Vlc.DotNet如何在Wpf中打开视频并显示第一帧？

VlcContext.LibVlcDllsPath = @"C:\Program Files\VideoLAN\VLC";
VlcContext.LibVlcPluginsPath = @"C:\Program Files\VideoLAN\VLC\plugins";
VlcContext.StartupOptions.IgnoreConfig = true;
VlcContext.StartupOptions.LogOptions.LogInFile = false;
VlcContext.StartupOptions.LogOptions.ShowLoggerConsole = false;
VlcContext.StartupOptions.LogOptions.Verbosity = VlcLogVerbosities.None;
VlcContext.Initialize();

var mediaPlayer = new Vlc.DotNet.Forms.VlcControl();
videoControl.Children.Add(mediaPlayer);

mediaPlayer.SourceProvider.CreatePlayer(new DirectoryInfo(@"C:\Path\To\Video\File"));
mediaPlayer.SourceProvider.MediaPlayer.Play();

mediaPlayer.Playing += (sender, args) =>
{
    mediaPlayer.TakeSnapshot();
    mediaPlayer.Stop();
};

mediaPlayer.SnapshotTaken += (sender, args) =>
{
    string imagePath = @"C:\Path\To\Save\Snapshot\Image.jpg";
    args.Snapshot.Save(imagePath, ImageFormat.Jpeg);
    // 将imagePath绑定到Image控件的Source属性上
};
