Nvarguscamerasrc does not apply img width height of settings

[honeymax]

I have an Orin connected to an usb camera.
The img can be opened successfully with the following command:

gst-launch-1.0 nvarguscamerasrc sensor_id=0 ! ‘video/x-raw(memory:NVMM), width=(int)3280, height=(int)2464, format=(string)NV12, framerate=(fraction)21/1’ ! nvvidconv ! video/x-raw, format=BGRx ! videoconvert ! appsink drop=1 max-buffers=2

If I try the same command in python with opencv, I get only 1920x1080 resolution, but I set a higher resolution. Any thoughts/ideas ?

import cv2
video_string = “nvarguscamerasrc sensor-id=0 ! video/x-raw(memory:NVMM), width=(int)3280, height=(int)2464, format=(string)NV12 framerate=21/1 ! nvvidconv flip-method=0 ! video/x-raw ! videoconvert ! appsink max-buffers=1 drop=1”
print(str(video_string))
cap = cv2.VideoCapture(video_string, cv2.CAP_GSTREAMER)
assert cap.isOpened(), f’Failed to open cam’

You posted in the wrong place, this topic may be moved to Jetson Orin.

Your issue is caused by a missing comma before framerate in opencv case. As no correct mode has been found, nvarguscamerasrc falls back to default 1080p mode.

Also note that the optimal path from nvarguscamerasrc to BGR processing in opencv would be something like:

video_string = "nvarguscamerasrc sensor-id=0 ! video/x-raw(memory:NVMM), width=(int)3280, height=(int)2464, format=(string)NV12, framerate=21/1 ! nvvidconv flip-method=0 ! video/x-raw,format=BGRx ! videoconvert ! video/x-raw,format=BGR ! appsink max-buffers=1 drop=1"

Hello,

I will move this topic over to the Jetson category for you.

Many thanks, did not see the missing Komma……
