Python OpenCV 将摄像头/视频写入视频文件

FourCC就是一个四字节码，用来确定视频的编码格式。

可用的编码列表可以从fourcc.org查到。

# -*- coding: utf-8 -*-

import numpy as np
import cv2

cap = cv2.VideoCapture(0)

fourcc = cv2.VideoWriter_fourcc(*‘XVID‘)
out = cv2.VideoWriter(‘test.avi‘, fourcc, 20.0, (640, 480))

while cap.isOpened():
    ret, frame = cap.read()

    if ret == True:
        frame = cv2.flip(frame, 0)

        out.write(frame)

        cv2.imshow(‘frame‘, frame)

        if cv2.waitKey(1) & 0xff == ord(‘q‘):
            break
    else:
        break

cap.release()
out.release()
cv2.destroyAllWindows()
