• 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)

It depends on what you have put after SGIE in the pipeline, some DeepStream plugin will generate new NvDsMeta for the output, the parent is not reserved in the new NvDsMeta.
