title: HTML 5 Video seek/chapters
body: <p>I've got a long .m4v video file (~ 1 hour) on my server,but I want to show a video on my site (HTML-5 ) that only show's subsections of it (e.g minutes 3 -> 5 followed by minutes 19 -> 20). So the video my users see is only 5 mins long. </p>
  
  <p>Is anyone aware of any current HTML-5 video players or clever tricks that would support this use case ? I guess the functionality I want is like the quicktime reference file, but in HTML5 -video so that if my users play the video through they only see the 'sub-sections' and nothing in between.</p>
  
  <p>Any help appreciated.</p>
