Question

I am currently working on an MP3 player (in a WPF application) with a WPF MediaPlayer and basically, I want to implement a Song Seeker which moves along with th

Answer 1

Never played with media player but assuming you know the length of song could you not setup a timer that ticks every second while the song is playing. Therefore for every tick just increment the seeker in relation to how long the song is in total.

Song is 100 seconds long. Therefore every second/tick is worth 1 percent of total progress.

You'd have to stop the timer when pausing song etc...

Answer 2

Have you checked out the WPF MediaKit yet?

ARISE answer! and serve your master

OK, I've figured out how to work this. I'm sure I'm not doing it the completely correct way but it does work.

Here is the code-behind of a WPF application, with a Pause/Play button.

public partial class Main : Window
{
    MediaPlayer MPlayer;
    MediaTimeline MTimeline;

    public Main()
    {
        InitializeComponent();

        var uri = new Uri("C:\\Test.mp3");
        MPlayer = new MediaPlayer();
        MTimeline = new MediaTimeline(uri);
        MTimeline.CurrentTimeInvalidated += new EventHandler(MTimeline_CurrentTimeInvalidated);
        MPlayer.Clock = MTimeline.CreateClock(true) as MediaClock;
        MPlayer.Clock.Controller.Stop();
    }

    void MTimeline_CurrentTimeInvalidated(object sender, EventArgs e)
    {
        Console.WriteLine(MPlayer.Clock.CurrentTime.Value.TotalSeconds);
    }

    private void btnPlayPause_Click(object sender, RoutedEventArgs e)
    {
        //Is Active
        if (MPlayer.Clock.CurrentState == ClockState.Active)
        {
            //Is Paused
            if (MPlayer.Clock.CurrentGlobalSpeed == 0.0)
                MPlayer.Clock.Controller.Resume();
            else //Is Playing
                MPlayer.Clock.Controller.Pause();
        }
        else if (MPlayer.Clock.CurrentState == ClockState.Stopped) //Is Stopped
            MPlayer.Clock.Controller.Begin();
    }
}

The trick is that once you set the clock of a MediaPlayer, it becomes clock controlled, thus the use of MPlayer.Clock.Controller to do all of the controlling :)

MediaElement has a position property which you could use for this: http://msdn.microsoft.com/en-us/library/system.windows.controls.mediaelement.position.aspx
