In my limited test case with about ten mp3 files having embedded 
artwork, the Info-property always provided the mimetypes "image/png" 
resp. "image/jpeg" as first key. Further keys like width, height or 
sof-marker were always contained in a further collection.

However, in the hard-to-understand GStreamer documentation 
"https://gstreamer.freedesktop.org/documentation/tag/gsttag.html?gi-language=c"; 
under "gst_tag_image_data_to_image_sample" I found, that the actual data 
may consist of an URI to the image rather than the image itself. So the 
key could be (quote) "image/jpeg, image/png, text/uri-list".

According to my interpretation this documentation confirms that the 
first key always provides the mimetype, but I wouldn't bet on it.

What version of Gambas is going to get the new MediaSample class?
