将实时视频帧发送到套接字服务器，然后将实时视频帧返回给客户端

Question

我正在尝试将视频从客户端发送到服务器，并在服务器中进行了面部检测处理后，最终希望实时视频流再次在客户端显示。问题是我运行代码时客户端没有将帧不断发送到服务器。客户端只发送一次视频帧。同时，我得到空的无响应窗口。

这是代码：-

server.py
import socket
import sys
import cv2
import pickle
import numpy as np
import struct 
import logging as log
import datetime as dt
from time import sleep

cascPath = "/haarcascade_frontalface_default.xml"
faceCascade = cv2.CascadeClassifier(cascPath)
log.basicConfig(filename='webcam.log',level=log.INFO)
anterior = 0
HOST=''
PORT=2222

s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
print ('Socket created')

s.bind((HOST,PORT))
print ('Socket bind complete')
s.listen(10)
print ('Socket now listening')

conn,addr=s.accept()


data = b''
payload_size = struct.calcsize("L") 
while True:
    while len(data) < payload_size:
        data += conn.recv(4096)
    packed_msg_size = data[:payload_size]
    data = data[payload_size:]
    msg_size = struct.unpack("L", packed_msg_size)[0]
    while len(data) < msg_size:
        data += conn.recv(4096)
    frame_data = data[:msg_size]
    data = data[msg_size:]
    ###



    frame=pickle.loads(frame_data)
    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

    faces = faceCascade.detectMultiScale(
        gray,
        scaleFactor=1.1,
        minNeighbors=5,
        minSize=(30, 30)
    )

    # Draw a rectangle around the faces
    for (x, y, w, h) in faces:
        a=cv2.rectangle(frame, (x, y), (x+w, y+h), (0, 255, 0), 2)
        print(a)

        data1 = pickle.dumps(a)
        conn.sendall(struct.pack("L", len(data1))+data1)

client.py

import cv2
import numpy as np
import socket
import sys
import pickle
import struct 

cap=cv2.VideoCapture(0)
clientsocket=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
clientsocket.connect(('localhost',2222))

while True:
    ret,frame=cap.read()
    data = pickle.dumps(frame)
    clientsocket.sendall(struct.pack("L", len(data))+data)
    data = b''
    payload_size = struct.calcsize("L") 
    while True:
        while len(data) < payload_size:
            data += clientsocket.recv(4096)
        packed_msg_size = data[:payload_size]
        data = data[payload_size:]
        msg_size = struct.unpack("L", packed_msg_size)[0]
        while len(data) < msg_size:
            data += clientsocket.recv(4096)
        frame_data = data[:msg_size]
        data = data[msg_size:]
        ###



        frame=pickle.loads(frame_data)
        print(frame)
        cv2.imshow('frame',frame)
        # add this
        if cv2.waitKey(1) & 0xFF == ord('q'):
            break
