它采用 RTSP 协议生成的流并使用机器学习算法对其进行处理，但效果不佳，该算法处理帧的速度很慢，因此我试图将流保存到小视频中，但我得到的帧速率非常小1FPS，当我尝试保存 1 分钟时，使用 IP 摄像头海康威视只给了我 15 秒这是正在使用的代码。 

import time
import cv2
import numpy as np
import cv2
import imutils
from imutils.object_detection import non_max_suppression
import datetime
import numpy as np
import cv2 as cv


capture_duration = 60

for i in range(1,4):
    cap = cv2.VideoCapture("rtsp://admin:admin123@192.168.1.2:554/cam/realmonitor?channel=1&subtype=0")
    width = int(cap.get(cv2.CAP_PROP_FRAME_WIDTH) )
    height = int(cap.get(cv2.CAP_PROP_FRAME_HEIGHT) )
    size = (width, height)
    fourcc = cv2.VideoWriter_fourcc(*'XVID')
    name=( str(i)+'.mp4')
    out = cv2.VideoWriter(name, fourcc, 10.0, size)
    start_time = time.time()

    while(int(time.time() - start_time) < capture_duration):
        _, frame = cap.read()
        #cv2.imshow('Recording...', frame)
        out.write(frame)
        if cv2.waitKey(1) & 0xFF == ord('q'):
            break

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