I have made a WPF Media Player that has SeekBar. I have following code to seek to different position. This code has been written under Slider.ValueChanged event.

mePlayerMain.Position = TimeSpan.FromSeconds(sliderSeekBar.Value);

I have also timer control to control the progress of the seek bar in each tick. I have written following code in MediaElement.MediaOpened

if (mePlayerMain.NaturalDuration.HasTimeSpan)
            {
                TimeSpan ts = new TimeSpan();
                ts = mePlayerMain.NaturalDuration.TimeSpan;
                sliderSeekBar.Maximum = ts.TotalSeconds;
                sliderSeekBar.SmallChange = 1;
            }
            timer.Start();

and for each timer tick, I update the seekbar position

sliderSeekBar.Value = mePlayerMain.Position.TotalSeconds;

But my problem is whenever a media file is playing on the player, media file is disrupted for few seconds and then it plays again. Everythings fine but media file is not smoothly played. Please help me.

You are almost there.

The problem is that everytime the timer ticks you update the slider value, which causes your slider value changed handler to fire, which sets the position on the video, causing it to skip.

Use a variable to suppress the code in the slider value changed handler before you update your slider value in the tick handler, like so:

C#

bool suppressMediaPositionUpdate = false;

void TimerTickHandler(object sender, EventArgs e)
{
   suppressMediaPositionUpdate = true;
   sliderSeekBar.Value = mePlayerMain.Position.TotalSeconds;
}


void SliderValueChangedHandler(object sender, EventArgs e)
{
   if(suppressMediaPositionUpdate)
   {   
      suppressMediaPositionUpdate = false;
   }
   else
   {
      mePlayerMain.Position = TimeSpan.FromSeconds(sliderSeekBar.Value);
   }
}
