Implemented testing environment on local network.

# app.py

from flask import Flask, render_template, Response
import socket
import numpy as np
import cv2

host = "192.168.1.4"
port = 5005
server_address = (host, port)

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.bind(server_address)
print('starting up on %s:%s' % server_address)

app = Flask(__name__)

def gen():
    while True:
        data, address = sock.recvfrom(65535)
        # nparr = np.frombuffer(data, np.uint8)
        # img = cv2.imdecode(nparr, cv2.IMREAD_COLOR)
        yield (b'--frame\r\n'
               b'Content-Type: image/jpeg\r\n\r\n' + data + b'\r\n')

@app.route('/')
def index():
    return render_template('index.html')

@app.route('/video_feed')
def video_feed():
    return Response(gen(), mimetype='multipart/x-mixed-replace; boundary=frame')

if __name__ == '__main__':
    app.run(ssl_context='adhoc')

Regarding the previous commit, without the option to reuse the addres, when trying to run the server, an error pops up saying that the address is already in use (shown in the image below).

To run the client script user now must provide arguments.

Needed arguments for the client script:

port number (mandatory)
camera number (optional)

If the user uses only one camera than providing the camera number is not necessary.
