Use opencv to frame the video and save it

To use the cv2.imwrite() function, you need to import the cv2 library

#path为视频文件地址
cap = cv2.VideoCapture(path)

#vedio_save_path为图片分帧地址，注意不能写成path，后面要记得再加一个/
vedio_save_path='path/'

#用来给图片依次命名
c=0

while cap.isOpened():
    #success表示图片帧是否接收成功，image表示每一帧图片
    success, image = cap.read()
    if not success:
        print("Ignoring empty camera frame.")
        continue

    #保存每一帧图片(第一个参数为保存地址，第二个为image)
    cv2.imwrite(vedio_save_path + str(c) + '.jpg', image) 
    c+=1

    # 展示每一帧图片(window_name为字符串，可以自己设置)
    cv2.imshow('window_name', image)

    # 窗口按q退出
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break
