【问题标题】:Creation of an Azure Media Service Job fails after deploying to server (iis8)部署到服务器 (iis8) 后,创建 Azure 媒体服务作业失败
【发布时间】:2014-01-06 00:53:37
【问题描述】:

我在使用 Azure 媒体服务时遇到了一些问题。我已成功将文件上传到 Azure 媒体服务并将其编码为 mp4,但这仅适用于 Visual Studio 中的 localhost。当我将以下代码部署到 Azure 虚拟机 Windows Datacenter 2012 版时,文件已上传但从未创建编码作业

非常感谢任何帮助!

这是我用来创建作业的代码:

                // Declare a new job.
                job= _context.Jobs.Create("New Job");

                // Get a media processor reference, and pass to it the name of the 
                // processor to use for the specific task.
                IMediaProcessor processor = GetLatestMediaProcessorByName("Windows Azure Media Encoder");

            // Create a task with the encoding details, using a string preset.
            ITask task = job.Tasks.AddNew("LSVEncodingTask_" + v.CompanyId + "_user" + v.UserId,
                processor,
                "H264 Broadband 1080p",
                TaskOptions.ProtectedConfiguration);

            // Specify the input asset to be encoded.
            task.InputAssets.Add(asset);

            // Add an output asset to contain the results of the job. 
            // This output is specified as AssetCreationOptions.None, which 
            // means the output asset is not encrypted. 
            task.OutputAssets.AddNew("output asset",
                AssetCreationOptions.None);

            // Use the following event handler to check job progress.  
            job.StateChanged += new
                EventHandler<JobStateChangedEventArgs>(StateChanged);

            // Launch the job.
            job.Submit();

            // Check job execution and wait for job to finish. 
            Task progressJobTask = job.GetExecutionProgressTask(CancellationToken.None);

编辑:

进行了一些挖掘(记录...)并找到了堆栈跟踪:

System.Security.Cryptography.CryptographicException: Access is denied.

【问题讨论】:

  • 告诉我们到目前为止您为诊断/调试问题所做的尝试?有像 Fiddler 这样的工具非常适合跟踪 Web 请求。有诸如 Windows 事件日志之类的东西,您可以在其中查找可疑条目等。请先尝试自己解决问题,然后在此处提供尝试的解决方案和失败代码/堆栈跟踪以提供帮助。

【解决方案1】:

找到解决办法here:

在 IIS7 上运行时 - 您可以指定加载应用程序池的用户配置文件。这使您可以访问应用程序的每个用户商店 池帐户。
