播放带有音频的视频黑屏(Vlc.DotNet和libvlcsharp)

Question

我有一个简单的WinForms解决方案，有两个视频播放器，一个是Vlc.DotNet，另一个是利布利普。

除此之外，我还有一个简单的按钮，可以播放两个视频。

对于libvlcsharp，我遵循了这的示例

对于Vlc.DotNet，我使用了这示例

此外，im还附加了logFiles Loglibvlcsharp.txt和LogVlcDotNet。

这是我的密码

public partial class QueueDisplayVideoView : Form
{
    private string[] paths, files;
    private int videoIndex = 0;

    public LibVLC _libVLC;
    public MediaPlayer _mp;
    public LibVLCSharp.Shared.Media media;

    public QueueDisplayVideoView()
    {
        InitializeComponent();
        Core.Initialize();
        _libVLC = new LibVLC(enableDebugLogs:true);
        _libVLC.SetLogFile(@"C:\Temp\LogLib.txt");
        _mp = new MediaPlayer(_libVLC);
        videoView.MediaPlayer = _mp;

    }


    protected override void OnLoad(EventArgs e)
    {           
        _presenter.OnViewReady();
        base.OnLoad(e);

        LoadVideoFiles();
        SetPlayerAspectRatio();
        //StartAutoPlay();
    }

    private void StartAutoPlay()
    {
        vlcControl.Play(new Uri(paths[videoIndex]));
        _mp.Play(new LibVLCSharp.Shared.Media(_libVLC, new Uri(paths[videoIndex])));
    }

    private void LoadVideoFiles()
    {     
        var path = some path
        paths = Directory.GetFiles(path, "*", SearchOption.AllDirectories);
        files = new string[paths.Length];
        for (int i = 0; i < paths.Length; i++)
        {
            files[i] = Path.GetFileName(paths[i]);
        }
    
    }

    private void SetPlayerAspectRatio()
    {
        var videoWidth = vlcControl.Width.ToString();
        var videoHieght = vlcControl.Height.ToString();
        vlcControl.Video.AspectRatio = videoWidth + ":" + videoHieght;
    }

    private void vlcControl_VlcLibDirectoryNeeded(object sender, Vlc.DotNet.Forms.VlcLibDirectoryNeededEventArgs e)
    {
        // var currentAssembly = System.Reflection.Assembly.GetEntryAssembly();
        var currentDirectory = @"Q:\bin";  //new FileInfo(currentAssembly.Location).DirectoryName;
        // Default installation path of VideoLAN.LibVLC.Windows
        var fullPath = Path.Combine(currentDirectory, "libvlc", IntPtr.Size == 4 ? "win-x86" : "win-x64");
        e.VlcLibDirectory =  new DirectoryInfo(fullPath);
    }


    private void vlcControl_EndReached(object sender, Vlc.DotNet.Core.VlcMediaPlayerEndReachedEventArgs e)
    {
        GetNextVideoIndex();
        ThreadPool.QueueUserWorkItem(_ => vlcControl.Play(new Uri(paths[videoIndex])));
    }

    private void button1_Click(object sender, EventArgs e)
    {
        StartAutoPlay();
    }

    private void GetNextVideoIndex()
    {
        if (videoIndex < files.Length - 1)
        {
            videoIndex = videoIndex + 1;
        }
        else
        {
            videoIndex = 0;
        }
    }
}

你试过使用这吗？

它应该是winforms的本机，

您只需在工具箱中选择正确的.dll ->> com组合-> windows媒体播放器.
