fps drop #425

Open mztony opened 10 months ago

mztony commented 10 months ago

hi, i encounter a problem that the fps change using different camera-height and camera-width. I connected 3 same usb camera to my jetson nx. When i set their camera-width to 640 and camera-height to 480, they worked well and the fps was around 31 for each. But, after i changed the camera-width to 1280 and camera-height to 480, one camera had only 20 fps and the other two had 0 fps. Do u have any solution ? Thanks u in advance!

Are you changing the model inference size or the streammux size? Or just changing the camera resolution?

I just change the camera resolution

marcoslucianops commented 10 months ago

The input resolution should not affect the pipeline in this case. Can you check the CPU usage with the higher resoltion in the camera?

Same issue here -getting 20 FPS on a 30FPS camera. Using yolov8s - using input size of 640 X 480.
