Python OpenCV2 cv2.cv_fourcc 不适用于 VideoWriter

Question

如标题所述，当我运行 cv2.videowriter 函数时，我得到“模块”对象没有属性 CV_FOURCC。

代码:

# Creates a video file from webcam stream
import cv2

Create test window
cv2.namedWindow("cam_out", cv2.CV_WINDOW_AUTOSIZE)

# Create vid cap object
vid = cv2.VideoCapture(1)


# Create video writer object
vidwrite = cv2.VideoWriter(['testvideo', cv2.CV_FOURCC('M','J','P','G'), 25, 
               (640,480),True])

Answer 1

聚会有点晚了，但如果有人需要它用于更新版本的 opencv2，那么命令是:

cv2.VideoWriter_fourcc(c1, c2, c3, c4)
