Simple Tutorial is Not Working

[dokodoko123]

I am currently trying to run the Simple Tutorial of stella_vslam using SocketViewer. I am following this documentation, but it is not working correctly. Specifically, when I use this command (./run_video_slam -v ./orb_vocab.fbow -m ./aist_living_lab_1/video.mp4 -c ~/lib/stella_vslam/example/aist/equirectangular.yaml --frame-skip 3 --no-sleep --map-db-out map.msg), I get the following output.

I am not sure what the issue is, so if anyone can help me understand the cause, I would greatly appreciate it.

If --no-sleep is set without --start-timestamp, timestamps may overlap between multiple runs.
