If having trouble with a rosbag-file that havn't been stopped properly, the file will often have an .active extension, telling that the file needs to be reindexed.
To fix this, do the following:
- Install rosbag:
sudo apt install python3-rosbag - Run follwing command:
rosbag reindex brokenfile.bag.active
The new file will have the same name as the previous file e.g., (brokenfile.bag.active). Just remove the .active and use it as an ordinary .bag file
