Find Video Duration From Content-Length in NodeJS

Is there any way to calculate the video duration in a millisecond from content-length?

request
  .get("http://myvideourl.com/filename.mp4")
  .on("response", response => {
    const content_length = response.headers.content-length;// "content-length": "1986943971"
    res.json({
      stream_duration: "",
      thumb: thumb,
      size: content_length,
    });
  });

Note : Video Format is MP4 , res is express object, request is a httpclient library in NodeJS

You can use this npm module It will help you to get the video length even from an url

const { getVideoDurationInSeconds } = require('get-video-duration');
getVideoDurationInSeconds('http://myvideourl.com/filename.mp4').then((duration) => {
    console.log(duration)
}) 

Of course you can then convert it into milliseconds. (x1000).
