hls-stream-creator

HLS Stream Creator - Node.js

Create an M3U8 playlist from media file using FFMPEG.

Installation

npm i hls-stream-creator

Prerequisites

This package using fluent-ffmpeg so ffmpeg must be installed it requires at least ffmpeg 0.9 to work.

You must also have ffprobe installed (it comes with ffmpeg in most distributions).

Windows users: most probably ffmpeg and ffprobe will not be in your %PATH, so you must set %FFMPEG_PATH and %FFPROBE_PATH.

Debian/Ubuntu users: the official repositories have the ffmpeg/ffprobe executable in the libav-tools package, and they are actually rebranded avconv/avprobe executables (avconv is a fork of ffmpeg). They should be mostly compatible, but should you encounter any issue, you may want to use the real ffmpeg instead. You can either compile it from source or find a pre-built .deb package at https://ffmpeg.org/download.html (For Ubuntu, the ppa:mc3man/trusty-media PPA provides recent builds).

Usage

const hlsStreamCreator = require('hls-stream-creator');

(async () => {
  const settings = {
    renditions: [
      {

          height: 1080,
        },
