Read accelerometer data if no GPS data

[Meypqr]

I need the accelerometer data from my Azdome GS63H, to try some stabilizing. The camera is already supported (see QuickTimeStream.pl line 1424), but my problem is as follows:
I normally do not have GPS data, so "return 0" in line 1458 kicks in, as there are only zeros and no [NS] or [EW].

.\exiftool -ee -V3 video.MP4

So no GPS data is saved (OK), but also no accelerometer data is read (line 1468) (not OK).
The data is present, as I can view it in the Azdome application.

It would be great if this could be fixed. Thank you.

I will look into this if you can send me a sample for testing (philharvey66 at gmail.com)

As I had to upload the file to Google Drive anyways, I just share it here:
short video with lots of movement

I also added a shcreenshot of the Azdome application.

I got your file, thanks.

ExifTool 12.61 (to be released within a few days) will extract timed GPSDateTime (presumably generated from the internal clock), and Accelerometer from this video with the -ee option.

Great news, thank you!
