# GstGhostPad

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.
