The dashcam I have is this: https://in.redtigercam.com/products/redtiger-f9-4k-dual-mini-dash-cam
I ran ffprobe on the video file and got the name "ShenShu MetaData" which led me to this forum post: https://exiftool.org/forum/index.php?topic=15881.0 (https://exiftool.org/forum/index.php?topic=15881.0)

I then ran `exiftool -G1 -a -s -GPS* -ee3 input.MP4` on the file and got just this output:
Warning: [minor] LigoGPS trailer at offset 0x9ffe0ec (7956 bytes) - input.MP4
The video has GPS data I believe because the dashcam app is able to show the data as an overlay.
The video file is in this folder:

My hunch is that this "ShenShu" is the same as https://exiftool.org/forum/index.php?topic=15881.0 but the format has changed? Anyone know what's happening here? Thanks in advance!
It will be a couple of days before I'm back on a fast internet connection and able to download the file, but I'll take a look at it then.
- Phil
You're right. The format is very similar to the Wolfbox, but the header has changed and the scaling factors are different. It also contains a duplicate set of GPS in the form of a non-encrypted LigoGPS trailer.
ExifTool 13.31 will read both of these. You may read them separately by specifying either the Track3 or Ligo group.

Thank you so much!
