title: Phonegap/Cordova video record returning 3gp
body: <p>When I start recording video from my phonegap/cordova app, it's returning a 3gp on a Nexus 7 and Sony Xperia, but an mp4 on most other phones.</p>
  
  <p>It can't be an issue with the camera itself because if I record straight from the camera app, they both return mp4s.</p>
  
  <p>Is there a way to force it to always return mp4 within my app?</p>
