Warning message using the Geolocate feature on some MP4 files

[FrankB]

@Moderators: Not sure if this topic belongs here, or in the ExifToolGui section. Feel free to move if it belongs there.

@Phil.

In ExifToolGui I'm using this command to geolocate files.
-XMP-photoshop:XMP-iptcCore:XMP-iptcExt:geolocate<GPSPosition -api geolocation <list of files>

For some MP4 files I get a warning 'No such city in Geolocation database'. What is wrong with it I dont know, but the message makes no sense to me. If I use the same function, with the same coordinates on a JPG it works fine.

Note: The version V6.3.0. that I released yesterday uses the command you proposed earlier:
-geolocate<GPSPosition -api geolocation -xmp:LocationShownCountryCode<GeolocationCountryCode -xmp:LocationShownCountryName<GeolocationCountry -xmp:LocationShownProvinceState<GeolocationRegion -xmp:LocationShownCity<GeolocationCity <list of files>
But the results are the same.

I have compared an MP4 file that gives the warning, with an MP4 that gives no warning. This might be a clue.

Additional info:
Also if you're not updating the files, but use this command:
-api geolocation -geolocation* <list of files>
the same warning appears for the MP4 file, not for the JPG

Privacy note: This is not my home location, just an hotel where I once stayed.

Altitude seems to confuse Geolocation in movies:

I can confirm that the Altitude makes a difference. Very good catch!

[Phil Harvey]

Thanks.  I'll fix this.  Edit: this was already fixed in my current working version.

But Frank, your command:

-XMP-photoshop:XMP-iptcCore:XMP-iptcExt:geolocate<GPSPosition -api geolocation <list of files>

Should not be using the API Geolocation option.  That option is only used to generate the GeolocationXxx tags, which you are not using here.

Thanks Phil,

- For looking into the warning message
- For pointing out the needless use of '-api geolocation'. Even worse without it the warning would not have appeared.

Will fix it in GUI.

Hi Frank,

12.80 is now available.

Hi Phil,

Works as expected. Thanks.

P.S.: GeoLocation is a hot topic, looking at the nr of posts lately. You opened a can!
