**opencv-python 调用os08a10相机造成vim3宕机**
Post a console log of your issue below:
import cv2
cap = cv2.VideoCapture(2)
cap.set(cv2.CAP_PROP_FRAME_WIDTH, 320)
cap.set(cv2.CAP_PROP_FRAME_HEIGHT, 240)
while(1):
success, img = cap.read()
winName = 'Deep learning object detection in OpenCV'
cv2.namedWindow(winName, 0)
cv2.imshow(winName, img)
if cv2.waitKey(1) == ord('q'):
cv2.destroyAllWindows()
break
使用这串代码进行调用时出现了桌面宕机，且无法进入桌面的bug
opencv版本是采用的4.6版本的自行编译版本。
使用的是opencv-dnn 的demo编译的opencv。
