Silverlight播放器 一

引入命名空间 Microsoft.Web.Media.SmoothStreaming

该DLL下可以使用播放器控件ssme，直接支持平滑播放。SMF播放器（PPPMF）也是以ssme为核心的播放器。

插入播放器页面代码

<div id="silverlightControlHost">
        <object data="data:application/x-silverlight-2," type="application/x-silverlight-2"
            width="480" height="400">

                <img src="http://go.microsoft.com/fwlink/?LinkID=161376" alt="获取 Microsoft Silverlight"
                    style="border-style: none" />
            </a>
        </object>
        <iframe id='_sl_historyFrame' style='visibility: hidden; height: 0; width: 0; border: 0px'>
        </iframe>
    </div>

silverlight中接受传入参数InitParams代码

public static string mediaurl;

private void Application_Startup(object sender, StartupEventArgs e)
  {
            _dic = e.InitParams;
            mediaurl = e.InitParams["broadcastUrl"].ToString().Trim();
            this.RootVisual = new MainPage(_dic);
  }

后台指定直播点

 public MainPage(IDictionary<string, string> dicParam)
        {

            InitializeComponent();//该句应该放在该函数里第一行，否则报错

            _isNavigator = HtmlPage.BrowserInformation.Name.Contains("Netscape");
            
            //dicParam.TryGetValue("broadcastUrl", out  PlayUri);
            Me.SmoothStreamingSource = new Uri(App.mediaurl);
            label1.Content = PlayUri.ToString();
            // 为初始化变量所必需
            C.Width = player_width;
            C.Height = player_height + 40;
            Me.Width = player_width;
            Me.Height = player_height;
            StackControl.Width = player_width;
            label1.Content = ie_width.ToString() + ":" + ie_height.ToString();

            Application.Current.Host.Content.FullScreenChanged += new EventHandler(Content_FullScreenChanged);

            //Me.PlaybackTrackChanged += new EventHandler<Microsoft.Web.Media.SmoothStreaming.TrackChangedEventArgs>(Me_PlaybackTrackChanged);
