a pipeline composed of bellow plugins :
v4lsrc + nvinfer(pgie) + nvtracker + nvdsosd

we run it in 2 different cases. one with gstreamer and the other with deepstream-app application.
Is fps and latency different in 2 cases? I need accurate results if nvidia has measured.

You can check performance result from here. Performance — DeepStream 6.1.1 Release documentation
Make sure you use same components in your gst launch pipeline as deepstream-app to compare the perf and latency.

Same topic discussed in Deepstream-app vs gstreamer - Intelligent Video Analytics / DeepStream SDK - NVIDIA Developer Forums, so close this one.
