This document is setup development enviroment on MacOs. For other Linux such at Ubuntu cloud server we will do later on Deployment task. Watch video here Install Node.js We need nodejs for development and run backend resful service , websocket server so to install Node.js just download this package from officical website https://nodejs.org/en/download/ Install MongoDB This tutorial we are using Mongodb NoSQL database store document for our Node.js app. To instlal MongoDB just download or use Home brew https://www.mongodb.com/download-center?jmp=nav#community https://docs.mongodb.com/manual/tutorial/install-mongodb-on-os-x/ Install Nginx + Nginx Rtmp Module (MacOs) We use home brew to install package if you dont have Home brew just see documentation to install home brew on your MacOs https://brew.sh/ brew tap homebrew/nginx brew options nginx-full brew info nginx-full brew install nginx-full --with-rtmp-module --with-debug Nginx config file for default in /usr/local/etc/nginx/nginx.conf Start Nginx nginx Stop Nginx nginx -s stop Reload Nginx nginx -s reload Setup ffmpeg on MacOs Ffmpeg that is awesome and free tools for video converting, streaming, we will use this tool for stream video from a camera (on Raspberry Pi Zero W) and send stream video from camera to our Server or Youtube. for development we use it on Mac for testing and just stream a video source from a input movie .mkv format. We can download and install package directly from official website or use Home brew to install it on MacOs. https://www.ffmpeg.org/download.html brew install ffmpeg Or Install with extra resources (Plugins) brew install ffmpeg --with-tools --with-fdk-aac --with-freetype --with-fontconfig --with-libass --with-libvorbis --with-libvpx --with-opus --with-x265 Update Ffmpeg to latest version brew update && brew upgrade ffmpeg Documentation for list all inputs videos/audios On MacOs https://www.ffmpeg.org/ffmpeg-devices.html ffmpeg -f avfoundation -list_devices true -i "" Stream Camera on MacOs + Audio to rtmp server ,remember change frame rate correctly in my iMac it: -r 30 ffmpeg -f avfoundation -r 30 -i "0:0" -deinterlace -vcodec libx264 -pix_fmt yuv420p -preset medium -g 60 -b:v 2500k -acodec libmp3lame -ar 44100 -threads 6 -qscale 3 -b:a 712000 -bufsize 512k -f flv rtmp://localhost/live/tabvn Stream a movie (video.mkv) to Nginx Rtmp Server eg: rtmp://localhost/live/tabvn , that mean you can stream a video/camera to your Youtube live channel by replace the rtmp url with your rtmp://a.rtmp.youtube.com/live2/[stream-name-key] ffmpeg -re -i 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 Nginx Config Sample for Nginx + Nginx Rtmp Module worker_processes auto;events { worker_connections 1024;}# RTMP Configrtmp { server { listen 1935; # Listen on standard RTMP port chunk_size 4000; application live{ live on; deny play all; push rtmp://localhost/play; on_publish http://localhost:3001/api/on-live-auth; on_publish_done http://localhost:3001/api/on-live-done; } application play { live on; # Turn on HLS hls on; hls_nested on; hls_fragment_naming system; #hls_path /Users/toan/Sites/mnt/hls/; hls_path /Users/toan/Tutorials/stream/storage/live/; hls_fragment 3; hls_playlist_length 60; # disable consuming the stream from nginx as rtmp deny play all; } }}# End RTMP Confighttp { default_type application/octet-stream; sendfile off; tcp_nopush on; server { listen 3002; location /live { # Disable cache add_header Cache-Control no-cache; # CORS setup add_header 'Access-Control-Allow-Origin' '*' always; add_header 'Access-Control-Expose-Headers' 'Content-Length'; # allow CORS preflight requests if ($request_method = 'OPTIONS') { add_header 'Access-Control-Allow-Origin' '*'; add_header 'Access-Control-Max-Age' 1728000; add_header 'Content-Type' 'text/plain charset=UTF-8'; add_header 'Content-Length' 0; return 204; } types { application/vnd.apple.mpegurl m3u8; video/mp2t ts; } root /Users/toan/Tutorials/stream/storage/; } } include servers/*;} Next Part: Python WebSocket Client Connect to Node.js WebSocket Server µWebSocket Watch Video: https://www.youtube.com/watch?v=TdELN27NkyY Github: https://github.com/tabvn/video-streaming-service
