DeepStream on WSL

Accelerated Computing Intelligent Video Analytics DeepStream SDK
,

I’m trying to run the DeepStream SDK on WSL. Following the instructions on the DeepStream On WSL, getting to the Run Deepstream Container chapter and running the command:

“gst-launch-1.0 filesrc location= sample_720p.mp4 ! qtdemux ! h264parse ! nvv4l2decoder ! nveglglessink -v”

And I get the following output:

“Getting pipeline to PAUSED …

What is the problem(s)? I can’t figure it out…
I installed it and fulfilled the prerequisites (NVIDIA Drivers, software version, …)

Is it possible to run DeepStream on WSL using my webcam? I want to use DeepStream in WSL and with my webcam to get used to using the software and make it easier to implement in Jetson

What is the output of the following command line ? I can run this command line normally on my WSL.

echo $DISPLAY

Typically, this value is: 0, Try export DISPLAY=:0.

This depends on the v4l2src plugin, but the plugin is driver-dependent and does not always work on WSL.

4

Running “echo $DISPLAY” the output is :0

So what I have to do to work on WSL?

I think the problem is caused by incorrect installation. You need to check the installation steps.

Are you using docker in wsl? This is the recommended approach.

6

I installed the docker but the error still appears

7

Try reinstalling the GPU driver and restarting wsl using wsl --shutdown in cmd.

In addition, Deepstream on WSL is an alpha release and has many issues.
