These 4 cameras has the properties:
e-CAM130_CUXVR is a synchronized multiple 4K camera solution for NVIDIA® Jetson AGX Xavier development kit that has up to four 13 MP 4-Lane MIPI CSI-2 camera boards.
When I use Python to capture 4k video with the code:
import cv2 import numpy as np cap=cv2.VideoCapture('gst-launch-1.0 v4l2src ! xvimagesink') while cap.isOpened(): ret, frame = cap.read() npy = cv2.imread(frame) cv2.imshow("", frame) if cv2.waitKey(1) & 0xFF == ord('q'): break
I get the error :
VIDEOIO ERROR: V4L: device gst-launch-1.0 v4l2src ! xvimagesink: Unable to query number of channels
Is there any Gstreamer pipeline recommended to preview these cams with 4k with 19 fps?(It is said on econ systems’ document that I can get 19 fps with 4k resolution.
