard.

@themightyoarfish A "me too" comment isn't going to help for this issue. Please provide the additional information asked for.

It later turned out that it appears the bagfile was the problem since with another one containing the same message types there was no problem. Still it is strange because the bag could be played back with no problem.
