Hello, I've a number of dashcams (Viofo a129 pro) and I've specified an ID in every dashcam, in 'custom text' and 'car number' in the dashcam settings.
Now I'm trying to read these IDs through EXIFtool.
Here is an example where the value is '0XW'

Phil will have to look closer but my cursory glance using the -v3 (-verbose3) option (https://exiftool.org/exiftool_pod.html#v-NUM--verbose), the -ee (-extractEmbedded) option (https://exiftool.org/exiftool_pod.html#ee--extractEmbedded), and the -u (unknown) option (https://exiftool.org/exiftool_pod.html#u--unknown) doesn't find any value of "0XW".
Data that is burned directly into the video stream isn't always embedded in the file.
The string "0XW" matches a number of random byte combinations in this file. If the string were more unique a binary grep of the file would tell you if it was in there, but I don't think it is.
However, this is yet another format for the timed GPS, and I'll see if I can extract this in the next release.

Edit: This isn't a new format. The GPS isn't extracted because the satellite fix is invalid (recorded indoors?)
Yes ..
I'll upload a new sample with gps data and more unique name.
Truly appreciate the amazing Exiftool and the work you put into it
