It's nothing more than

  gst-launch-1.0 -v v4l2src ! <any needed conversions> ! xvimagesink

in my case, the conversions are bayer2rgbneon.  However, this only shows
you the frame rate negotiated on the pads (which is actually good enough
to show the issue.)

How I stumbled across though this was when I was trying to encode:

 gst-launch-1.0 v4l2src device=/dev/video9 ! bayer2rgbneon ! \
	videoconvert ! x264enc speed-preset=1 ! avimux ! \
	filesink location=test.avi

I noticed that vlc would always say it was playing the resulting AVI
at 30fps.
