Question

大家好，我有这个 python 代码，它可以将实时视频从客户端发送到服务器，它运行良好，直到我添加了服务器在接收实时源时向客户端发送“hello”的行，它停止工作. 客户端使用多线程，一种用于接收，一种用于发送实时提要。有什么关于如何解决这个问题的帮助吗？。

这是我的服务器代码：

import socket, cv2, pickle, struct
import threading
import pyshine as ps

server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
host_name = socket.gethostname()
host_ip = socket.gethostbyname(host_name)
print('HOST IP:', host_ip)
port = 9999
socket_address = (host_ip, port)

print("Listening at", socket_address)
i=0

def show_client(addr, client_socket):
    try:
        print('CLIENT {} CONNECTED!'.format(addr))
        if client_socket:  # if a client socket exists
            data = b""
            payload_size = struct.calcsize("Q")
            while True:
                while len(data) < payload_size:
                    packet = client_socket.recv(4 * 1024)  # 4K
                    if not packet: break
                    data += packet
                packed_msg_size = data[:payload_size]
                data = data[payload_size:]
                msg_size = struct.unpack("Q", packed_msg_size)[0]

                while len(data) < msg_size:
                    data += client_socket.recv(4 * 1024)
                frame_data = data[:msg_size]
                data = data[msg_size:]
                frame = pickle.loads(frame_data)
                text = f"CLIENT: {addr}"
                frame = ps.putBText(frame, text, 10, 10, vspace=10, hspace=1, font_scale=0.7,
                                    background_RGB=(255, 0, 0), text_RGB=(255, 250, 250))
                cv2.imshow(f"FROM {addr}", frame)
                client_socket.sendall('hello')  # send back to client

                key = cv2.waitKey(1) & 0xFF
                if key == ord('q'):
                    break
            client_socket.close()
    except Exception as e:
        print(f"CLINET {addr} DISCONNECTED")
        pass

server_socket.bind(socket_address)
server_socket.listen()

while True:
    client_socket, addr = server_socket.accept()
    thread = threading.Thread(target=show_client, args=(addr, client_socket))
    thread.start()
    print("TOTAL CLIENTS ", threading.activeCount() - 1)

这是我的客户端代码：


import socket,cv2, pickle,struct
import imutils # pip install imutils
import threading
import sys

camera = True
if camera == True:
    vid = cv2.VideoCapture(0)
else:
    vid = cv2.VideoCapture('resources/video3.mp4')
client_socket = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
host_ip = '192.168.100.22' # Here according to your server ip write the address
i=1
port = 9999
client_socket.connect((host_ip,port))
def sendvid():

    while True:
        try:
            if client_socket:
                while True:
                    try:
                        img, frame = vid.read()
                        frame = imutils.resize(frame,width=380)
                        a = pickle.dumps(frame)
                        message = struct.pack("Q",len(a))+a
                        client_socket.sendall(message)
                        #print(client_socket.recv(16))
                        cv2.imshow(f"TO: {host_ip}",frame)
                        key = cv2.waitKey(1) & 0xFF
                        if key == ord("q"):
                            client_socket.close()

                    except:
                        print('VIDEO FINISHED!')
                        break
    

def recv():
    while True:
        print('client_socket.recv(16)')
        print(client_socket.recv(16))

thread1 = threading.Thread(target=sendvid)
thread1.start()
print("hello")
thread2 = threading.Thread(target=recv)
thread2.start()

客户端-服务器：客户端没有从服务器接收任何数据
