Here is the answer !!
Let support your video tag is like this --
< video id="video_source" src="sound.ogg">
Your browser does not support the
in javscript you can do lot of stuff like
var video = document.getElementById("video_source");
video.play(); //for play
video.pause(); //for pause
var curr_time = video.currentTime ;// this will give a seek bar time, Or simply elapsed time
//for restarting the video
video.currentTime = 0;
I am also trying to play with controlling other parameters like volume and other things !! Say Tuned !!
