A class that represents pseudo link pads.
Gst::GhostPad are useful when organizing pipelines with Gst::Bin 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 another Gst::Element. This is where Gst::GhostPad come into play. A Gst::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, create() with a Gst::Pad argument is the method to use to get a ghost-pad. Otherwise one can use create() with a Gst::PadDirection argument to create the ghost-pad and use set_target() to establish the association later on.
Note that Gst::GhostPad add overhead to the data processing of a pipeline.
