MediaEnded event not firing

Question

 

I am playing mp3-files with a MediaElement and the MediaEnded event is not firing every time.
I found a post that it could happened if you try to play audio only files and have ScrubbingEnabled set to true so I set it to false but it still dose not fire the MediaEnded event.
It seems to happen randomly. I don´t find any logic in this.

Answer 1

I found out that the MediaElement never stops playing the sound. The duration just keeps on going and never stops to increase even thou the sound is very short (around one second)
Anyone know what to do???

Is there another way to play mp3 files. I have a clickonce application and I need to keep the trust level down as much as possible.

Answer 2

I cannot reproduce this problem, I use MediaPlayer to playback audio, if you don't play back video, you actually don't need to use MediaElement at all, here is my test code:

mediaPlayer = new MediaPlayer();
mediaPlayer.MediaEnded += delegate { MessageBox.Show("Media Ended"); };
mediaPlayer.Open(new Uri(@"C:\biyege.mp3"));
mediaPlayer.Play();

Thanks

I am having the same problem...

Currently I have 11 mediaelements inside borders in my WPF application. (Silverlight 2 beta with visual studio 2008 and expression blend 2.5 june preview)

 All of them start up just fine and also, loop fine for the first couple of times...then a random mediaelement will freeze up. I currently am looking for the mediaended event to repeat playback...

Here is my current code:
Note:the event handler for all of the Mediaelements is ME_11_MediaEnded, all mes are set to manual on load, and the scrubbing is disabled

.vb file

Imports System

Imports System.IO

Imports System.Net

Imports System.Windows

Imports System.Windows.Controls

Imports System.Windows.Data

Imports System.Windows.Media

Imports System.Windows.Media.Animation

Imports System.Windows.Navigation

Partial Public Class Window1

Private zerospan As New TimeSpan(0, 0, 0)

Public Sub New()

MyBase.New()

Try

Me.InitializeComponent()

' Insert code required on object creation below this point.

Catch ex As Exception

End Try

End Sub

Private Sub StartAllMEs()

ME_1A.Play()

ME_1B.Play()

ME_Cup.Play()

ME_L4.Play()

ME_L5.Play()

ME_L6.Play()

ME_L7.Play()

ME_L8.Play()

ME_L9.Play()

ME_L10.Play()

ME_L11.Play()

End Sub

Private Sub Window1_Loaded(ByVal sender As Object, ByVal e As System.Windows.RoutedEventArgs) Handles Me.Loaded

StartAllMEs()

End Sub

Private Sub ME_L11_MediaEnded(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs)

CType(sender, MediaElement).Position = zerospan

CType(sender, MediaElement).Play()

End Sub

End Class

I am also finding that the MediaEnded event is not being raised the way I expect it to. It is for me at least consistent though - if I create the MediaPlayer object in the same thread that owns the UI, it works. If I create the MediaPlayer object in a worker thread, it never raises the event or for that matter an exception to indicate a problem. I expect that restructuring the code to have the worker thread queue up media playback requests for the UI thread to actually trigger will be the only way to get the MediaEnded events to occur reliably.

Answer 6

Just in case someone reads this: The MediaPlayer events aren't fire probably because you don't have Dispatcher running in your worker thread.

Answer 7

How do I make sure Dispatcher is running ? I m instantiating a MEdiaElement object in the constructor and then

registering the event but it doesn't seem to get called.

BlankPage::BlankPage()
{
	InitializeComponent();

	MainSong = ref new MediaElement();
	MainSong->AutoPlay = false;
	MainSong->MediaEnded  += ref new RoutedEventHandler(this, &Application2::BlankPage::StateChangedEventHandler);
}
