Nvyolo plugin in gstreamer pipeline

I am attempting to run the deepstream nvyolo plugin to process a streaming video over a network. When I try to test directly creating the gstreamer pipeline

$ gst-launch-1.0 -v udpsrc port=1234 ! h264parse ! omxh264dec ! nvvidconv ! nvyolo ! nvosd ! nvoverlaysink

I receive the error: Yolo plugin config file path not set

Any advice on how to fix this is greatly appreciated.

Please refer to source code of deepstream-yolo-app. You need to set

g_object_set (G_OBJECT (yolo), "config-file-path", argv[3], NULL);
