Title: Unable to extract GPS metadata from a Garmin mp4 video
Post by: lmsh1 on September 26, 2022, 05:42:25 PM
Hello,

I used the following command to extract the GPS metadata from my Garmin DriveAssist 51 video.

exiftool -p gpx.fmt -ee travel_lapse_1.mp4 > out.gpx

Sadly the output is kind of empty:

As sugested I uploaded a short sample video to my googledrive (https://drive.google.com/file/d/1p5u-E9aEeZIGmRuXxqaFeqXdtMW_A-tx/view?usp=sharing).

Thank you in advance!

Thanks for the sample.

ExifTool 12.46 will be able to extract this GPS.  (Thanks makes 60 different formats now.)

I was just looking at a Garmin DriveAssist 50 MP4 file.  It is stupid, but the DriveAssist 50 stores GPS in an entirely different format from the DriveAssist 51.  You would think it could save some effort if they used the same format. :P

The whole streaming GPS metadata thing is a real fiasco.
