So was looking in the GStreamer API how to get a thumbnail image. I understand I might depend on a file format, but is it any way to get that picture ? I found in the Internet something called "preview" or "preview-image" tags that I can retrieve, but again I didn't find how in the API.

you can use the "frame" property on playbin2 (in conjuction with "convert-frame"
action signal). If you want to use decode bin directly look at
gst-plugins-base/gst/playback/gstscreenshot.c
for what this is doing and refit it to your app.
