Assume an OMAP DSP with gst-openmax.  A GPP running Linux uses v4l as a 
gstreamer src and needs to send buffers to the OMAP DSP to be encoded 
which then sends buffers back to the GPP for transmission over 
ethernet.  There needs to be a gstreamer proxy (marshalling) that 
connects the GPP GStreamer Bin to the OMAP DSP GStreamer Bin.
