Ah, okay.  Gst-inspect-1.0 now shows imxvpu, imxipu, etc.  In order to
decode a simple video from a file, what would the new pipeline look like?
 Normally I would run something like 'gst-launch-0.10 playbin2
uri=file:///myfile video-sink=mfw_v4lsink'.  Can I make a one-to-one
conversion from the old mfw_v4lsink to some other custom element?
