I checked a Nvidia Developer Youtube video ’ DeepStream SDK: Best practices for performance optimization’ link. Here I came to know that the config_* files are secondary files and we must run the files which start form source_* filename. eg: source8_1080p_dec_infer-resnet_tracker_tiled_display_fp16_nano.txt ( this file contains settings optimized for Jetson Nano devices). These files will be present in ’ opt\nvidia\deepstream\deepstream-5.0\samples\configs\deepstream-app ’ folder. The source_* files will call the configs_* file. Thus we must run the source_ files to execute the reference application.

This method to call source_* files worked well and the issue is resolved.
