• Hardware Platform: dGPU
• DeepStream Version: 6.1.1
• TensorRT Version: 8.4

• NVIDIA GPU Driver Version (valid for GPU only): 516.94
• cuDNN Version: 8.4
• Issue Type: bugs
• Sample app: deepstream-test1
• Configuration file: dstest1_pgie_config.txt
• Bug description:

After carefully following the instrustions available in Quickstart Guide — DeepStream 6.1.1 Release documentation
This is what happens when I try to run the first testing app:

./deepstream-test1-app /opt/nvidia/deepstream/deepstream-6.1/samples/streams/sample_720p.h264

One element could not be created. Exiting.

Moreover, I tried the reference application:

deepstream-app -c config_infer_primary.txt

** ERROR: <main:716>: Failed to set pipeline to PAUSED Quitting ERROR from src_bin_muxer: Output width not set Debug info: gstnvstreammux.c(2809): gst_nvstreammux_change_state (): /GstPipeline:pipeline/GstBin:multi_src_bin/GstNvStreamMux:src_bin_muxer App run failed

I looked at /usr/lib/x86_64-linux-gnu/gstreamer-1.0 folder where I did not find the deepstream folder that must be created during the installation of deepstream.

whenever I run:

deepstream-app

I get:

Could you please provide some options to solve this issue?

After run install.sh, you will see the deepstream folder under /usr/lib/x86_64-linux-gnu/gstreamer-1.0
please use gpu driver version 515.65

I tried to install the gpu driver version 515.65 but it seems that it is not available on windows.

Did you run deepstream on windows?

In fact, we are using WSL2.

We never test and maintain on WSL2.

Thank you for your feedback,
any plans to consider this in the future releases of DS please?
