I'm getting the following error when using roslaunch orb_slam3_ros_wrapper euroc_mono.launch

[ WARN] [1670076780.160426745]: TF_OLD_DATA ignoring data from the past (Possible reasons are listed at http://wiki.ros.org/tf/Errors%20explained) for frame camera at time 0.000000 according to authority unknown_publisher

RVIZ shows up and I can see my video feed. I'm also able to see the SLAM working for just one frame before the ORB-SLAM crashes and RVIZ is left behind.

The log seems not be available...

Hi @MagnusErler , it seems the error is on OpenCV's side instead of the wrapper. Maybe you can check this out https://stackoverflow.com/a/33819978

I also have the same issue. i checked out you link and looked for cv.VideoCapture(0) line in all files with grep, found nothing meaningful. Do you have any other ideas?
