Pad.queryDefault

bool queryDefault(gst.object.ObjectWrap parent, gst.query.Query query)

Invokes the default query handler for the given pad. The query is sent to all pads internally linked to pad. Note that if there are many possible sink pads that are internally linked to pad, only one will be sent the query. Multi-sinkpad elements should implement custom query handlers.

Parameters

`parent`	the parent of pad or null
`query`	the #GstQuery to handle.

Returns

true if the query was performed successfully.
