How does gst-nvtracker report target of first frame in video?

when use nvdcf , i find target reported at sixth frame.I hope it can be report at first frame.So my detector has detected the object, but it doesn’t output until the sixth frame. How do I make it output in the first frame by config?

Check the value of probationAge in your tracker config. If you need to output detections in the first frame, try probationAge = 0.
