How to upload video in Quill Editor?

Question

Currently, we are able to upload image using Quill Editor. which is base64 but we can upload that usign image handler. like this below:

modules: {
    toolbar: {
      container: '#toolbar',
      handlers: {
        'image': imageHandler
      }
    }
  },

the offical image handler is here:

function () {
  let fileInput = this.container.querySelector('input.ql-image[type=file]');
  if (fileInput == null) {
    fileInput = document.createElement('input');
    fileInput.setAttribute('type', 'file');
    fileInput.setAttribute('accept', 'image/png, image/gif, image/jpeg, image/bmp, image/x-icon');
    fileInput.classList.add('ql-image');
    fileInput.addEventListener('change', () => {
      if (fileInput.files != null && fileInput.files[0] != null) {
        let reader = new FileReader();
        reader.onload = (e) => {
          let range = this.quill.getSelection(true);
          this.quill.updateContents(new Delta()
            .retain(range.index)
            .delete(range.length)
            .insert({ image: e.target.result })
          , Emitter.sources.USER);
          fileInput.value = "";
        }
        reader.readAsDataURL(fileInput.files[0]);
      }
    });
    this.container.appendChild(fileInput);
  }
  fileInput.click();
}

My question is how to upload video instead?
