DS5.0 deepstream-imagedata-multistream sample output to wrong window

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU) Jetson Nano
• DeepStream Version 5.0 with python samples
• JetPack Version (valid for Jetson only) 4.4
• TensorRT Version 7.1.0.16
• NVIDIA GPU Driver Version (valid for GPU only)

I’m using a ssh session to remotely login to Nano device, from a local macbook. If I run xclock, the output is shown on my macbook screen.

But when I launched deepstream-imagedata-multistream natively, it showed segmentation fault.

Segmentation fault (core dumped)

If I ran it inside a docker container, it’s successful, yet displayed the output on Nano’s screen, not on local macbook’s screen. Do not quite understand why x11 forwarding behaves different for xclock and DS5.0 application inside docker.

Hi @bridge
xclock can forward the display.

For docker, with xhost+ as below screenshot, it will use local host’s X display.

Thanks!

I ran ‘xhost +’ before I launched container. I’m pretty sure it was working, regardless of inside/outside docker, or local session/ssh session. But now it didn’t work via ssh session, though ‘xclock’ still work in ssh session. (local session is still good).

Any clue about this weird issue?

I’m looking to make 4 work, i.e show the output on local screen.

Check this,

 On Jetson, running a DeepStream application over SSH (via putty) with X11 forwarding
does not work.

Thanks @Amycao for pointing this out. Wondering any reason why DS5.0 application couldn’t support x11 forwarding via ssh.

Hi Amy,

Does this errata mean that SSH-ing with X11 forwarding doesn’t work only when using Putty? If you’re ssh’ing from a Linux machine, will X11 forwarding work?

Some remote client may support X forward, you can google search for it.
