Video Streaming on Premium CPU-Optimized Droplets

Setting up video streaming on DigitalOcean’s premium CPU-optimized droplets can offer high performance for encoding, streaming, and handling multiple simultaneous connections. Below is a step-by-step guide to deploy a video streaming server using FFmpeg and Nginx with RTMP (Real-Time Messaging Protocol) module.

1. Log in to DigitalOcean:
   • Go to your DigitalOcean dashboard.
2. Create a New Droplet:
   • Click "Create" in the top right corner and select "Droplets".
   • Choose an image (Ubuntu 22.04 LTS is recommended).
   • Select a premium CPU-optimized droplet plan. For video streaming, you’ll need a plan with higher CPU and memory.
   • Choose a data center region close to your audience.
   • Add your SSH key for secure access.
   • Click "Create Droplet".
3. Step 2: Access Your Droplet
   • SSH into Your Droplet:
     • Open a terminal on your local machine.
     • Connect to your droplet using its IP address:

                                       
                                           ssh root@your_droplet_ip
                                       
                                   

1. Update Your System:

                   
                       sudo apt update
                       sudo apt upgrade -y                    
                   
               

2. Install Nginx and Dependencies:

                   
                       sudo apt install -y build-essential libpcre3 libpcre3-dev libssl-dev zlib1g zlib1g-dev
                   
               

3. Install FFmpeg:

                   
                       sudo apt install -y ffmpeg
                   
               

4. Download and Install Nginx with RTMP Module:

                   
                       cd /usr/local/src
                       sudo git clone https://github.com/arut/nginx-rtmp-module.git
                       sudo wget http://nginx.org/download/nginx-1.20.1.tar.gz
                       sudo tar -zxvf nginx-1.20.1.tar.gz
                       cd nginx-1.20.1
                       
                       sudo ./configure --with-http_ssl_module --add-module=../nginx-rtmp-module
                       sudo make
                       sudo make install                    
                   
               

1. Edit Nginx Configuration:

                   
                       sudo nano /usr/local/nginx/conf/nginx.conf
                   
               

2. Add RTMP Module Configuration:

   Add the following at the end of the file:

                   
                       rtmp {
                           server {
                               listen 1935;
                               chunk_size 4096;
                       
                               application live {
                                   live on;
                                   record off;
                               }
                           }
                       }
                       
                       http {
                           include       mime.types;
                           default_type  application/octet-stream;
                       
                           sendfile        on;
                           keepalive_timeout  65;
                       
                           server {
                               listen       8080;
                               server_name  localhost;
                       
                               location / {
                                   root   html;
                                   index  index.html index.htm;
                               }
                       
                               location /live {
                                   types {
                                       application/vnd.apple.mpegurl m3u8;
                                       video/mp2t ts;
                                   }
                                   alias /tmp;
                                   add_header Cache-Control no-cache;
                               }
                           }
                       }                    
                   
               

3. Start Nginx:

                   
                       sudo /usr/local/nginx/sbin/nginx
                   
               

1. Start Streaming with FFmpeg:

   Replace your_droplet_ip with your droplet's IP address.

                   
                       ffmpeg -re -i input.mp4 -c:v libx264 -c:a aac -f flv rtmp://your_droplet_ip/live/stream
                   
               

2. Access the Stream:

   Open a media player like VLC and open a network stream with the URL:

                   
                       http://your_droplet_ip:8080/live/stream.m3u8
                   
               

1. Install a Firewall:

                   
                       sudo apt install ufw
                       sudo ufw allow OpenSSH
                       sudo ufw allow 8080/tcp
                       sudo ufw allow 1935/tcp
                       sudo ufw enable                    
                   
               

2. Secure Nginx with SSL:

   Use Let’s Encrypt to secure your server with SSL:

                   
                       sudo apt install certbot
                       sudo certbot certonly --standalone -d your_domain                    
                   
               

3. Update Nginx Configuration for SSL:

   Modify your Nginx config to include SSL settings:

                   
                       server {
                           listen 443 ssl;
                           server_name your_domain;
                       
                           ssl_certificate /etc/letsencrypt/live/your_domain/fullchain.pem;
                           ssl_certificate_key /etc/letsencrypt/live/your_domain/privkey.pem;
                       
                           location /live {
                               types {
                                   application/vnd.apple.mpegurl m3u8;
                                   video/mp2t ts;
                               }
                               alias /tmp;
                               add_header Cache-Control no-cache;
                           }
                       }
