title: How to determine if the guest web browser supports html5 <video>
body: <p>I am currently deploying a video platform. Videos are currently listed with the JWPlayer's plugin integration. I would like to set by default the <code>&lt;video&gt;</code> html5 tag, only if the guest's web browser supports it. How can I do to check if the .flv (encoded video format) is supported by the <code>&lt;video&gt;</code> tag of the guest's web browser ?</p>
  
  <p>Should I implement a javascript function ?</p>
