Can you refer to this instruction of dumping gstreamer pipeline graph [DeepStream SDK FAQ - Intelligent Video Analytics / DeepStream SDK - NVIDIA Developer Forums](https://forums.developer.nvidia.com/t/deepstream-sdk-faq/80236/10) and dump your graph for checking? The name of the dot file may be different but it is the dot file which can be converted in to png picture.
