ThreadSeparatedImage quitts showing Video when removed and added back to VisualTree

[tinowild]

When I show the Video in a ThreadSeparatedImage I can't remove the ThreadSeparatedImage from the VisualTree, otherwise the Video isn't shown when I move it back again.

Example code (Press Clear to remove the ThreadSeparatedImage and Add to add it back again):

XAML

<Window x:Class="MetaVlcTest.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        mc:Ignorable="d"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition  Width="Auto"/>
            <ColumnDefinition />
        </Grid.ColumnDefinitions>
        <StackPanel Orientation="Vertical" Grid.Column="0">
            <Button Click="Button_Click_1">Clear</Button>
            <Button Click="Button_Click_2">Add</Button>
        </StackPanel>
        <Grid Grid.Column="1" Name="container"></Grid>
    </Grid>
</Window>

Code

using System;
using System.Windows;
using Meta.Vlc.Wpf;

namespace MetaVlcTest {
    /// <summary>
    /// Interaktionslogik für MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window {

        private VlcPlayer player;
        private ThreadSeparatedImage image;

        public MainWindow() {
            InitializeComponent();

            image = new ThreadSeparatedImage();
            container.Children.Add(image);

            player = new VlcPlayer(true);
            player.Initialize(@"..\..\LibVlc");
            player.LoadMedia(new Uri("rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov"));
            player.Play();

            image.Source = player.VideoSource;
            player.VideoSourceChanged += Player_VideoSourceChanged;
        }

        private void Player_VideoSourceChanged(object sender, VideoSourceChangedEventArgs e) {
            image.Source = e.NewVideoSource;
        }


        private void Button_Click_1(object sender, RoutedEventArgs e) {
            container.Children.Clear();
        }

        private void Button_Click_2(object sender, RoutedEventArgs e) {
            if (container.Children.Count == 0)
                container.Children.Add(image);
        }
    }
}

You need set the Source property again.

Setting image.Source = player.VideoSource; in Button_Click_2 after container.Children.Add(image); doesn't work for me. The only thing that worked is to replace the whole instance of the ThreadSeparatedImage.
