Hello,

Is there any way in either python or c++ to access rosbag file data without stopping or closing it as opening a bag file while it is recording data throws a ROSBagUndexedException and corrupts the bag file in most of the cases.

Afaik: no, this is not possible.

The (final) index is written upon closure, and reading a bag files requires the indices to be present.
