Build Python App for Raspberry Pi Live Streaming video from Camera to Server Setup and create app for RaspberryPi 3, pi Zero w stream video from camera to the server use Python Language. Setup Server for Live Video Streaming See this post Tool for development Python I recommend use Pycharm really cool for you and for me. Just donwload community version it’s free https://www.jetbrains.com/pycharm/download Setup Python on Development Enviroment When we deploy the app to Raspberry Pi we don’t have to install Python because it enabled by default MacOs & on Raspberry Pi devices. (Pi 3, Pi Zero W…) Download and install Python here https://www.python.org/downloads/ Setup Pip (Python Package Index) We use Pip to manage all python packages, so to setup Pip just follow this For Ubuntu or other linux i recommend follow this doc: https://pip.pypa.io/en/latest/installing/ https://packaging.python.org/guides/installing-using-linux-tools/#installing-pip-setuptools-wheel-with-linux-package-managers curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

sudo python get-pip.py Websocket client library autobahn-python is good library we will use for Websocket Client in this project so our RaspberryPi will connect to websocket server as client. and we may control it to capture video/picture or stop any time. we can check it status is connected to internet or offline. https://github.com/crossbario/autobahn-python pip install autobahn[twisted] On MacOs if you are getting an error after running that command use following command pip install autobahn[twisted] --user Python Libraries we will use autobahn,twisted,subprocess Sample code use subprocess cmd = 'ffmpeg -re -i /Users/toan/Tutorials/stream/video.mkv -c:v libx264 -preset veryfast -maxrate 3000k -bufsize 6000k -pix_fmt yuv420p -g 50 -c:a aac -b:a 160k -ac 2 -ar 44100 -f flv rtmp://localhost/live/tabvn'subprocess.call(cmd, shell=True) OR use Popen cmd = 'ffmpeg -re -i /Users/toan/Tutorials/stream/video.mkv -c:v libx264 -preset veryfast -maxrate 3000k -bufsize 6000k -pix_fmt yuv420p -g 50 -c:a aac -b:a 160k -ac 2 -ar 44100 -f flv rtmp://localhost/live/tabvn'streaming_process = subprocess.Popen(cmd, shell=True, stdin=subprocess.PIPE) Sample Python App for Websocket client Watch Video: https://www.youtube.com/watch?v=cV8uwjV4kaE Github: https://github.com/tabvn/video-streaming-service
