Python3 detect. Py - source 0 - weights yolov5s. Pt

I'm jetson run on nano yolov5 detect. Py real-time detection, FPS is very low, only 2, but I see others run FPS is around 10 online, then I see the input of the camera is 2304 * 1536, so I think it should be the resolution of the camera input is too high, lead to reasoning slow, so I want to ask, how to change the input resolution of cameras? I use a Logitech C920 Pro Webcam,


Thank you very much
