Front camera using ofiPhoneVideoGrabber?

Is it possible to pick front or back camera with ofiPhoneVideoGrabber?

ListDevices() outputs nothing and setDeviceID doesn’t seem to do anything either.

I noticed it was possible taking photos in ofxiPhoneImagePicker to use openCamera(int camera=0);

Is it only possible through:
