i used the command export DISPLAY=:1
gst-launch-nvarguscamerasrc ! nvvidconv ! autovideosink

iam able to get the output
I need to test all the interfaces in the device , so i need to validate the whole interfaces in superuser

When i run the same command in root terminal
Iam not able to get the output

Hi,
Orin Nano developer kit has only DP output. Do you use Orin Nano module + custom carrier board?

4

Custom board
We have connected a hdmi
we can see the hdmi
If i run the command without root i can get monitor stream
BUt if i run the same command within root
I can’t get camerastream

Hi,
Please run the command and try again:

$ xhost +
6

did you mean to run this in root terminal ?

and also

$ xhost +  (gst-launch-1.0 ....comand) ??
7

Hi,
Please try

$ export DISPLAY=:0
$ xhost +
$ sudo gst-launch-1.0 videotestsrc ! xvimagesink
8

Then I need to run all commands in sudo
That is my use case

Hi,
We are uncertain how to run the commands into single command. This would need other users to share experience.

10

How about changing the sudo permission with no password in firmware in /etc/sudoers

so we can run the command which need sudo like sudo command1 and other command which do not need sudo like command2

will it support??

Hi,
Not sure if the proposal works. You may give it a try.

Another method is to put the command in ~/.xsessionrc:

/usr/bin/xhost +

And then after booting, you can run the command:

$ sudo DISPLAY=:0 gst-launch-1.0 videotestsrc ! xvimagesink
