Can orin nx use the same camera model at the same time?

[1031150349]

I connected two imx219 cameras to the orin nx developer kit. After configuring jetson io, I used the

nvgstcapture-1.0 --cap-dev-node=0 
nvgstcapture-1.0 --cap-dev-node=1

command to output images in the terminal. I found that I could not display the images of two cameras at the same time. When one is displayed, the other will be black.

The phenomenon is:

1. Connect the camera to CAM0 or CAM1, and each camera is available
2. Connect the camera to CAM0 and CAM1 respectively, and input nvgstcapture-1.0 --cap-dev-node=1 to only output the image of CAM0
   Does orin nx support the simultaneous display of two images by default? I also have the same problem when using v4l2-ctl to obtain the stream.
   The system I use is jetpack5.1.2 flashed by sdk manager. If you have 2 cameras, can you help test it? Thank you very much.

Use --sensor-id=0/1 instead of --cap-dev-node for CSI camera.

Thanks

Thank you very much, it solved my problem. By the way, does --cap-dev-node only support v4l2 cameras?

Use for USB camera.

If I want to get the image of the CSI camera, which document should I refer to for development.
