Deepstream pipeline for 1 to 3 cameras

Question

Anyone knows how to create a deepstream pipeline by using deepstrea-test1 from the API Example and run inference on Jetson Orin? I get single camera to work and multple video stream, but not the three camera.

I can add code if anyone needs it, else the nVidia code:

And for single camera:
