I have created a FLV player with Play, Start, End and Stop Buttons.

Where start is starting point and end is ending point. After Assigning these both points ,play the video u will just have that much duration video.
The Progress Bar Progressively increasing with the video.

Now when i press start button. i need to show a point on Progress Bar or need to change color of Progress Bar when Start Point assigned. so user can know this is start point .

same with the end point .

Please have look on this query

Thanks in Advance
