            Bug ID: 747557
           Summary: zbar: Get an image along with the barcode
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: gnome-bugs at muelli.cryptobitch.de
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

I am using the zbar element and I would like to "catch" the image that
made zbar decode a barcode.
So I do not only want to get the decoded barcode, but also the image
which caused zbar to generate a signal.

The scenario is that an attacker could "inject", for a frame or two, a
malicious image. And I want to show the user "see, this image apparently
contained a barcode which decoded to this string".
