            Bug ID: 766477
           Summary: videoscale: ignores possible passthrough in
                    fixate_caps
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-base

     GNOME version: ---

While implementing bug 756935, I noticed that videoscale ignores the unfixed
width/height and ends up scaling itself rather than in the sink.

If upstream has fixed caps (e.g. from a video file) and a preferred
width/height in the first structure and unfixed width/height in subsequent
structure/s, then videoscale is truncating before attempting to fixate which
will lose the unfixed caps.
