/**
 * GhostPads are useful when organizing pipelines with GstBin like elements.
 * The idea here is to create hierarchical element graphs. The bin element
 * contains a sub-graph. Now one would like to treat the bin-element like any
 * other GstElement. This is where GhostPads come into play. A GhostPad acts as
 * a proxy for another pad. Thus the bin can have sink and source ghost-pads
 * that are associated with sink and source pads of the child elements.
 *
 * If the target pad is known at creation time, gst_ghost_pad_new() is the
 * function to use to get a ghost-pad. Otherwise one can use gst_ghost_pad_new_no_target()
 * to create the ghost-pad and use gst_ghost_pad_set_target() to establish the
 * association later on.
 *
 * Note that GhostPads add overhead to the data processing of a pipeline.
