How to use multiple depth sensors with OpenNI/OpenCV ?

I'm using OpenCV 2.4.4 built from source with OpenNI support and I'd like to use two Asus sensors at the same time. Is that possible with OpenCV ? If so how ?

If I initialize a sensor like so:

VideoCapture sensor1;sensor1.open(CV_CAP_OPENNI_ASUS);

How can I init the second ?

did you try : VideoCapture sensor2;sensor2.open(CV_CAP_OPENNI_ASUS+1); ?

@berak Just did and it works ! If you want to add that as an answer I'd be more than happy to accept. Thanks!

this will work:

VideoCapture sensor1;
sensor1.open( CV_CAP_OPENNI_ASUS );

VideoCapture sensor2;
sensor2.open( CV_CAP_OPENNI_ASUS + 1 );
