rosbag play [bag path] results in [FATAL] Error reading version line

[Huxwell]

In what format should I pass files to rosbag play?

I have tried:

• .zip
• .db3
• .db3-wal
• .db3-shm
• path to dir
• the metadata.yaml

The files above were generated using Livox LIDAR. Do you have any example file for which the repo should lunch OK?

I was able to covert folder with the files above to .bag using this library: https://gitlab.com/ternaris/rosbags rosbag-convert path_to_dir

rosbag info of resulting file:

the rviz -d rviz.rviz visualization seems empty with .bag resulting from such a conversion

How should it look like? Can you provide an example?

[Huxwell]

I have tried using your https://www.livoxtech.com/simu-dataset simu_data.bag dataset, but then I will get no detections - only 'Subscribed' print. Nothing in rviz as well

This video seems to point to a good starting .bag (from kitti dataset) -> https://www.youtube.com/watch?v=e0r4uKK1zkk&ab_channel=SanketGujar
