function parse_stream_start():void {
    // Gjs wrapper for gst_event_parse_stream_start()
}

Parse a stream-id event and store the result in the given stream_id location. The string stored in stream_id must not be modified and will remain valid only until event gets freed. Make a copy if you want to modify it or store it for later use.
