[Python] How to send and recieve a cv2 image in the form of numpy array

I'm an intermediate in python and new to libraries like numpy and opencv. I'm trying to make a video calling app using sockets.This code is just a try. I've tried in the following way but as it receives the array it's size becomes 0 and shape becomes null. Please help me do this. I'm sorry for anymistakes I've done

any help will be appreciated

Thank you. Have a nice day enter

Server:-

import socket
import threading
from _thread import *
import cv2
import numpy as np

srvr = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_ip = socket.gethostbyname(socket.gethostname())
port = 9999
client = []
try:
srvr.bind((server_ip, port))
except socket.error as e:
print(e)



def connected_client(conn, addr):
global client
print("[SERVER]: CONNECTED WITH ", addr)
check_msg = "Welcome Client"
conn.send(str.encode(check_msg))
while True:
try:
data = conn.recv(5000)
if not data:
print("[SERVER]: DISCONNECTED..")
break
for i in client:
i.sendall(data)
except:
break

conn.close()


srvr.listen(5)
while True:
print("[SERVER]: STARTED...\n [SERVER]: ACCEPTING CONNECTIONS....")
conn, addr = srvr.accept()
start_new_thread(connected_client, (conn, addr))
client.append(conn)



Client:-

import socket, cv2
import threading
from _thread import *
import numpy as np
import time
import base64

video = cv2.VideoCapture(0)

clt = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
SERVER = socket.gethostbyname(socket.gethostname())
PORT = 9999
ADDR = (SERVER, PORT)

clt.connect(ADDR)
print(clt.recv(2048).decode())
#recieving data from server
def recieve():
global clt
while True:
recv_frame = clt.recv(5000)
nparr = np.frombuffer(recv_frame, np.uint8)
img = cv2.imdecode(nparr, cv2.IMREAD_COLOR)
key = cv2.waitKey(1)
if key == ord('a'):
break
print(img)
# cv2.imshow("aman", recv_frame)

# break

# new thread while to continuously recieve data
start_new_thread(recieve, ())

# loop for continuously sending data
while True:
check, frame = video.read()
str_frame = cv2.imencode('.jpg', frame)[1].tobytes()
clt.sendall(str_frame)


video.release()
cv2.destroyAllWindows()
