Comment (by tvolkert):

 I'll try to attach an mp4 that has location that was taken with my Nexus 6
 phone (file upload just failed, but I'll try again).  My old Moto X
 produced similar mp4s.  ffprobe produces the following:

   Metadata:
     major_brand     : mp42
     minor_version   : 0
     compatible_brands: isommp42

 Note that that appears to *not* be using the "\251xyz" atom, but instead
 the "location" and "location-eng" atoms...

 I also found other code that handles the extraction of the "\251xyz" atom,
 in case that validates its existence... https://code.google.com/p/android-
