opencv camera

MacOS在用 opencv 调用摄像头时出错

cap = cv2.VideoCapture(1)

OpenCV: out device of bound (0-0): 1

   OpenCV: camera failed to properly initialize!

将cv2.VideoCapture(1) 更改为cv2.VideoCapture(0)

It is a MacOS bug for Coaca applications.原文连接：https://github.com/Classical-machine-learning/invisiblityCloak/issues/3

你是用terminal执行的吗？在系统安全设置里面把terminal调用摄像头的权限开启
