Multiple Argus Camera in Isaac SDK

Hi @ShaneCCC @JerryChang @hemals Does Argus Component in Isaac SDK support Multiple Cameras, I want to broadcast 3 cameras simultaneously in Isaac SDK.

I don’t clear the relative of Isaac SDK with Argus, however Argus able support 3 cameras.

@dusty_nv Need your valuable Inputs, Right now, I am unable to use multiple streams of nvargus cameras inside Isaac . Now I feel using Deepstream SDK inside Isaac SDK is the only option ?

As mentioned in thread, you should be able to configure multiple ArgusCsiCamera components to make this work in Isaac SDK.


This is my JSON file for your reference : (4.8 KB)

Nope, the Multi Argus Camera does not work !! I am attaching my Json File for your reference and the Error code I am getting is :

@hemals If you guys are so busy and cannot reply to the topic in 1 Week, I think its better to ditch Isaac SDK and switch to ROS full-time !!

The app json seems fine (camera_id set and there are two nodes for ArgusCsiCamera), but the error here indicates that the libArgus camera provider itself was not available to even request which cameras were connected in the first place.
Can you run this demo with just one camera and make sure Argus is running correctly on your device?

This may be an issue with running multiple ArgusCsiCamera codelets however in the same process but we need to confirm that still. Each ArgusCsiCamera codelet tries to create its own CameraProvider through a shared Argus::CameraProvider::create() which may be the issue here.

You could try using the code in the Isaac ROS version of Argus stereo camera here which uses one CameraProvider for two camera capture sessions as a template for implementing your own N-camera ArgusMultiCsiCamera codelet.

@hemals I confirm I can use Single Argus Camera, I think we will have to write a custom codelet for using multiple Argus cameras, If there is an issue with running multiple ArgusCsi Camera.
