Discrepancy between video and GPS data

[Trigve]

Hi, I've found your wonderful project and started to test it (using docker). But I think I found a bug.

I've got a GoPro 9 timewarp x10 video. I want to add some overlays to it. The problem is that the longer/bigger the video is the more discrepancy there is between the video and the overlays (speed, map position, ...). For instance if the video is 40 seconds long everything looks ok. But if the video is for instance 3 minutes long, the overlays doesn't match the original video (for instance, overlay is saying that the speed is 16 KPH, but the "video" isn't moving for another 2 seconds). I could send you the testing video if needed.

Hi. Thanks for your interest in the project.

Yes, please can you send me the file.

Please could you send a link to [email protected] wetransfer can be good for this.

I'll just use the file for diagnostic purposes, and it will stored on encrypted drives, and removed when I solve the issue.

Thanks!

So I've tried to prepare video for you, but unfortunately I've accidentally deleted the (testing) video that was causing problem. With the another one, everything is OK. So I would try the other ones I have and will report back if there is same problem.

No worries. Well I guess it is good that it is working some of the time at least. :-)

To be honest the timewarp code is not much used by me, so I can imagine there are edge cases that don't work 100%

In particular, I think switching timewarp settings while a video is recording will not work properly.

If you have a video that shows a problem please do let me know!

Cheers

James
