Error in Job created to convert assest content to MP4 format in Windows Azure Media Service

Question

Hi,
I am have created application which create media service channel and use Wirecast for live streaming on the channel. once event is completed video should be available for downloading.
I have created job to convert asset content to MP4 format, job is created but with error:
AssetFile's name doesn't match the blob file name, the AssetFile's name is not well formed or the blob file is not present in the Asset's container.
Below is the code for job creation:
 var outputAsset = _context.Assets.Where(p => p.Name == "Demo18032015_DefaultProgram").FirstOrDefault();
            IAsset encodedAsset =
                EncodeToAdaptiveBitrateMP4s(outputAsset, AssetCreationOptions.None);
static public IAsset EncodeToAdaptiveBitrateMP4s(IAsset asset, AssetCreationOptions options)
            // Prepare a job with a single task to transcode the specified asset
            // into a multi-bitrate asset.
            IJob job = _context.Jobs.CreateWithSingleTask(
                MediaProcessorNames.AzureMediaEncoder,
                MediaEncoderTaskPresetStrings.H264AdaptiveBitrateMP4Set720pForiOSCellularOnly,
                asset,
                "fdemo18032015defaultprogram",
                options);
            Console.WriteLine("Submitting transcoding job...");
            // Submit the job and wait until it is completed.
            job.Submit();
            job = job.StartExecutionProgressTask(
                j =>
                    Console.WriteLine("Job state: {0}", j.State);
                    Console.WriteLine("Job progress: {0:0.##}%", j.GetOverallProgress());
                CancellationToken.None).Result;
            Console.WriteLine("Transcoding job finished.");
            IAsset outputAsset = job.OutputMediaAssets[0];
            return outputAsset;
 Here I am first searching asset in content where video is stored and then creating job.
I am using windowsazure.mediaservices version="3.1.0.1" and windowsazure.mediaservices.extensions version="2.0.0.3" dll.
Please help me with the issue.

The error is as expected - the on-demand encoders in our service (Azure Media Encoder, etc.) do not yet support handling of input Assets that are archives from a live stream.
However, we are close to shipping an update to our service that will provide such support. Please watch out for our blog posts in http://azure.microsoft.com/blog/topics/media-services/
