           Summary: videoconvert element provides bad pixel-aspect-ratio
                    caps
    Classification: Platform
           Product: GStreamer
           Version: 1.0.3
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good

I've discovered an easily-reproducible case where videoconvert is taking a caps
with a pixel-aspect-ratio of (fraction)[ 1/2147483647, 2147483647/1] and
choosing 1/2147483647 for its (arbitrary) value, rather than something sane
like 1/1

Arguably in this case the source should probably be providing a solid aspect
ratio, rather than a range, but I think that is a separate bug.

The command line that caused this was:

gst-launch-1.0 ximagesrc display-name=":1" ! videoconvert ! xvimagesink
display=":2"

In case this doesn't behave the same for other folks, here's a link to a full
log of an attempted run:
