cv2循环读取文件夹视频

Posted 2021-11-24 杨旭华啊

import os

import cv2
import time

for item in os.listdir(r"D:\\airplane\\output"):
    video = r"D:\\airplane\\output" + "\\\\" + item

    cap = cv2.VideoCapture(video)
    ret, frame = cap.read()
    print("正在读取:", video)
    while ret:

        cv2.imshow("capture", frame)
        # sleep是因为有的视频播放速度本身就是几倍播放的，所以想慢一点可以sleep一下，删除也没事
        time.sleep(0.5)
        if cv2.waitKey(100) & 0xFF == ord('q'):
            cap.release()
            break
        ret, frame = cap.read()
