Pulls a buffer from the peer pad or fills up a provided buffer. Read more

Dispatches a query to a pad. The query should have been allocated by the caller via one of the type-specific allocation functions. The element that the pad belongs to is responsible for filling the query with an appropriate response, which should then be parsed with a type-specific query parsing function. Read more

Performs query() on the peer of self. Read more

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