How To Stream Videos With Nginx and JWPlayer on CentOS

In the age of digital content, video streaming has become an essential service for many businesses and creators. If you’re looking to set up your own video streaming service, using Nginx as your web server and JWPlayer as your video player is an excellent choice. In this blog post, we’ll guide you through the process of streaming videos using Nginx and JWPlayer on a CentOS server.

Prerequisites

Before we start, make sure you have the following:

A CentOS server (CentOS 7 or later recommended).
Root or sudo access to your server.
Basic knowledge of the command line.
Nginx installed on your server.
JWPlayer account (for embedding the player).

If you haven’t set up Nginx yet, you can do so with the following commands:

sudo yum install epel-release
sudo yum install nginx
sudo systemctl start nginx
sudo systemctl enable nginx

Step 1: Install FFmpeg

FFmpeg is a powerful multimedia framework that allows you to convert, stream, and manipulate audio and video files. It’s essential for preparing your video files for streaming.

Install FFmpeg with the following command:

sudo yum install ffmpeg

Verify the installation by running:

ffmpeg -version

Step 2: Prepare Your Video Files

To stream videos effectively, you should encode them in a format that is suitable for web streaming. Use FFmpeg to convert your videos into an appropriate format like HLS (HTTP Live Streaming) or DASH (Dynamic Adaptive Streaming over HTTP).

Here’s a basic command to convert a video to HLS:

ffmpeg -i input.mp4 -codec: copy -start_number 0 -hls_time 10 -hls_list_size 0 -f hls output.m3u8

This command will generate an HLS playlist (output.m3u8) along with a series of .ts files (video segments).

Step 3: Configure Nginx for Video Streaming

Next, you need to configure Nginx to serve your video files. Open the Nginx configuration file:

sudo nano /etc/nginx/nginx.conf

Add a new location block to serve your HLS files. For example:

http {
    ...
    server {
        listen       80;
        server_name  your_domain.com;

        location /videos/ {
            root /path/to/your/video/files/;  # Adjust the path
            add_header Cache-Control no-cache;
            add_header Access-Control-Allow-Origin *;  # Enable CORS for cross-domain access
        }
    }
}

Make sure to replace /path/to/your/video/files/ with the actual path where your video files are stored.

After updating the configuration, test it for syntax errors:

sudo nginx -t

If everything is fine, restart Nginx to apply the changes:

sudo systemctl restart nginx

Step 4: Embed JWPlayer on Your Website

Now that your server is set up for streaming, it’s time to embed JWPlayer into your website. First, sign up for a JWPlayer account and get your license key.

Use the following HTML code to embed the JWPlayer in your webpage:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Video Streaming with JWPlayer</title>
    <script src="https://cdn.jwplayer.com/libraries/your_jwplayer_key.js"></script>
</head>
<body>

    <div id="my-video"></div>
    <script>
        jwplayer("my-video").setup({
            file: "http://your_domain.com/videos/output.m3u8",  // Your HLS stream URL
            width: "640",
            height: "360"
        });
    </script>

</body>
</html>

Make sure to replace your_jwplayer_key with your actual JWPlayer key and http://your_domain.com/videos/output.m3u8 with the URL to your HLS playlist.

Step 5: Test Your Video Stream

Navigate to the webpage where you embedded JWPlayer. You should see the player load and be able to stream your video content. Test it on different devices and browsers to ensure compatibility.

Conclusion

Setting up video streaming with Nginx and JWPlayer on CentOS is a straightforward process that allows you to deliver high-quality video content to your audience. By following these steps, you can create a robust streaming service that meets your needs.
