Title: Need help with extracting gpx data from a BlackVue DR970x-2CH
Post by: Kindred on August 30, 2024, 02:15:53 AM
Hello,

I've got videos (*.mp4) from a BlackVue DR970x-2CH. I tried to save the GPS-data in a GPX-file, but it doesn't work.

Output after using command: exiftool.exe -a -ee "-gps*" FILE
GPS Log                         : (Binary data 8264 bytes, use -b option to extract)
GPS Log                         : (Binary data 8264 bytes, use -b option to extract)

Output after using command: exiftool.exe -ee "-gps*" -b FILE > gpsdata.txt
in a attachment file

I tried using the gpslog.config files from the posts:

https://exiftool.org/forum/index.php?topic=12285.0
but it doesn't work.

If you take a look at your gpsdata.txt file you will see that it doesn't contain any valid gps data.  Maybe the gps unit couldn't acquire the satellites?

Note that this data isn't GPX format.  It is basically NMEA with a timestamp prefix.  ExifTool won't convert this to GPX for you.
