When processing a GoPro video using mapillary_tools v0.14.4 the tool raises unjustified MapillaryCaptureSpeedTooFastErrors:

Thanks for reporting. This should be a known issue for Timelapse videos. See https://forum.mapillary.com/t/mapillary-tools-mapillary-capture-speed-too-fast-error-when-capturing-at-freeway-speeds-via-gopro-timewarp/9785

To mitigate, run the command with envvar MAPILLARY_TOOLS_MAX_CAPTURE_SPEED_KMH=inf set to disable the speed check. Let me know if it works.

How can I set this envvar / how does a mapillary_tools command looks like then?

Hi @ptpt ,
under Win11: I can confirm that the issue is fixed when I create an environment variable MAPILLARY_TOOLS_MAX_CAPTURE_SPEED_KMH
and set it to inf. As a workaround this is fine for me.
My ask would be that mapillary_tools processes videos consistently when it comes out of the box.
