Question

我遇到Azure Media Service的一些问题。我已经成功地将文件上传到Azure Media Service并将其编码为mp4，但这只适用于visual studio中的localhost。当我将以下代码部署到Azure虚拟机（Windows Datacenter 2012版）时，文件将上传，但永远不会创建编码作业。

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);

进行了一些挖掘（记录......）并找到了堆栈跟踪：
