Cannot make it work withKinect v2 

Hello,
I wrote a code that parses the rgb stream from the kinectv2 and i'm trying to recognize the tags but it does not work.
I also tried to resize the frame to 640x480 but nothing changed.
i'm not passing any parameter to the command line.
I think the detector is running normally because sometimes it recognizes something random.
Do you have an idea of what it might be the problem?
Thanks
