如何使用Vlc在Windows窗体c#中流式传输RTSP相机馈送。点网

onvif libvlc rtsp winforms c#

LoukMouk · 技术社区 · 6 年前

我跟踪了这个 link 的指示添加 Vlc.DotNet 图书馆( .Core ,则, .Core.Interops ,则, .Forms 和 .Wpf )我的项目解决方案。

我还添加了 VideoLAN.LibVLC.Windows 图书馆

我在表单中添加了一个vlcControl,这就是结果 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,以便以后更改它。

我的vlcLib 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url获取视频提要:

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);
   }
}

这个 m_stream.URL 变量正在返回RTSP链接,如下所示“ rtsp://admin:admin123@190.19.191.19/Stream0 “”

我的表单出现了,但我的vlcController没有显示任何内容。。。

我看着 https://github.com/ZeBobo5/Vlc.DotNet 的wiki,但我被卡住了。。。

我做错了什么?

您只需添加一个 vlcControl 并向其添加一些代码 VlcLibDirectoryNeeded 事件

/// <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类型的播放按钮,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,您应该能够在VLC应用程序上的 Media->Open Network Stream...
