Vlc.DotNet.Wpf录制视频

你可以使用Vlc.DotNet.Wpf库来录制视频，以下是一个基本的示例代码：

using System;
using System.Windows;
using Vlc.DotNet.Core;
using Vlc.DotNet.Core.Interops.Signatures.LibVlc.MediaPlayer;
using Vlc.DotNet.Wpf;

namespace VlcRecordingDemo
{
    public partial class MainWindow : Window
    {
        private VlcControl _vlcControl;
        private MediaPlayer _mediaPlayer;

        public MainWindow()
        {
            InitializeComponent();
            Loaded += MainWindow_Loaded;
        }

        private void MainWindow_Loaded(object sender, RoutedEventArgs e)
        {
            _vlcControl = new VlcControl();
            _vlcControl.MediaPlayer.VlcLibDirectory = new DirectoryInfo(@"C:\Program Files\VideoLAN\VLC");
            _vlcControl.MediaPlayer.EndReached += (s, args) => _mediaPlayer.Stop();
            _vlcControl.MediaPlayer.EncounteredError += (s, args) => MessageBox.Show("An error occurred.");
            _vlcControl.MediaPlayer.Log += (s, args) =>
            {
                if (args.Level <= VlcLogLevel.Warning)
                    Console.WriteLine(args.Message);
            };
            _mediaPlayer = _vlcControl.MediaPlayer;
            _mediaPlayer.SetMedia(new Uri("http://download.blender.org/peach/bigbuckbunny_movies/big_buck_bunny_480p_surround-fix.avi"));
            _vlcControl.Play();
            _mediaPlayer.Record("output.mp4");
        }

        protected override void OnClosed(EventArgs e)
        {
            base.OnClosed(e);
            _vlcControl.Dispose();
        }
    }
}

这个示例代码中，我们使用了VlcControl来播放一个网络视频，并将该视频录制到名为“output.mp4”的文件中。你需要注意的是，你需要将`_vlcControl.MediaPlayer.VlcLibDirectory`设置为你的VLC安装目录。
