title: Html5 video poster has a delay
body: <p>i'm working with html5 video and noticed that, when a video ends(firing the ended event), the last image of the video is freezed for a sec or so, before showing me the poster image.</p>
  
  <p>Has html5 video tag any attribute for this? Cos i want my poster to be shown right after the video ends.</p>
  
  <p>Thanks</p>
