getting video length of mov file with no audio error chrome js

Question

Is there an accurate way to determine the length of a .mov file with chrome? On our website we currently use video.onloadedmetadata but it's causing errors.

Example:

upload(data) {
 const file = data.body.get('file');
 const filename = file.name;

 const video = document.createElement('video');
 video.preload = 'metadata';
 video.onloadedmetadata = () => {
   const videoDuration = Math.floor(video.duration);
 }

 video.onerror = (error) => {
   debugger;
   console.error(error);
 };
};
