Seekbar

#Seekbar

I have created a couple of slides and added video in one of it. 

In the slides, though the content(audio, infographics) finished at certain points, the seek bar continue to progress.

Where can i control the seekbar along with the time?

example: My audio and graphics files finishes the action in exactly at 15 seconds, then the seek bar progress must also complete by 15 seconds. Where as in my file it continues for long time (Though i turn showtillend button disable for all my elements.)
