Fail with deepstream example

I’m trying to test deepstream in my jetson Xavier AGX.
After install deepstream with the sdkmanager, I try to execute:

deepstream-app -c /opt/nvidia/deepstream/deepstream-5.0/samples/configs/deepstream-app/source4_1080p_dec_infer-resnet_tracker_sgie_tiled_display_int8.txt

The result is the following error:

** ERROR: <create_multi_source_bin:1057>: Failed to create element ‘src_bin_muxer’
** ERROR: <create_multi_source_bin:1132>: create_multi_source_bin failed
** ERROR: <create_pipeline:1296>: create_pipeline failed
** ERROR: main:636: Failed to create pipeline
App run failed

I’m searching and some people say it works if they clear the cache of gstreamer and change:

export DISPLAY=:0

But I try with that and changing the number and I have the same result.

Any ideas?
Thanks in advance

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU)
• DeepStream Version
• JetPack Version (valid for Jetson only)
• TensorRT Version
• NVIDIA GPU Driver Version (valid for GPU only)
• Issue Type( questions, new requirements, bugs)
• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)
• Requirement details( This is for new requirement. Including the module name-for which plugin or for which sample application, the function description)

Can you run “gst-inspect-1.0” in your board? What is the result?

First of all, you can delete Gstreamer cache

If it does not help, check your applications packages. Maybe something got wrong in your DeepStream installation. You can check it like that:

ldd /opt/nvidia/deepstream/deepstream-5.0/bin/deepstream-app
