# Script MJPEG server > This example can only run on > [OAK POE devices](https://docs.luxonis.com/hardware.md#poe-designs) > . You need > **bootloader** > on/above version > **0.0.15** > . You can flash bootloader by running > `python3 examples/bootloader/flash_bootloader.py` > . This demo runs an HTTP server on the device itself. Server will serve you MJPEG stream when you connect to it. ## Demo When you run the demo, it will print something similar to ```bash Serving at 192.168.1.193:8080 ``` If you open this IP in the browser (eg. chrome), you will see this: if you click on the here href, you will get the MJPEG video stream. For static image, you can check out [Script HTTP server](https://docs.luxonis.com/software/depthai/examples/script_http_server.md). ## Setup Please run the [install script](https://github.com/luxonis/depthai-python/blob/main/examples/install_requirements.py) to download all required dependencies. Please note that this script must be ran from git context, so you have to download the [depthai-python](https://github.com/luxonis/depthai-python) repository first and then run the script ```bash git clone https://github.com/luxonis/depthai-python.git cd depthai-python/examples python3 install_requirements.py ``` For additional information, please follow the [installation guide](https://docs.luxonis.com/software/depthai/manual-install.md). ## Source code #### Python ```python #!/usr/bin/env python3 import depthai as dai import time # Start defining a pipeline pipeline = dai.Pipeline() # Define a source - color camera cam = pipeline.create(dai.node.ColorCamera) # VideoEncoder jpeg = pipeline.create(dai.node.VideoEncoder) jpeg.setDefaultProfilePreset(cam.getFps(), dai.VideoEncoderProperties.Profile.MJPEG) # Script node script = pipeline.create(dai.node.Script) script.setProcessor(dai.ProcessorType.LEON_CSS) script.setScript(""" import time import socket import fcntl import struct from socketserver import ThreadingMixIn from http.server import BaseHTTPRequestHandler, HTTPServer PORT = 8080 def get_ip_address(ifname): s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) return socket.inet_ntoa(fcntl.ioctl( s.fileno(), -1071617759, # SIOCGIFADDR struct.pack('256s', ifname[:15].encode()) )[20:24]) class ThreadingSimpleServer(ThreadingMixIn, HTTPServer): pass class HTTPHandler(BaseHTTPRequestHandler): def do_GET(self): if self.path == '/': self.send_response(200) self.end_headers() self.wfile.write(b'
