ubuntu18.04进行摄像头操作出现GStreamer警告

Question

ubuntu18.04，opencv4,运行如下代码

from jetcam.csi_camera import CSICamera
import cv2
camera0 = CSICamera(capture_device=0, width=680, height=480)
image0 = camera0.read()
print(image0.shape)
print(camera0.value.shape)
while 1:
    image0 = camera0.read()
    cv2.imshow("CSI Camera0", image0)
    kk = cv2.waitKey(1)
    if kk == ord('q'):  # 按下 q 键，退出
        break

from jetcam.csi_camera import CSICamera
import cv2
camera0 = CSICamera(capture_device=0, width=680, height=480)
image0 = camera0.read()
print(image0.shape)
print(camera0.value.shape)
while 1:
image0 = camera0.read()
cv2.imshow("CSI Camera0", image0)
kk = cv2.waitKey(1)
if kk == ord('q'): # 按下 q 键，退出
break

出现[ WARN:0] global /home/hxy/opencv-4.1.2/modules/videoio/src/cap_gstreamer.cpp (933) open OpenCV | GStreamer warning: Cannot query video position: status=0, value=-1, duration=-1
请问这是怎么回事呀，我在windows笔记本anaconda试过是正常的，难道opencv坏掉了么
