how to get video stop time in asp.net?

Hi All,
I want to play video in asp.net web forms.
for that i am using video tag in html5.
now i want to get the video stop time.
I mean i have button called stop and a label control.
now when video is playing i will click stop button then i want to stop the video and get the video stopped time  and displays on label.

for example video contains 5 mins duration,now video playing at 2.30 mins position, now if i click the stop button i want to display 2.30 mins on label.
how can i do that?


Thanks,
Murali.
