Hello all,
thank you for your work on exiftool, it is fantastic!
I have an Azdome GS65H dashcam and I'm looking at extracting GPS information from its videos. From the information below I can see there are gps tracks though the format doesn't seem to be recognized yet.

--------------------------
Out of curiosity I looked at the source code too in ./lib/Image/ExifTool/QuickTimeStream.pl although I couldn't quite figure out out how to decode the data for this camera. I'll be sending a sample video as per https://exiftool.org/forum/index.php?topic=6.0
thank you!
I got the sample, thanks.
ExifTool 12.78 will have the ability to extract GPS from this video.

Amazing, thank you so much for your help!
