Hi there!
In first thanks to Mr.Harvey. Exiftool worked pretty well for me. My customer became impressed.
But now I have a problem. Can I extract GPS info from a video mp4? I tried unsuccessfully
Thank you for answer.

Try this command
exiftool -G1 -a -s "-GPS*" -ee file.mp4
If this lists a whole bunch of GPS Coordinates, then there's a GPS track embedded in the file. You can extract the data and create a track file, such as a GPX or KML file. See Inverse Geotagging (https://exiftool.org/geotag.html#Inverse).
Exiftool might also extract a single coordinate.
If exiftool doesn't extract a GPS track, then it might be possible that there is one. You would have to share a file to verify if it does.
But any editing of a file will destroy a GPS track. This includes files downloaded from social media or text, as they automatically re-encode any video.
