I tried MusicFile.play after setting up and starting the storyboard. Still the same problem.

The file is an mp3.

Thanks.

I will try the code out a little later, I think I moving the StoryBoard lines before the musicfile starts might be a good idea. Is this just a simple mp3 or wmv you are playing?

Hi, Thanks for the reply.

Set MaxFrameRate to 30, makes no difference.

No i'm not doing windowless="false" or have a html overlay

Any other ideas.

Thanks

Try lowering the MaxFrameRate setting in Silverlight to 30. The default is 60, this will make StoryBoards fire less events and consume less time in the main UI thread. This setting is set on the Silverlight control object.

Also are you doing Windowless="false" or any HTML overlay with Silverlight?

Music Playback v.choppy when timer is active (Silverlight 2)

Hi All,

Just trying to implement a basic music player with a progress bar.

I'm updating the progress bar using a timer/storyboard, checking the mediaelement progress. My problem is, when the storyboard is active, the music doesn't playback properly, as if it is cutting out when every time the timer fires. This is my vb code. TIA

     Dim sb As Storyboard

     Private Sub btnPlayPause_MouseLeftButtonUp(ByVal sender As System.Object, ByVal e As System.Windows.Input.MouseButtonEventArgs)

        If MusicFile.CurrentState <> MediaElementState.Playing Then

            MusicFile.Play()

            sb = New Storyboard
            sb.Duration = TimeSpan.FromMilliseconds(100)
            AddHandler sb.Completed, AddressOf Timer_Tick
            sb.Begin()


        ElseIf MusicFile.CurrentState = MediaElementState.Playing Then

            MusicFile.Pause()

            sb.Stop()
            sb = Nothing

        End If

    End Sub

    Private Sub Timer_Tick()

        MusicPos.Value = MusicFile.Position.TotalSeconds
        
        sb.Begin()


    End Sub
