Accessing metadata and extended metadata of a jpg-photo

Hello,

I'm done some Qt Symbian programming already, but now need to learn more... :)

Special interest at the moment is the use of camera and exif information that
can be included in e.g. jpg-files.

There is a simple wiki example at the forum:
[url]http://wiki.forum.nokia.com/index.php/TSQ001609_-_Using_Qt_Mobility_to_get_metadata_from_media_files[/url]

I have tried this but have had the following problems:
- had to change "QtMediaServices" to "QtMedia" to build without errors,
- when I run the example in a photo-shooting example I implemented for N5800 I get
zero size for both metadata and extended metadata.

Note, that the photo shooting application itself works properly, I get the photo in jpg-file.
If I check the properties of the jpg-file in PC there are lots of metadata.

=> So anybody has any idea of why is it
that I cannot read the metadata and extended metadata?

One thing that is a bit confusing is that both camera (camera = new QCamera(this);) and
imageCapture (imageCapture = new QStillImageCapture(camera);) that I use in my application
are inherited from QMediaObject which has the access functions metaData() and extendedMetaData().
=> So should I access the metadata via the camera-object or via the imageCapture-object?
(I've tried both with the same result: metadata size is zero.)

I'm using Qt 4.6.2 and S60 5th ed. SDK v1.0, QtMobility is 1.0.0-beta1.
(Maybe these are already old versions but they have served me well - at least so far...)

- Thanks everybody for sharing your valuable time for this!

Ooops,
the automatic smile generator make two more than I intended.
There should not be any smily after (this) and (camera).

But the problem still exist :(

have you found a solution?
