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](https://www.youtube.com/watch?v=TdELN27NkyY)

#### 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/](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](https://www.mongodb.com/download-center?jmp=nav#community) or use Home brew [https://docs.mongodb.com/manual/tutorial/install-mongodb-on-os-x/](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/](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](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](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

#### 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/*;}
