Allow input of all types of video files

Currenty my website doesn't allow input of .avi, .wmv etc. files and doesn't process it.

The code looks like this -

<input
  type="file"
  id="previewVideo"
  style=
  accept="video/mp4,video/x-m4v,video/*"
/>

I want it to accept all types of video files. How can I do that? Thanks in advance.
