Video Chat App

Task Description 📄

📌 Create Live Streaming Video Chat App without voice using cv2 module of Python:

Server Side Code (“Server.py”)

import socket, cv2, pickle,struct

# ----->Socket Creation
server_socket = socket.socket(socket.AF_INET,socket.SOCK_STREAM)

#getting host ip
host_name  = socket.gethostname()
host_ip = socket.gethostbyname(host_name)

#port as user input
port = int(input('Enter the port number----->'))
socket_address = (host_ip,port)

# ---->Socket binding
server_socket.bind(socket_address)

# ----->Socket listening
server_socket.listen(5)
print("listening at: ",socket_address)

# ------>Socket Accepting Clients
while True:
    client_socket,addr = server_socket.accept()

            a = pickle.dumps(frame)
            message = struct.pack("Q",len(a))+a
            client_socket.sendall(message)
            
            cv2.imshow('server cam',frame)
            key = cv2.waitKey(1) & 0xFF
            if key ==ord('q'):
                client_socket.close()

Client Side Code (“Client.py”)
