如何使用Vlc.DotNet在Windows Forms c#中流式传输RTSP摄像头源
如何使用Vlc.DotNet在Windows Forms c#中流式传输RTSP摄像头源
提问于 2018-05-18 21:15:32
我遵循了这个link的说明，将Vlc.DotNet库(.Core、.Core.Interops、.Forms和.Wpf)添加到我的项目解决方案中。
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，这就是生成的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;我在属性中添加了一个虚拟的VlcLibDirectory，这样我以后就可以修改它了。
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);
}
}RTSP变量返回一个类似于"rtsp://admin:admin123@190.19.191.19/Stream0“的m_stream.URL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的维基但我被卡住了。
我在这里做错了什么？

您所要做的就是向窗体中添加一个vlcControl，并向其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，您应该能够在Media->Open Network Stream...下的VLC应用程序上流式传输它
