Ottela is the best person to speak to here, but I would add that 
extractor support for helix has to be compile time enabled 
(--enable-gstreamer-helix). I don't think this is the case by default.

You also need the right GStreamer packages installed IIRC. According to 
this page:

  http://gstreamer.freedesktop.org/documentation/plugins.html

That means you need gst-plugins-ugly packages installed.

Hope this helps,
