Convert mp4 or Avi to m3u8 in pure node js

I am searching a way to convert a mp4 or an .avi to .m3u8 in pure node js (firebase cloud function). Do you have ideas ?

Thank's, but I tried that :

const ffmpegInstaller = require('@ffmpeg-installer/ffmpeg');
const ffmpeg = require('fluent-ffmpeg');
ffmpeg.setFfmpegPath(ffmpegInstaller.path);
const ffmpeg_static = require('ffmpeg-static');
var cmd = ffmpeg('./flir_20191202T174341.mp4')
    .setFfmpegPath(ffmpeg_static.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);

And I have this error :

Error: Cannot find ffmpeg

Any ideas ?

Thanks in advance.

Found this answer: https://stackoverflow.com/a/42777596/8006046. It shows how you can run FFmpeg in the firebase cloud. You can replace 'path_or_readstream.mp4' with either the path to the file you want to convert, or, which is more probable in a cloud function, you could pass the readable stream with the file you want to convert.

const ffmpeg = require('fluent-ffmpeg');
const ffmpeg_static = require('ffmpeg-static');

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