            Bug ID: 766588
           Summary: v4l2transform: Does not negotiate anymore [regression]
    Classification: Platform
           Product: GStreamer
           Version: 1.8.2
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: nicolas at ndufresne.ca
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

As of recent change, v4l2 transform was enhanced with scaling support, and
colorimetry support was also added. Though now, it seems those change are
preventing v4l2transform from negotiating. Here's a pipeline that use to work:

  gst-launch-1.0 videotestsrc ! v4l2video0convert ! fakesink

This should be a simple case, as this shall normally be passthrough. Yet, in
current master (and 1.8) it fails with not-negotiated.
