Question

I am having some problems with the Azure Media Service. I have successfully managed to upload a file to Azure Media Service and encoded it as mp4, but this will only work on localhost in visual studio. When I deploy the following code to a Azure Virtual Machine, Windows Datacenter 2012 edition, the file is uploaded but the encoding job is never created.

Any help is much appreciated!

This is the code I use to create the job:

                // 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);

EDIT:

Did some digging (logging...) and found the stack trace:
