title: Change the MIME type in WordPress
body: <p>I am using JW Player plugin from wordpress. I try to upload mp4 file in the admin dashboard -> media 
  There is nothing problem in the uploading. but when i try to load the video in jw player of wordpress it loads only audio. When i try to upload the file it shows the mime type as 
  video/quicktime but i uploaded the mp4 file and mime type should be video/mp4 Not sure why this should happen.</p>
