Revision history [back]

The rsobag wiki page does not document any options related to snapshotting, and from reading through the roabag source code I don't see any way to set the snapshot option you're referring to from the command line.

If you're feeling adventurous, you could try to write your own wrapper program for the rosbag Recorder object which sets the snapshot option; then it should listen on the snapshot_trigger topic and take a snapshot whenever a message is published on that topic.
