Orin nano headless - issue with deepstream

Accelerated Computing Intelligent Video Analytics DeepStream SDK
, ,
1

Hardware Platform: Jetson orin nano dev kit (super) - 8GB
DeepStream Version: 7.1
JetPack Version: 6.2
TensorRT Version: 10.3.0.30
CUDA: 12.6.68

Running deepstream with python bindings, tested with soruces USB camera and cctv using rtsp.

Results are as expected when running with monitor connected but the issue is when running headless, trying to access orin over SSH or VNC.

Getting the following error

“Failed to create EGLImage” is the main issue here.

Tried using fakesink so that there will be no feed.
X11 forwarding is on with SSH session.
X11 forwarding parameters are handled in SSH config file on jetson.

Still getting same error when try to run code over SSH on laptop.

Maybe you need to check your DISPLAY and set the correct value if the monitor is removed.

Thank you for your response! I’m sorry, I didn’t quite follow that. Could you please clarify or provide more details?

The program runs well when orin connected with monitor .
It throws the error mentioned above, only when running headless, i.e., when device is accessed over SSH or without display.

To be more specific, i don’t want the device to be connected to monitor. Once it is connected to network, i should be able to access it on my laptop (on same network) using SSH and run program. But when i do this i get the error.

  1. Is there any physical monitor connected with your Orin Nano board?
  2. What is the result with “echo $DISPLAY” command?

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks
