c# WPF how to repeat MediaElement playback from mediaended event handler without declaring new source?

Question

I'm playing a video in WPF.i want it to loop so what I did is when the mediaended event fires, I play back my video. so this will get me a loop. prob is why do u I have to create new source again? why can't I just call 'play'?

I don't want to do it in XAML as for some reason.

have a look at my code snippet:

string startPath System.IO.Path.GetDirectoryName(Process.GetCurrentProcess().MainModule.FileName);


public Window1()
    {
        InitializeComponent();
        media.Source = new Uri(startPath + @"playlist.wpl");
        media.play();
    }

private void Media_Ended(object sender, EventArgs e)
    {
        media.Source = new Uri(startPath + @"playlist.wpl"); //if i dont put this line, video wont play..seems like it cant get the source
        media.Play();
    }

or is there a proper way to loop NOT in XAML but in here .cs file?

Instead of resetting the Source at the start of your Media_Ended handler, try setting the Position value back to the start position. The Position property is a TimeSpan so you probably want something like...

private void Media_Ended(object sender, EventArgs e)
{
    media.Position = TimeSpan.Zero;
    media.Play();
}

thnx for your answer. i've tried this earlier but no success.video doesnt play back. – Psychocryo May 12 '11 at 09:32
Hmmm...that's strange. I tested it, but with an audio file not a video. Not sure why video would be different - I'll take another look. – IanR May 12 '11 at 09:36

You don't even need to set LoadedBehavior as Manual just leave it Play.

And reset your media position on MediaEnded.

The new position of the video should be greater than zero:

private void MediaElement_MediaEnded(object sender, RoutedEventArgs e)
{
     media.Position = TimeSpan.FromMilliseconds(1);
}

I make it work setting the UnloadedBehavior="Manual" and the follwing code

 private void gifAnimation_MediaEnded(object sender, RoutedEventArgs e)
 {
    gifAnimation.Position = new TimeSpan(0,0,1);
    gifAnimation.Play();
 }

Setting the position to Zero didnt work...

I think you should use this code :

private void Media_Ended(object sender, EventArgs e)
{
   media.Position = TimeSpan.Zero;
   media.LoadedBehavior = MediaState.Play;
}

I hope this will help.

Please don't provide "code only" answers. Why do you think this is the answer? – Lee Taylor Nov 17 '12 at 00:05

This worked for me, you can't call "Play" if the LoadBehaviour has already been set to Play in the XAML. – Mark Feldman Jan 14 '15 at 00:08

~~You don't have to set the source again.Just set the position of the mediaelement to the start on the media_ended event~~

 private void MediaElement_MediaEnded(object sender, RoutedEventArgs e)
        {
            ((MediaElement)(sender)).Stop();
            ((MediaElement)(sender)).Position = new TimeSpan(0, 0, 0);
            ((MediaElement)(sender)).Play();
        }

You may need to set MediaElement.LoadedBehavior to Manual

EDIT

I have tried loading an asf file with the REPEAT tag and its working fine

<ASX version = "3.0">
   <TITLE>Simple ASX Demo</TITLE>
<REPEAT> 
      <ENTRY>
         <TITLE>Vista Butterfly Video</TITLE>
         <AUTHOR>Microsoft Corporation</AUTHOR>
         <COPYRIGHT>(c)2007 Microsoft Corporation</COPYRIGHT>
         <REF HREF = "Butterfly.wmv" />
     </ENTRY>
</REPEAT> 
</ASX>

But i think the inbuilt playlist handling mechanism of mediaelement has some flaws.I recommend following the workaround mentioned in the below link

it seems that it's working if the media is a single file but not working if i use a playlist file such as .wpl or .asx file format. any clue? – Psychocryo May 16 '11 at 06:45
So after the entire playlist is finished...you want to repeat from the first file right ? – biju May 16 '11 at 07:11
Also how do you manage your playlist ? AFIK The MediaElement does not have a built in playlist handling mechanism. – biju May 16 '11 at 07:24
yeah.i want to play all from the beginning.so i did all the same as your instruction but the media source is a .wpl file. i tried an .asx file but the same result.it doesnt repeat back. if i use media source such as lexus.mp4, everything goes fine using ur instruction..any idea? – Psychocryo May 16 '11 at 07:41
@biju,thnx mate.i'll give it a go and see how.thnx again. – Psychocryo May 19 '11 at 12:53
