HI,
Do you install nvidia related library to system path? or you need to export GST_PLUGIN_PATH
to point to your local path, here is one reference

export GST_PLUGIN_PATH=/home/tse/work/deepstream/DeepStream_Release/usr/lib/x86_64-linux-gnu/gstreamer-1.0:
also you need export LD_LIBRARY_PATH to point to /DS path/usr/local/deepstream, cv, tensorrt, if you do not
install to system path.

please do these and try again.
