[英]Cannot Video Capture With opencv on macOS
在 python 上,当我尝试使用 open cv2 进行视频捕获时,我得到:

我也是这个 windows 开口:
这是我的代码:
import cv2
trained_face_data = cv2.CascadeClassifier('haarcascade_frontalface_default.xml')
webcam = cv2.VideoCapture(0)
ret, frame = webcam.read()
grayscaled_img = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
cv2.imshow('image face detector', grayscaled_img)
cv2.waitKey(1)
解决只需将参数cv2.VideoCapture(0)
更改为cv2.VideoCapture(2)
希望对其他 Mac 用户有所帮助
