Is there a topic, actionlib, or service interface for controlling the recording of bag files?

Related really old post: http://lists.ros.org/lurker/message/2... (was http://ros-users.122217.n3.nabble.com...)

I was wondering if there is a way to make rosbag expose a service to pause/resume the recording? This would be quite useful in a data-collection application we are currently building, where we don't need to record all the time, but only on certain segments of the trajectory.

Any thought on this functionality?

Thanks

Hi Cedric,

Yes, that functionality is on our roadmap. Until then, you could look to rosbag/recorder.cpp and rxbag/recorder.py for implementations of bag recorders. It should be straightforward to add service-based pausing/resuming on top of those.

Fyi, notes on planned future ROS functionality are kept here: http://www.ros.org/wiki/ROS/Roadmap. It's great to get feedback from the community about what features would be useful, though.

Thanks, Tim
