Nginx ,Nginx-Rtmp-Module & Ffmpeg Build Live Video Streaming Server

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 https://www.mongodb.com/download-center?jmp=nav#community or use Home brew 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 https://www.ffmpeg.org/download.html or use Home brew to install it on MacOs.

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 https://www.ffmpeg.org/ffmpeg-devices.html On MacOs

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
