Hi,
You can try to set up RTSP server on the Jetson Nano with raspberry pi camera. Please refer to
Q: Is there any example of running RTSP streaming?
Please try with videotestsrc plugin first to make sure it works. And then you can try the command like:
$ ./test-launch "nvarguscamerasrc ! nvvidconv ! nvv4l2h264enc ! h264parse ! rtph264pay name=pay0 pt=96"
On the other Jetson Nano, you can run DeepStream SDK to receive/decode RTSP stream and do inferencing. Please refer to the document(6.0.1):
