跳躍點藍色不起作用 - 視頻

Question

我是MVC中的新成員，我試圖播放存儲在VARBINARY（max）字段中的數據庫（SQL）中的視頻。我已經可以在我的WEB應用程序中顯示視頻，但問題在於progres欄。當我執行跳轉到另一個點時，它會出現但不起作用。我閱讀了一些關於這方面的材料，但我無法解決它。我認爲問題是關於緩衝（開始/結束）。以下是我的代碼。

控制器：

public ActionResult Media(int id) 
{ 
    byte[] teste = null; 
    string query1 = "SELECT * FROM Movie WHERE ID = '"+id+"'"; 
    using (SqlConnection connection1 = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString)) 
    using (SqlCommand command1 = new SqlCommand(query1, connection1)) 
    { 
     connection1.Open(); 
     var reader = command1.ExecuteReader(); 

     if (reader.HasRows) 
     { 
      reader.Read(); 
      teste = (byte[])reader["Movie"]; 
     } 
     connection1.Close(); 
    } 
    var memoryStream = new MemoryStream(teste); 
    return new FileStreamResult(memoryStream, Convert.ToString(teste)); 

} 

查看：

<video width="400" controls> 
     <source src="@Url.Action("Media","Account",new { id = 3 })" type="video/mp4"> 
    </video> 

下跳點出現，但不工作：

      if (range.Length > 2 && range[2] != "") endbyte = Convert.ToInt64(range[2]); 
      //If the start byte is not equal to zero, that means the user is requesting partial content. 
      if (startbyte != 0 || endbyte != fSize - 1 || range.Length > 2 && range[2] == "") 
      { statusCode = 206; }//Set the status code of the response to 206 (Partial Content) and add a content range header.

     Response.StatusCode = statusCode;

     Response.AddHeader("Content-Length", desSize.ToString()); 
     Response.AddHeader("Content-Range", string.Format("bytes {0}-{1}/{2}", startbyte, endbyte, fSize)); 


     var fs = new MemoryStream(teste,(int)startbyte, (int)desSize); 
     return new FileStreamResult(fs, userFile.FileType); 
    }
