无法将大尺寸视频上传到Windows Phone 8中的服务器

Question

我正在开发windows phone 8应用程序，我需要在其中记录并将12秒视频上传到服务器。我正在使用restsharp工具包上传视频。但是，当我尝试录制和上传视频时，从API获取Outofmemory异常或NULL响应。但是这个相同的代码在模拟器中运行良好。我对这个问题不太了解，有人可以帮忙吗？

我正在使用以下代码将视频上传到服务器。

   public void postVideofile()
    {
        customIndeterminateProgressBar.Visibility = Visibility.Visible;
        tbkloading.Visibility = Visibility.Visible;

        isoVideoFile = new IsolatedStorageFileStream(isoVideoFileName, FileMode.Open, FileAccess.Read, IsolatedStorageFile.GetUserStoreForApplication());


        StreamReader reader = new StreamReader(isoVideoFile);


        DateTime dt = DateTime.Now;
        ////preparing RestRequest by adding server url, parameteres and files...
        RestRequest request = new RestRequest("http://slv1.socialnetgate.com/v1/files/postVideofile", Method.POST);

        request.AddParameter("apikey", "RVY0VnVLUDhQSHZST2hFM04xcnFnZDkzU2J2bGtZVVM1S2NNaXY2NHh4cmhhdEM5cjMyMTJaMXA");
        request.AddParameter("userID", "64");

        request.AddFile("uploadedfile", App.ReadToEnd(reader.BaseStream), isoVideoFileName);

        request.AddParameter("uploadID", dt);



        //calling server with restClient
        RestClient restClient = new RestClient();
        restClient.ClearHandlers();
        restClient.AddHandler("application/json", new XmlDeserializer());
        restClient.AddHandler("text/json", new XmlDeserializer());

        restClient.ExecuteAsync(request, (response) =>
        {
            if (response.StatusCode == HttpStatusCode.OK)
            {
                string err = response.ErrorMessage;
                String res = response.Content;


                JObject results = JObject.Parse(res);
                string jsonStatus = (string)results["header"]["description"];

                string url = (string)results["URL"];







            }
            else
            {
                MessageBox.Show("Check your internet connection! Please try again");

            }
        });
    }
