Example Graph for Jetson Nano Orin CSI camera?

Accelerated Computing Intelligent Video Analytics DeepStream SDK
1

• Hardware Platform (Jetson / GPU)
Jetson Orin Nano 8GB Dev Kit

• DeepStream Version
7.0

• JetPack Version (valid for Jetson only)
6.0

• TensorRT Version
8.6.2

• Issue Type( questions, new requirements, bugs)
I want a Graph Composer graph example that uses the Jetson’s onboard CSI camera as input. The reference test graphs tend to crash after a few frames (deepstream-test1 and test2). There does not appear to be any references for CSI inputs. Thanks!

• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)
Run the test graphs with a stock install of JP6, DS7 and Graph Composer 4.0 on the Jetson. Jetson is the gxf_server, Windows 10 or Ubuntu 22 is the client.

What kind of CSI camera? The Argus API supported CSI camera（ Accelerated GStreamer — NVIDIA Jetson Linux Developer Guide 1 documentation）or the ordinary CSI camera which only support V4L2 APIs?

4

The NvDsCameraSrcInput extension can be used as the source input.

Thanks. I am using standard Pi HQ camera (tested and working with JP6 after resistor removal). It is on /dev/video0.

Whenever I attempt to run with Camera Source Input with the device, I get an error. I get it if I run remotely or locally.

Thoughts?

Can you answer the question?

7

Sorry. I am still learning things. I switched from V4L2 to the nvargus setting and it appears to work.

Glad to hear that!
