c# - 如何使用 Vlc.DotNet 在 Windows Forms c# 中流式传输 RTSP 摄像头源

Question

我已经关注了这个 link添加 Vlc.DotNet 库(.Core、.Core.Interops、.Forms 和.Wpf) 添加到我项目的解决方案中。

我还添加了 3.0.0 版本的 VideoLAN.LibVLC.Windows 库。

我在表单中添加了一个 vlcControl，这是生成的 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;

我已经在属性中添加了一个虚拟的 VlcLibDirectory，以便以后可以更改它。

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

我尝试使用以下代码从 RTSP 流 url 获取视频源:

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 变量返回一个类似于“rtsp://admin:admin123@190.19.191.19/Stream0”的 RTSP 链接

我的表单出现了，但是我的 vlcController 没有显示任何东西......

我看了https://github.com/ZeBobo5/Vlc.DotNet的 wiki，但我卡住了...

我在这里做错了什么？

您所要做的就是将 vlcControl 添加到您的表单，并向其 VlcLibDirectoryNeeded 事件添加一些代码。

/// <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
}

如果流媒体链接正常，您应该可以在 Media->Open Network Stream... 下的 VLC 应用程序上流式传输它。
