使用opencv-python录视频

import cv2#导入opencv包 video=cv2.VideoCapture(0)#打开摄像头 fourcc = cv2.VideoWriter_fourcc(*'XVID')#视频存储的格式 fps = video.get(cv2.CAP_PROP_FPS)#帧率 #视频的宽高 size = (int(video.get(cv2.CAP_PROP_FRAME_WIDTH)), \ int(video.get(cv2.CAP_PROP_FRAME_HEIGHT))) out = cv2.VideoWriter('video.avi', fourcc, fps, size)#视频存储 while out.isOpened(): ret,img=video.read()#开始使用摄像头读数据，返回ret为true，img为读的图像 if ret is False:#ret为false则关闭 exit() cv2.namedWindow('video',cv2.WINDOW_AUTOSIZE)#创建一个名为video的窗口 cv2.imshow('video',img)#将捕捉到的图像在video窗口显示 out.write(img)#将捕捉到的图像存储 #按esc键退出程序 if cv2.waitKey(1) & 0xFF ==27: video.release()#关闭摄像头 break
