Creating multi source bin failed on pipeline restart

[edit_or]

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU) Orin 64G
• DeepStream Version7.1

I am experimenting with deepstream application.
In my test, the whole pipeline is implemented in a separate function called
int pipelineRunning(int argc, char *argv[]){}. So whatever inside main() is implemented in pipelineRunning() function.
The start/stop main_loop is implemented in pipelineRunning function.
When I stop the whole pipeline using g_main_loop_quit(main_loop);, all the following codes are processed to stop the pipeline.

done:
  
  g_print ("Deepstream Quitting\n");
  
  //Disconnect mqtt done
  if (bus_watch_id) {
    g_print("Returned, stopping playback\n");
    gst_element_set_state(pipeline->pipeline, GST_STATE_NULL);
    g_print("Deleting pipeline\n");
    gst_object_unref(GST_OBJECT(pipeline->pipeline));
    g_source_remove(bus_watch_id);
  }

  if (appCtx) {
    if (appCtx->return_value == -1)
      return_value = -1;
    g_free (appCtx);
  }

  if (main_loop) {
    g_main_loop_unref (main_loop);
  }

  if (ctx) {
    g_option_context_free (ctx);
  }

  if (return_value == 0) {
    g_print ("App run successful\n");
  } else {
    g_print ("App run failed\n");
  }

  gst_deinit ();
  return return_value;

But when the pipeline is restart again, I have the following error.

creating multi source bin failed
Deepstream Quitting
App run successful

(deepstream-parallel-infer:6213): GStreamer-ERROR **: 16:38:01.632: GStreamer should not be deinitialized a second time.
Trace/breakpoint trap (core dumped)

How to solve the issue?

Can you try to add a delay time before restarting? Please unref all the pipeline element and plugins before restarting.
