I’ve retrained a model from detectnet_v2 (resnet 18) by TAO, and it’s running well on my Jetson Nano 2g with file source, the app is a customized Python app (I modified it from official Python sample app: test4), it can achieve 6FPS inference perf.
But see problems when switch the source to a live camera RTSP stream (25fps, 1280*960), the huge time (minutes) lag happened between the inferenced osd and camera live monitor.
I can understand the root cause is the poor perf of the hardware that can’t achieve real-time inference, and may never can’t.
So I wonder is there a way in Python code to drop old frames rather than buffering those un-inferenced frames too much?
