How to get GPIO Output on Jetson Nano with DeepStream for Object Detection

Accelerated Computing Intelligent Video Analytics DeepStream SDK

I’m working on a project with the Jetson Nano and DeepStream, where I need to trigger a GPIO output when an object is detected. Could someone please guide me on how to implement this functionality?

Specifically, I’m looking for details on:

  1. How to integrate GPIO control into the DeepStream pipeline.
  2. Any example code or resources that demonstrate this process.

DeepStream is a SDK. Normally GPIO trigger should be done through driver level software.

DeepStream can output detected objects. And there are lots of sample apps to demonstrate how to get detected objects in the pad probe function, E.G. /opt/nvidia/deepstream/deepstream/sources/apps/sample_apps/deepstream-test1.

There is no limitation for how to use the detection result from DeepStream side.
