Hi,
I’ve been facing an error running deepstream_python_apps/apps/runtime_source_add_delete. I run it without modifying anything, I get the following error:

Error: gst-core-error-quark: GStreamer error: state change failed and some element failed to post a proper error message with the reason for the failure. (4): gstbasesink.c(5367): gst_base_sink_change_state (): /GstPipeline:pipeline0/GstNv3dSink:nv3d-sink:
Failed to start

• Hardware Platform (Jetson / GPU) Jetson Xavier NX
• DeepStream Version: 6.2
• JetPack Version (valid for Jetson only): 5.1
• 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):

  • Command line:
    $ python3 deepstream_rt_src_add_del.py file:///opt/nvidia/deepstream/deepstream/samples/streams/sample_720p.mp4

I’ve attached the run-time log.
Thank you for your confirmation.

Best,
Yosuke

Do you have a monitor ? No display may meet error.

If the monitor is plugged, try export DISPLAY=:0.0

thanks.

Thank you for your reply.
