I've so far been unable to extract data from the MP4 files written by this dashcam.
exiftool -a -ExtractEmbedded -G1 -s <filename> doesn't reveal any GPS data.
sample MP4 file available here:
https://drive.google.com/file/d/17r2mRKJershQwIrM1QQ5HL8bKWjixT8L
If it helps, the dashcam writes the MP4's into the directory "/Novatek/Movie/"
operating environment:
12th Gen Intel(R) Core(TM) i9-12900K 3.19 GHz, 32.0 GB
Windows 10 Pro, 22H2, Windows Feature Experience Pack 1000.19041.1000.0
cygwin, exiftool 12.63 (windows executable)
I got the sample. I'll take a look at it when I get a chance and post back here then.

This looks to be the same format as in this post (https://exiftool.org/forum/index.php?msg=71743), except it has an extra 32 bytes in the header. Unfortunately I haven't yet been able to decode this format.

Thanks Phil. This is the Rexing player that can decode the gps info from the mp4's:

The player unfortunately does not have the ability to export gps data in kmz or other formats (I have a request into them to update the player for that capability)
