使用ThreadedHTTPServer python 3将网络摄像头流发送到多个客户端

Question

我试图制作一个将在其他客户端网络浏览器中显示该服务器的网络摄像头视频的python服务器

我编写了这段代码，但是当我尝试在浏览器中打开链接时，脚本总是崩溃

这是我的代码

import sys 
sys.path.append("cv2") 
import cv2 
from PIL import Image 
import threading 
from http.server import BaseHTTPRequestHandler, HTTPServer 
from socketserver import ThreadingMixIn 
from io import BytesIO 
import time 

capture=None



class CamHandler(BaseHTTPRequestHandler):
    def do_GET(self):
        global capture
        if self.path.endswith('test.html'):
            self.send_response(200)
            self.send_header('Content-type','multipart/x-mixed-replace; boundary=--jpgboundary')
            self.end_headers()
            camId = "0"
            font = cv2.FONT_HERSHEY_SIMPLEX
            fontsize = .8
            while True:
                try:
                    rc,img = capture.read()
                    if not rc:
                        continue
                    imgRGB=cv2.cvtColor(img,cv2.COLOR_BGR2RGB)
                    jpg = Image.fromarray(imgRGB)
                    tmpFile = BytesIO() 
                    jpg.save(tmpFile,'JPEG')
                    self.wfile.write(b"--jpgboundary")
                    self.send_header('Content-type','image/jpeg')
                    self.send_header('Content-length',str(tmpFile.getbuffer().nbytes))
                    self.end_headers()
                    jpg.save(self.wfile,'JPEG')
                    time.sleep(1/60)
                except KeyboardInterrupt:
                    break
            return



class ThreadedHTTPServer(ThreadingMixIn, HTTPServer):
    """Handle requests in a separate thread."""

def main():
    global capture
    capture = cv2.VideoCapture(0)
    capture.set(3,1920)
    capture.set(4,1080)
    global img

    try:
        server = ThreadedHTTPServer(('192.95.69.202', 8091), CamHandler)
        print ("server started on port 8091")
        server.serve_forever()
    except KeyboardInterrupt:
        capture.release()
        server.socket.close()

if __name__ == '__main__':
    main()

当我打开192.95.69.202:8091/test.html服务器脚本崩溃时
