Gst.Element.prototype.query

function query(query:Gst.Query):Boolean {
    // Gjs wrapper for gst_element_query()
}

Performs a query on the given element.

For elements that don't implement a query handler, this function forwards the query to a random srcpad or to the peer of a random linked sinkpad of this element.

Please note that some queries might need a running pipeline to work.
