ov5640 camera not detected

[h-sharifzadeh]

Hi
we have a ov5640 camera and we want to use it on a banana pi m64 board.
qtcam can always show capture using a usb camera we connected to our board but it doesen't recognize the ov5640 and it shows the name wrong and error "resource is busy".
we used another app (guvcview) to capture frame and it recognized the camera without any problem but for some reasons we can't use that app.
could you please tell us how to define the camera for your application?
