Package Exports

node-hls-server

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (node-hls-server) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

node-hls-server

Simple HLS server running on NodeJS. It takes care of remuxing your video sources into HLS and serve it.

Features

Remux inputs (video or streaming) to HTTP Live Streaming (HLS)
Serve .m3u8 and .ts segments at a dedicated endpoint
Support for custom ffmpeg command options

Usage

Start the server

Default config

const HLSServer = require('hlsServer');
const server = new HLSServer(); // If no config is provided it will use the default options
server.run();

Custom Config

const HLSServer = require('hlsServer');
const server = new HLSServer({
    port: 8080,
    mediaPath: "./media",       // Root path to store media files
    cors: {                     // CORS options
        "Access-Control-Allow-Origin": "*",
        "Access-Control-Request-Method": "*",
        "Access-Control-Allow-Methods": "OPTIONS, GET",
        "Access-Control-Allow-Headers": "*" 
    }
    transOptions: [             // FFMPEG transcoding options
        "-c:v copy",
        "-c:a copy"
    ],
    hlsOptions: [               // Specific FFMPEG HLS options
        "-hls_wrap 5",
        "-hls_time 5"
    ],
    hlsFileName: "index.m3u8"   // m3u8 and segments basename
});  // See config options for more information
server.run();

Adding streams from sources

// addStream(streamName: String, streamSource: file path or URL)
server.addStream('stream1', 'path/to/video/file.mkv');
server.addStream('stream2', 'https://test-streams.mux.dev/x36xhzz/x36xhzz.m3u8')
server.addStream('stream3', 'http://clappr.io/highline.mp4')

Accessing streams

Once successfully added a stream, it will be served at:

localhost:{port}/{streamName}/{hslFileName}.m3u8

With default config and above examples, streams could be accesed at:

// M3U8 files
http://localhost:8080/stream1/index.m3u8 
http://localhost:8080/stream2/index.m3u8
http://localhost:8080/stream3/index.m3u8

// .ts segments files (just an example, several segments will be created and served from similar enpoints
http://localhost:8080/stream1/index1.ts 
http://localhost:8080/stream2/index1.ts
http://localhost:8080/stream3/index1.ts

TO DO

Improve logging

Contributing

This is my first open source project, feel free to report me errors, suggestions, anything you want.

Disclaimer

This project was inspired by node-media-server and hls-server projects. The first offers a lot of other features not related with HLS. The second is a very lightweigthed middleware that was not enought for my purposes. Both of them also include features for rtmp and other stuff I was not interested in.

They are very useful but I wanted to make my own project strictly dedicated for serving HLS streams.
