FFmpeg node js convert video file (.mp4) to m3u8 : Output format m3u8 is not available

Question

I want to convert videos files (like .mp4 or .avi) to .m3u8 in nodeJs. I tried to do that with ffmpeg and node-js, but that don't work : 'Output format m3u8 is not available'.

Here is my nodeJs code :

const ffmpegInstaller = require('@ffmpeg-installer/ffmpeg');
const ffmpeg = require('fluent-ffmpeg');

var cmd = ffmpeg('./flir_20191202T174341.mp4')
    .setFfmpegPath(ffmpegInstaller.path)
    .videoBitrate(1024)
    .videoCodec('divx')
    .format('m3u8')
    .on('end', () => {
        // ...
    })
    .on('error', err => {
        console.error(err);
    })
    .save('./file-out.m3u8');
console.log('Hello !');
console.log(cmd);

Do you know how can I do that correctly ?

Thank's in advance.

I found the solution :

var fs = require('fs');
var ffmpeg = require('fluent-ffmpeg');

// open input stream
var infs = new ffmpeg

infs.addInput('video.mp4').outputOptions([
    '-map 0:0',
    '-map 0:1',
    '-map 0:0',
    '-map 0:1',
    '-s:v:0 2160x3840',
    '-c:v:0 libx264',
    '-b:v:0 2000k',
    '-s:v:1 960x540',
    '-c:v:1 libx264',
    '-b:v:1 365k',
    // '-var_stream_map', '"v:0,a:0 v:1,a:1"',
    '-master_pl_name master.m3u8',
    '-f hls',
    '-max_muxing_queue_size 1024',
    '-hls_time 1',
    '-hls_list_size 0',
    '-hls_segment_filename', 'v%v/fileSequence%d.ts'
]).output('./video.m3u8')
    .on('start', function (commandLine) {
        console.log('Spawned Ffmpeg with command: ' + commandLine);
    })
    .on('error', function (err, stdout, stderr) {
        console.log('An error occurred: ' + err.message, err, stderr);
    })
    .on('progress', function (progress) {
        console.log('Processing: ' + progress.percent + '% done')
    })
    .on('end', function (err, stdout, stderr) {
        console.log('Finished processing!' /*, err, stdout, stderr*/)
    })
    .run()
