           Summary: v4l2src negotiation failure with weird
                    pixel-aspect-ratios
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good

proposed patch

The following pipeline fails:

gst-launch-0.10 v4l2src !
video/x-raw-yuv,width=320,height=240,pixel-aspect-ratio=[1/2147483647,
2147483647/1 ]  ! xvimagesink

v4l2src tries to fixate the pixel-aspect-ratio to 1/2147483647, which
xvimagesink is rightfully unhappy with. 

v4l2src doesn't support any non-square pixel-aspect-ratios (or at least
determining this is the case), so it should exposes 1/1 in its caps
