There is already a post for GPS from mp4 videos:
https://github.com/drewnoakes/metadata-extractor/issues/127
No mention about any other video formats though.

I’ll look at that tonight, maybe if no gps data set the clipboard to ‘No GPS’ instead of leaving it unchanged.
What do you mean by ‘Automatic mode’?
You can’t call the tool from within a skin, the jAlbum user has to select a video within a project and then run the tool. If a skin makes use of jAlbum variables for gps then the skin will use the extracted gps data.

If you want to incorporate the tool in to a skin then the code from the tool would need to go in init.bsh and be modified to process all videos. You can see how to do that with my images to video tool, but it is not something I want to do.

It's not particularly clean to have to rely on an external executable for this. Better to have the Metadata-extractor library updated to handle this.

Because it uses exiftool under the hood which adds complexity and dependencies I wish to avoid. We have enough support cases anyway.

Rob, I don't understand what you mean:

I use your tool for all the videos in the album, with as result that some user variables are added, see enclosed screenshot.
But you see too that the location window does not show the location.
Next I make the album and retrieve the GPS coordinates with code like this:

var gMap = [<ja:fileiterator start="0" >
 <ja:if exists="gpsLatitude">
  <%
  loc= getLocation();
  %>
'${loc}',
 </ja:if>
 <ja:else>'',</ja:else></ja:fileiterator>
];

and see that the gMap enties for videos are still empty. So it does not work.

Edit:

It works if I change the code into:

var gMap = [<ja:fileiterator start="0" >
'${gpsLocation}',
</ja:fileiterator>
];

See this video test album.

The video creation date is made with this code:

   bv= meta.get("Date/Time Original"); 
   if ((bv == void)||(bv == null))  bv= meta.get("Quicktime video.Creation Time");
   if ((bv == void)||(bv == null))  bv= meta.get("Mp4 video.Creation Time");
   if ((bv != void)&&(bv != null) && bv.startsWith("Fri Jan 01 00:00:00")) bv= meta.get("File.File Modified Date");
   if ((bv != void)&&(bv != null))  {
     DT= getText("expDate") + ": " + bv +", "; 
   }

Thanks for your help!

For the creation code I use now this code:

  bv= meta.get("Date/Time Original");
  if ((bv == void)||(bv == null)) {  /* Video? */
	bv= meta.get("Quicktime video.Creation Time");
	if ((bv == void)||(bv == null))  bv= meta.get("Mp4 video.Creation Time");
	if ((bv != void)&&(bv != null) && bv.startsWith("Fri Jan 01 00:00:00")) bv= meta.get("File.File Modified Date"); 
  }
  if ((bv != void)&&(bv != null))  {
     DT= getText("expDate") + ": " + bv +", "; 
   }

But this is still not correct because the 2nd video in this album reports as creation date 'Sun Sept 11', but the meta data contains these lines:

Quicktime sound.Creation Time=Mon May 06 10:41:09 CEST 2013, 
Quicktime video.Creation Time=Sun Sep 11 07:44:02 CEST 2011, 

So the sound is created 5 days earlier on 'Mon May 06 '!!

To solve this I changed the code into:

  bv= meta.get("Date/Time Original");
  if ((bv == void)||(bv == null)) {  /* Video? */
  	bv= meta.get("Quicktime.Creation Time");
	if ((bv == void)||(bv == null))  bv= meta.get("Quicktime video.Creation Time");
	if ((bv == void)||(bv == null))  bv= meta.get("Mp4 video.Creation Time");
	if ((bv != void)&&(bv != null) && bv.startsWith("Fri Jan 01 00:00:00")) bv= meta.get("File.File Modified Date"); 
  }
  if ((bv != void)&&(bv != null))  {
     DT= getText("expDate") + ": " + bv +", "; 
   }

Yes indeed, the difference is larger.

But something strange is going on:

The 2nd image IMG_0205.mp4 shows:

Quicktime sound.Creation Time=Mon May 06 10:41:09 CEST 2013, 
Quicktime video.Creation Time=Sun Sep 11 07:44:02 CEST 2011, 
Quicktime.Creation Time=Sun Sep 11 07:44:02 +02:00 2011,

But the preceding image IMG_0877.mp4 shows the same date:

Quicktime.Creation Time=Mon May 06 10:41:09 +02:00 2013, 
Quicktime sound.Modification Time=Mon May 06 10:41:21 CEST 2013,

So I wonder goes something wrong with fetching the meta data?
