missing epoch times #12

Hi,

I have a video.mp4 created by my GoPro hero 7 black.

I think that the video's gps/data stream has timestamps, because Racerender v 3.7.3 happily accepts the mp4 file, extracts the data from it, and displays the correct date and local time in edit mode.

However, when I try to extract the data using the command gopro2gpx -s -vvv video.MP4 video the file video.klm just contains lat/lon values - no times.

Is this a bug in gopro2gpx? Or in my use of it?

Hope you can help.

Martin

Hi, you're right, the KML file doesn't contain timestamps, but the GPX file does.

I'm not sure how timestamps in KML files work, from quick searching I couldn't find a way to attach timestamps to single trackpoints, only how a place marker can get a timestamp. I also converted the GPX track to KML using some online tool, and there were also no timestamps in the resulting file.

So I would just use the GPX file
