VLC播放RTSP流媒体时延迟1到2秒

首先感谢  https://stackoverflow.com/questions/38326003/how-to-remove-a-delay-in-a-streaming-app        的说明

public Form1()
    {
        InitializeComponent();


        vlcControl1 = new Vlc.DotNet.Forms.VlcControl();

        this.vlcControl1.Location = new System.Drawing.Point(225, 65);
        this.vlcControl1.Name = "vlcControl1";
        this.vlcControl1.Size = new System.Drawing.Size(900, 700);
        this.vlcControl1.BackColor = System.Drawing.Color.Black;
        this.vlcControl1.Name = "vlcControl2";
        this.vlcControl1.Spu = -1;
        this.vlcControl1.TabIndex = 0;
        this.vlcControl1.Text = "vlcControl2";
        this.vlcControl1.VlcMediaplayerOptions = null;

        vlcControl1.VlcLibDirectory = new System.IO.DirectoryInfo(ConfigurationManager.AppSettings.Get("pathVLC64").ToString());

        this.Controls.Add(this.vlcControl1);

        ((System.ComponentModel.ISupportInitialize)(this.vlcControl1)).EndInit();

    }
 string uri = ConfigurationManager.AppSettings.Get("urlVideo").ToString();
string[] options = { ":network-caching=1000" };

        vlcControl1.Play(new Uri(uri), options);

就是用 vlcControl1.Play(new Uri(uri), options); 的方式打开。 

public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            tableLayoutPanel1.Dock = DockStyle.Fill;
        }

        bool isVedioOPen = false;
        private void button1_Click(object sender, EventArgs e)
        {
            if (!isVedioOPen)
            {
                isVedioOPen = true;
                button_vedio.Text = "关闭视频";
                //vlcControl1.Play(new Uri("http://download.blender.org/peach/bigbuckbunny_movies/big_buck_bunny_480p_surround-fix.avi"));
                //vlcControl1.Play(new Uri("rtsp://184.72.239.149/vod/mp4://BigBuckBunny_175k.mov"));
                
                string[] options = { ":network-caching=300" };
               
                vlcControl1.Play(new Uri("rtsp://184.72.239.149/vod/mp4://BigBuckBunny_175k.mov"), options);

            }
            else
            {
                isVedioOPen = false;
                button_vedio.Text = "打开视频";
                vlcControl1.Stop();
                vlcControl1.Refresh();
            }
        }

        private void vlcControl1_VlcLibDirectoryNeeded(object sender, Vlc.DotNet.Forms.VlcLibDirectoryNeededEventArgs e)
        {
            var currentAssembly = Assembly.GetEntryAssembly();
            var currentDirectory = new FileInfo(currentAssembly.Location).DirectoryName;
            if (currentDirectory == null)
                return;
            if (AssemblyName.GetAssemblyName(currentAssembly.Location).ProcessorArchitecture == ProcessorArchitecture.X86)
                e.VlcLibDirectory = new DirectoryInfo(Path.Combine(currentDirectory, @"libx86"));
            else
                e.VlcLibDirectory = new DirectoryInfo(Path.Combine(currentDirectory, @"libx64"));

            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);
                }
            }
        }

这个事件在这儿。然后在运行路径下，新建lib文件夹，分别支持x86和x64，

":network-caching=300"意思是延迟300毫秒，实际效果比之前延迟两秒好很多，肉眼感觉一秒钟没到，视频就跟着镜头和实物更新了。
