extends GstObject

Padtemplates describe the possible media types a Pad or an ElementFactory can handle. This allows for both inspection of handled types before loading the element plugin as well as identifying pads on elements that are not yet created (request or sometimes pads).

See upstream documentation at https://gstreamer.freedesktop.org/data/doc/gstreamer/stable/gstreamer/html/GstPadTemplate.html

Pad and PadTemplates have Caps attached to it to describe the media type they are capable of dealing with. getCaps() is used to get the caps of a PadTemplate. It is not possible to modify the caps of a PadTemplate after creation.
