QCameraInfo not recognising multiple cameras from frame grabber

I have developed an application to show the camera output. Cameras are connected using the frame grabber card (PCIe with two channels). The strange part is that I can only see one device output. Moreover the QCameraInfo is also detecting just one device. Also out of two ports only one port provides the detection in QCameraInfo class.

Can anyone suggest me the possible reason. Or is there a way to select different channel using the Qt Class?
