Error when converting mp4 video to HLS using stream as input in node js using ffmpeg

Question

I am trying to convert an MP4 file to HLS using ffmpeg. Code:

var stream = createReadStream(filePath);
ffmpeg(stream)
    .on('stderr', function(stderrLine) {
        console.log('Stderr output: ' + stderrLine);
    })
    .on('end', function() {
        console.log('done processing input stream');
    })
    .on('error', function(err) {
        console.log('an error happened: ' + err.message);
    })
    .save(join(__basedir, "public", `file.m3u8`));

OutPut:

I've also tried with moveflag option .outputOptions("-movflags isml+frag_keyframe") also with -movflags faststart

I've read through How do you use Node.js to stream an MP4 file with ffmpeg?

But i didn't quite understand what and how to do it.

To achieve HLS from mp4 video we can use the below code.

We will pass the video as input with ffmpeg tags options. In this example, I am converting a 480p resolution related playlist. we can use the same code by just updating resolutions for 720p and 360p
after creating all three resolutions we will add MASTER PLAYLIST which contains all three versions with different BANDWIDTH options. this bandwidth will switch videos versions automatically based on your internet speed.

MASTER_PLAYLIST_SAMPLE

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-STREAM-INF:BANDWIDTH=800000,RESOLUTION=640x360
https://PROJECT_PATH/hls/5001/101/hlsThumbs/360/sample_video_360.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=1400000,RESOLUTION=842x480
https://PROJECT_PATH/hls/5001/101/hlsThumbs/480/sample_video_480.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=2800000,RESOLUTION=1280x720
https://PROJECT_PATH/hls/5001/101/hlsThumbs/720/sample_video_720.m3u8
#EXT-X-ENDLIST

VERSIONING_FILE_SAMPLE

let ffmpegPath = require('@ffmpeg-installer/ffmpeg').path;
let ffmpeg = require('fluent-ffmpeg');
ffmpeg.setFfmpegPath(ffmpegPath);

const creatorId = 5001;
const videoId = 101;
const videoFileName = "sample_video.mp4";
const version480Name = "sample_video_480.m3u8"

ffmpeg('public/assets/hls/'+creatorId+'/'+videoId+'/original/'+videoFileName, { timeout: 432000 }).addOptions([
  '-strict -2',
  '-preset:v veryfast', 
  '-profile:v baseline', // baseline profile (level 3.0) for H264 video codec
  '-level 3.0', 
  '-s 842x480',          // 842px width, 480px height output video dimensions
  '-start_number 0',     // start the first .ts segment at index 0
  '-hls_time 10',        // 10 second segment duration
  '-hls_list_size 0',    // Maxmimum number of playlist entries (0 means all entries/infinite)
  '-f hls'               // HLS format
]).output('public/assets/hls/'+creatorId+'/'+videoId+'/hlsThumbs/480/'+version480Name)
.on('error', function(err, stdout, stderr) {
console.log('An error occurred: ' + err);
console.log("ffmpeg stdout:\n" + stdout);
console.log("ffmpeg stderr:\n" + stderr);
console.log("Hls Cannot be converted for this video");
callback(err);
})
.on('progress', function(progress) { 
  console.log('HLS Processing : 480p ----'+ JSON.stringify(progress) + ' done'); })
.on('end', callback1).run();
