opencv python 读取摄像头数据录制视频

 

import cv2

cap = cv2.VideoCapture(1, cv2.CAP_DSHOW)
cap.set(cv2.CAP_PROP_FRAME_WIDTH, 1920); #宽度

cap.set(cv2.CAP_PROP_FRAME_HEIGHT, 1080); #高度

cap.set(cv2.CAP_PROP_FPS, 30); #帧率 帧/秒

fourcc = cv2.VideoWriter_fourcc('X', 'V', 'I', 'D')

out = cv2.VideoWriter('testwrite.avi', fourcc, 30.0, (1920, 1080), True)

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

        cv2.imshow('frame', frame)
        out.write(frame)

        if cv2.waitKey(10) & 0xFF == ord('q'):
            break
    else:
        break

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