編碼器SDK 4 - 推送到發佈點

我正在使用EC4 SP2 SDK在c＃中編寫應用程序。編碼器SDK 4 - 推送到發佈點

我想將我的文件發佈到媒體服務器發佈點。我搜索了2個關於發佈點的驗證和認證的例子，但是它們都來自舊的sdk's或者不工作（並且用於控制檯）。基本上我的應用程序不編碼任何東西，就好像它沒有任何編碼。當在消除模式checkpont我可以看到源文件和服務器的正確屬性。

編碼過程需要0secs來處理。我檢查了服務器事件上的日誌，並收到警告「安全系統已收到並且無法解碼的身份驗證請求」。我只是沒有什麼知識可以比這個更進一步。任何幫助，將不勝感激。

這是一段代碼：

private void broadcastSourceFileToMediaServer2() 
    {    
     using (LiveJob job = new LiveJob()) 
     { 
      String filetoencode = @"c:\temp\niceday.wmv"; 

      LiveFileSource filesource = job.AddFileSource(filetoencode); 
      filesource.PlaybackMode = FileSourcePlaybackMode.Loop; 
      job.ActivateSource(filesource); 
      job.ApplyPreset(LivePresets.VC1Broadband4x3); 

      //don't know which one is good to use 
      job.AcquireCredentials += new EventHandler<AcquireCredentialsEventArgs>(job_AcquireCredentials); 
      _myUserName = "indes"; 
      _pw = PullPW("indes");    

      Uri url = new Uri("http://192.168.1.74:8080/live"); 
      PushBroadcastPublishFormat pubpoint = new PushBroadcastPublishFormat(); 
      pubpoint.PublishingPoint = url; 

      pubpoint.UserName = _myUserName; 
      pubpoint.Password = _pw; 

      job.PublishFormats.Add(pubpoint);  

      job.PreConnectPublishingPoint(); 

      job.StartEncoding(); 
      statusBox.Text = job.NumberOfEncodedSamples.ToString(); 

      job.StopEncoding(); 
      job.Dispose(); 
     } 
    } 




    public static string _myUserName { get; set; } 

    public static SecureString _pw { get; set; } 

    //codificação de Password a enviar 
    private static SecureString PullPW(string pw) 
    { 
     SecureString s = new SecureString(); 
     foreach (char c in pw) s.AppendChar(c); 
     return s; 
    } 

static void job_AcquireCredentials(object sender, AcquireCredentialsEventArgs e) 
    { 
     e.UserName = _myUserName; 
     e.Password = _pw; 
     e.Modes = AcquireCredentialModes.None; 
    }

進展：

我設法驗證（至少可以得到一個正面的審計事件）的服務器上。

我從此改變：

//don't know which one is good to use 
     job.AcquireCredentials += new EventHandler<AcquireCredentialsEventArgs>(job_AcquireCredentials); 
     _myUserName = "indes"; 
     _pw = PullPW("indes");    

     Uri url = new Uri("http://192.168.1.74:8080/live"); 
     PushBroadcastPublishFormat pubpoint = new PushBroadcastPublishFormat(); 
     pubpoint.PublishingPoint = url; 

     pubpoint.UserName = _myUserName; 
     pubpoint.Password = _pw;

要這樣：

 job.AcquireCredentials += new EventHandler<AcquireCredentialsEventArgs>(job_AcquireCredentials); 
     _myUserName = @"mediaservername\user"; 
     _pw = PullPW("user_password");    

     Uri url = new Uri("http://192.168.1.74:8080/live"); 
     PushBroadcastPublishFormat pubpoint = new PushBroadcastPublishFormat(); 
     pubpoint.PublishingPoint = url;

如果你在一邊看是否必須包括用戶名前域（域或計算機名）。這改變了服務器上失敗的審計事件，所以我可以刪除手動證書pubpoint.username和pubpoint.Password。

現在我只是處理缺乏輸出格式異常。在它上面。

我將您的代碼更改爲以下內容，看起來效果不錯。我想你的問題是你放置了LiveJob類的實例。在完成對整個流的編碼之前，您必須保持實例處於活動狀態。因此，改變使用部分，並刪除StopEncoding和處置將是確定的。

private void broadcastSourceFileToMediaServer2() 
    { 
     LiveJob job = new LiveJob(); 
     String filetoencode = @"c:\temp\niceday.wmv"; 

     LiveFileSource filesource = job.AddFileSource(filetoencode); 
     filesource.PlaybackMode = FileSourcePlaybackMode.Loop; 
     job.ActivateSource(filesource); 
     job.ApplyPreset(LivePresets.VC1Broadband4x3); 

     //don't know which one is good to use 
     job.AcquireCredentials += new EventHandler<AcquireCredentialsEventArgs>(job_AcquireCredentials); 
     _myUserName = "indes"; 
     _pw = PullPW("indes");    

     Uri url = new Uri("http://192.168.1.74:8080/live"); 
     PushBroadcastPublishFormat pubpoint = new PushBroadcastPublishFormat(); 
     pubpoint.PublishingPoint = url; 

     pubpoint.UserName = _myUserName; 
     pubpoint.Password = _pw; 

     job.PublishFormats.Add(pubpoint);  

     job.PreConnectPublishingPoint(); 

     job.StartEncoding(); 
     statusBox.Text = job.NumberOfEncodedSamples.ToString(); 
    } 

    public static string _myUserName { get; set; } 

    public static SecureString _pw { get; set; } 

    //codificação de Password a enviar 
    private static SecureString PullPW(string pw) 
    { 
     SecureString s = new SecureString(); 
     foreach (char c in pw) s.AppendChar(c); 
     return s; 
    } 

    static void job_AcquireCredentials(object sender, AcquireCredentialsEventArgs e) 
    { 
     e.UserName = _myUserName; 
     e.Password = _pw; 
     e.Modes = AcquireCredentialModes.None; 
    }

可悲的是我沒有足夠的代表評論，所以我必須寫它作爲答案。

由於您正在開始一項實時工作，爲了流式傳輸，您不應在StartEncoding之後立即調用job.StopEncoding（）。我想通常你會使用一個事件來停止編碼。如果你開始編碼並立即停止它，那麼只有邏輯上你沒有，或者只有非常小的輸出。
