I use this hack for gst-launch that adds a probe on any pad:
  http://github.com/mrchapp/meta-texasinstruments/blob/for-23.i3.5-pre2/packages/gstreamer/gstreamer/gst-0.10.25-gst-launch-Add-pad-probe.patch

Then you can do:
  gst-launch --padprobe videosink0:sink --timer \
    videotestsrc ! fakesink name=videosink0
