Detect if video was completed?

[Rick Harrison]

I have an HTML5/Javascript video player that
plays a video and displays the video duration 
and current play time, using LiveCode Server.  

I want to know when the current time 
equals the duration time so I can then invoke a
LiveCode process that makes a note that
the video was fully played so I can unlock
another webpage to be viewed.

I think I need a way to get the current time
and video duration values of the javascript
into LiveCode variables.

Any ideas how I could do this?

Thanks,

Rick
