Error: gst-stream-error-quark

I am facing a problem launching the deepstream app using a webcam on my Jetson Nano 2 GB, Jetpack 4.4.1 and deepstream 5.0.

I am having the following error:
Creating Pipeline

I guess it is something related to the usb camera. But I tried it and it is working fine.
Can I please get help about this issue?


This looks like Deepstream related. We are moving this post to the Deepstream forum to get better help.

Thank you.

Please upgrade to the latest DeepStreamSDK 6.0.1. Quickstart Guide — DeepStream 6.1.1 Release documentation
How did you run the case?
With deepstream-app?

need to check camera uage, similar to this issue: Error:gst-stream-error-quark
