Running yolov3 demo using jetson nano and rpi camera

Hi,

It looks like you are meeting the same error of topic 112954:

Question when run yolov3 with camera on-board

Hi, I have flashed my jetson TX2 with Jetpack4.3. and I tried to run yolov3 on the TX2, it works with image detection, and then I would like to do with the camera on-board, I used this command : ./darknet detector demo cfg/coco.data cfg/yolov3.cfg yolov3.weights " nvarguscamerasrc ! video/x-raw(memory:NVMM), width=(int)1280, height=(int)720,format=(string)I420, framerate=(fraction)30/1 ! nvvidconv flip-method=0 ! video/x-raw, format=(string)BGRx ! videoconvert ! video/x-raw, format=(string)BG…

However, the user fixes it by using the NV12 as nvarguscamerasrc output format, which is what I share with you.
To narrow down the issue, could you run this command to see if the camera works without OpenCV first?

gst-launch-1.0 nvarguscamerasrc ! 'video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080, format=(string)NV12, framerate=(fraction)30/1' ! nvvidconv flip-method=3 ! 'video/x-raw(memory:NVMM), width=(int)480, height=(int)640, format=(string)I420' ! nvoverlaysink -e

Thanks.
