使用Py的CV2录制视频与拍摄图片

import numpy as np
import cv2
#保存自拍
cap = cv2.VideoCapture(0)
cap.set(3,2480)
cap.set(4,1960)
print(str(cap.get(3))+" "+str(cap.get(4)))
time = 0
while time<1000:
    ret,frame = cap.read()
  #  frame = cv2.cvtColor(frame,cv2.COLOR_BGR2GRAY)
    cv2.namedWindow("clip",cv2.WINDOW_NORMAL)
    cv2.imshow("clip",frame)
    cv2.imwrite("C:\\Users\\Administrator\\DeskTop\\jack.jpg",frame)
    cv2.waitKey(100)
    time+=1
cap.release()
cv2.destroyAllWindows()

#保存视频
import cv2
cap = cv2.VideoCapture(0)
fourCC =  cv2.VideoWriter_fourcc(*'MJPG')
#指定视频的名字,编码方式,每秒播放的帧数,每帧的大小
out = cv2.VideoWriter("jack.avi",fourCC,5,(640,480))
while(cap.isOpened()):
    ret,frame = cap.read()
    out.write(frame)
    cv2.imshow("jack",frame)
    code = cv2.waitKey(100)
    if code == ord('A'):
        break;
    else:
        continue;
cap.release()
out.release()
cv2.destroyAllWindows()
