The rtsp on the web consumes a lot of memory - opencv

Question

This is the code I used.
*** client ***
import { React } from "react";
function App() {
return (
<div className="App">
rtsp-streaming
<img src="http://localhost:8086/rtsp_streaming" alt="" />
</div>
);
}
*** server ***
main.py
from urllib import request
from flask import Flask, Response
from rtsp import RTSP_CONNECT
app = Flask(__name__)
def gen(rtsp):
while True:
frame = rtsp.get_frame()
yield (b'--frame\r\n'
b'Content-Type: image/jpeg\r\n\r\n' + frame + b'\r\n\r\n')
#app.route('/rtsp_streaming')
def video_feed():
rtsp_url = "req"
return Response(gen(RTSP_CONNECT(rtsp_url=rtsp_url)),
mimetype='multipart/x-mixed-replace; boundary=frame')
if __name__ == '__main__':
app.run(host='0.0.0.0', port=8086, threaded=True, use_reloader=True)
rtsp.py
import cv2
class RTSP_CONNECT(object):
def __init__(self, rtsp_url):
self.video = cv2.VideoCapture("rtsp://xxxx:xxxx#rtsp_url:rtsp_port/cam/realmonitor?channel=2/subtype=0")
self.video.set(cv2.CAP_PROP_BUFFERSIZE,2)
self.FPS = 1/30
self.FPS_MS = int(self.FPS * 1000)
def __del__(self):
self.video.release()
def get_frame(self):
ret, frame = self.video.read()
ret, jpeg = cv2.imencode('.jpg', frame)
return jpeg.tobytes()
the problem that occurred
It doesn't stop while it's running and goes up constantly.
Also, it actually crashes with a memory leak if left unattended for a long time.
