在WPF中使用VLC控制

谁能帮助我开始使用VLC控制在WPF应用程序?在我的项目中添加了引用，并在XAML

中创建了控件。XAML:

<Border Grid.Row="2" 
        Height="150" 
        Width="Auto" 
        Margin="10,0,10,0" 
        BorderThickness="1" 
        BorderBrush="Red" >
            <pl:VlcControl x:Name="Player" />
</Border>

后台代码

 public MainWindow()
 {
     InitializeComponent();
     Player.MediaPlayer.VlcLibDirectoryNeeded += OnVlcControlNeedsLibDirectory;
 }
 private void OnVlcControlNeedsLibDirectory(object sender, Vlc.DotNet.Forms.VlcLibDirectoryNeededEventArgs e)
 {
     var currentAssembly = Assembly.GetEntryAssembly();
     var currentDirectory = new FileInfo(currentAssembly.Location).DirectoryName;
     if (currentDirectory == null)
        return;
     if (AssemblyName.GetAssemblyName(currentAssembly.Location).ProcessorArchitecture == ProcessorArchitecture.X86)
        e.VlcLibDirectory = new DirectoryInfo(System.IO.Path.Combine(currentDirectory, @"vlslib'x86'"));
     else
        e.VlcLibDirectory = new DirectoryInfo(System.IO.Path.Combine(currentDirectory, @"vlslib'x64'"));
 }
 private void StartButton_Click(object sender, RoutedEventArgs e)
 {
     var d = new Microsoft.Win32.OpenFileDialog();
     d.Multiselect = false;
     if (d.ShowDialog() == true)
     {
        Uri src = new Uri(d.FileName);
        Player.Visibility = System.Windows.Visibility.Visible;
        Player.MediaPlayer.Play(src);
     }
 }

看起来不错，但是我看不到视频…我只听到视频里的声音，控制器什么也没显示…我做错了什么?

if (String.IsNullOrEmpty(Environment.GetEnvironmentVariable("PROCESSOR_ARCHITEW6432")))
{
    VlcContext.LibVlcDllsPath = CommonStrings.LIBVLC_DLLS_PATH_DEFAULT_VALUE_X86;
    //Set the vlc plugins directory path
    VlcContext.LibVlcPluginsPath = CommonStrings.PLUGINS_PATH_DEFAULT_VALUE_X86;
}
else
{
    VlcContext.LibVlcDllsPath = CommonStrings.LIBVLC_DLLS_PATH_DEFAULT_VALUE_AMD64;
    //Set the vlc plugins directory path
    VlcContext.LibVlcPluginsPath = CommonStrings.PLUGINS_PATH_DEFAULT_VALUE_AMD64;
}
