使用opencv和python实现可变帧率的IP摄像机视频录制

import cv2
import time

camera_ip = "摄像机IP地址"
camera_port = "摄像机端口"

fourcc = cv2.VideoWriter_fourcc(*'XVID')
output_file = "output.avi"
output = cv2.VideoWriter(output_file, fourcc, 30.0, (640, 480))

camera = cv2.VideoCapture(camera_ip + ":" + camera_port)
while True:
    ret, frame = camera.read()
    if not ret:
        break
    output.write(frame)
    cv2.imshow("Recording", frame)
    if cv2.waitKey(1) == ord('q'):
        break

camera.release()
output.release()
cv2.destroyAllWindows()
