Display deepstream-nvdsanalytics-test over ssh

Accelerated Computing Intelligent Video Analytics DeepStream SDK

Please provide complete information as applicable to your setup.
• Hardware Platform (Jetson / GPU): Jetson Nano
• DeepStream Version: 6.0
• JetPack Version (valid for Jetson only) 4.6.3

I’m using deepstream-nvdsanalytics-test on Nano with a DevKit and HDMI screen connected : it works well.

Now, I would like de to use this Nano on our custom carrier board without HDMI connector and use SSH.

I have already read some links about this needed:

  • XForwarding is enable into “/etc/ssh/sshd_config”: X11Forwarding yes
  • I’m using export X on ssh command: “ssh -X…”
  • Environment variable DISPLAY is set to “DISPLAY=localhost:11.0” by default when I’m logged with ssh
  • xrandr: xrandr.txt (2.8 KB)
  • “xclock” application is well displayed on my PC

“deepstream-nvdsanalytics-test” is not working anymore:

No EGL Display
nvbufsurftransform: Could not get EGL display connection

With “unset DISPLAY”, the “deepstream-nvdsanalytics-test” and xclock" is not working anymore:

** ERROR: main:754: Could not open X Display

I don’t want to sink into a RTSP server for the moment, it’s not useful for the tests.

I have read that “We don’t support X11 forwarding on L4T by default.” into this post Export deepstream output display over SSH on Jetson Nano - #3 by DaneLLL

Thanks for your help.

We need some time to investigate whether we can support XForwarding on Jetson. Will be back when we get any information.

What is the reason for “it’s not useful for the tests”?

5

We are using short videos as input for tests, not enough time to connect to the stream.

To display the rtsp stream will not impact the short videos as input.
