Bind mediaelement to viewmodel

Question

I´m working on a big project in wpf that uses Caliburn Micro. I have done a view that should view a movie. I´m trying to bind MediaElement Source to my file that I have in my ViewModel.

My View looks like this:

<TreeView.ItemTemplate>
            <HierarchicalDataTemplate ItemsSource="{Binding Items}">
                <ContentControl cb:View.Model="{Binding}" />
            </HierarchicalDataTemplate>
        </TreeView.ItemTemplate>
    </controls:ExtendedTreeView>
    <MediaElement Source="media" Visibility="{Binding IsIndexVisible, Converter={StaticResource InvertBoolToHiddenConverter}}" />

And in my viewmodel:

  public override void NavigateEnter()
    {
        //base.NavigateEnter();

        if (CanExpand)
        {
            base.Expand();
            return;
        }

        if (SelectedItem == null) return;

            var media = new MediaElement();

            media.LoadedBehavior = MediaState.Manual;
            media.Source = new Uri(@"C:/Users/v80770/Desktop/Movies/ATTV_bog.mpg");
            media.Play();
     }

            private Uri _mediaUri;
        public Uri MediaUri
        {
            get
            {
                return _mediaUri;
            }
            set
            {
                _mediaUri = value;
                NotifyOfPropertyChange(() => MediaUri);
            }
        }

  public override void NavigateEnter()
        {
            //base.NavigateEnter();

            if (CanExpand)
            {
                base.Expand();
                return;
            }

            if (SelectedItem == null) return;

            var test = (@"C:/Users/v80770/Desktop/Movies/ATTV_bog.mpg");
            var mediauri = new Uri(test);
            _mediaUri = mediauri;

            IsIndexVisible = false;
        }

But when I start my project nothing shows at all.

You need to bind the Uri as Source for Media Element. The Source Dependency Property expects type of Uri. You can verify it here.

<MediaElement Source="{Binding MediaUri}" />

Where MediaUri is defined as

public Uri MediaUri {get;set; }
