I believe the short answer is "no." There's no standard for storing GPS coordinates in a MP4 file, to say nothing of all the other video formats out there, so jAlbum doesn't really have a way of extracting them. I thought perhaps one could enter coordinates manually, using the Location panel in editing mode, but information entered there seems to vanish.
Might make for a good feature request. If GPS coordinates are entered manually, they could be stored in the .jalbum/whatever.mp4.info file, and the core could return them whenever a skin asked for the GPS coordinates for that object.
The problem is event though jAlbum allows you to add location to Media files it forgets it right away. Perhaps the xmp library can't handle media files. Still jAlbum could utilize the slide variables to store it as you suggested above. Maybe David could come up with a solution.
It is a solution for those who are willing to accept a functional alternative....
How is it functional? As I said, it produces a map marker that does not take the visitor to the video. That's clearly non-functional.
Different visitors come up with different feedback:
Hallo Karl, heute [5. November] taugt das Wetter um die vielen Fotos anzuschauen, die Du von Marokko geschossen hast. Eine große Vielfalt, die alle Facetten der Tour zeigt. Geordnet und beschriftet - so macht es Freude einen Rückblick zu starten und ablaufen zu lassen. Diese vielen Eindrücke habe ich gar nicht aufs Foto bannen können. Vielen Dank für Deine Mühe!
In my album, video is not showing location in google map, only for photos...
Is it possible to show where video is starting or something similar in google map?
Thanks in advance...

Another not implemented feature request, see here.
Add the generated GoogleMap,html or map.kml file to a button for a Google Maps link.
Now delete the poster image, include the corresponding video again and make and upload the album.
To see an example of such an album made with the PhotoSwipe skin click here and next click the left Google Maps button and finally on the ‘Kerkplein’ marker on the left side of the map.
Click on the image to open the corresponding slide page and start the video.
