Question

我已按照此link的说明添加Vlc.DotNet个库（.Core，.Core.Interops，.Forms和.Wpf）我项目的解决方案。

我还添加了VideoLAN.LibVLC.Windows库的3.0.0版本。

我在表单中添加了一个vlcControl，结果是Designer.cs：

// 
// vlcControl1
// 
this.vlcControl1.BackColor = System.Drawing.Color.Black;
this.vlcControl1.Location = new System.Drawing.Point(384, 357);
this.vlcControl1.Name = "vlcControl1";
this.vlcControl1.Size = new System.Drawing.Size(75, 23);
this.vlcControl1.Spu = -1;
this.vlcControl1.TabIndex = 6;
this.vlcControl1.Text = "vlcControl1";
this.vlcControl1.VlcLibDirectory = ((System.IO.DirectoryInfo)(resources.GetObject("vlcControl1.VlcLibDirectory")));
this.vlcControl1.VlcMediaplayerOptions = null;

我在属性中添加了一个虚拟VlcLibDirectory，以便稍后更改。

我的vlcLib的x86版本的路径是：E:\testLouka\dansMaCamera2.0\dansMaCamera2.0\libvlc\win-x86

我尝试使用以下代码从RTSP流网址获取视频：

public partial class Form1 : Form
{
   public Form1()
   {
       InitializeComponent();

       this.vlcControl1 = new VlcControl()
       {
           Name = "vlc1",
           Location = new Point(0, 0),
           Dock = DockStyle.Fill,
           VlcLibDirectory = new DirectoryInfo(Path.Combine("E:\\testLouka\\dansMaCamera2.0\\dansMaCamera2.0", "libvlc", IntPtr.Size == 4 ? "win-x86" : "win-x64")),
           Spu = -1,
           VlcMediaplayerOptions = null,
           Enabled = true
       };
       string[] options = { ":network-caching=500" };

       vlcControl1.Play(new Uri(m_stream.URL), options);
   }
}

m_stream.URL变量返回的RTSP链接看起来像“rtsp://admin:admin123@190.19.191.19/Stream0”

我的表单显示，但我的vlcController没有显示任何内容......

我查看了https://github.com/ZeBobo5/Vlc.DotNet的wiki，但我被卡住了......

我在这里做错了什么？

您要做的就是在表单中添加一个vlcControl，并在其VlcLibDirectoryNeeded事件中添加一些代码。

/// <summary>
/// Looks for the vlc directory on the opening of the app
/// Opens a dialog if the libvlc folder is not found for the user to pick the good one
/// Folder for 32bits should be "libvlc\win-x86\" and "libvlc\win-x64\" for 64 bits
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void myVlcControl_VlcLibDirectoryNeeded(object sender, VlcLibDirectoryNeededEventArgs e)
{
    var currentAssembly = Assembly.GetEntryAssembly();
    var currentDirectory = new FileInfo(currentAssembly.Location).DirectoryName;

    if (currentDirectory == null)
        return;
    if (IntPtr.Size == 4)
        e.VlcLibDirectory = new DirectoryInfo(Path.GetFullPath(@".\libvlc\win-x86\"));
    else
        e.VlcLibDirectory = new DirectoryInfo(Path.GetFullPath(@".\libvlc\win-x64\"));

    if (!e.VlcLibDirectory.Exists)
    {
        var folderBrowserDialog = new System.Windows.Forms.FolderBrowserDialog();
        folderBrowserDialog.Description = "Select Vlc libraries folder.";
        folderBrowserDialog.RootFolder = Environment.SpecialFolder.Desktop;
        folderBrowserDialog.ShowNewFolderButton = true;
        if (folderBrowserDialog.ShowDialog() == DialogResult.OK)
        {
            e.VlcLibDirectory = new DirectoryInfo(folderBrowserDialog.SelectedPath);
        }
    }
}

然后，您可以在表单中添加某种播放按钮并播放任何想要的rtsp流！

private void btnPlay_Click(object sender, EventArgs e)
{
    myVlcControl.Play(MyStream.URL);//can test with rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115k.mov
}

如果流链接正常，您应该可以在Media->Open Network Stream...下的VLC应用上流式传输
