Hello.
I am looking for a way to set the detection threshold of the nvinfer at the code level.

The code I tried is as follows.
But this has failed.
(object class ‘GstNvInfer’ has no property named ‘threshold’)

pgie = gst_element_factory_make(“nvinfer”, “primary-nvinference-engine”);
g_object_set(G_OBJECT(pgie), “threshold”, 0.5);

Can you tell me how?
Thanks

nvinfer plugin is opensource. in gst_nvinfer_parse_class_attrs, you can see “threshold” corresponds plugin’s preClusterThreshold property.
