Azure Media Services Error 400

Question

私は現在、アプリケーションを構築中で、にwebjobを書き込もうとしています。私はBLOBストレージにアップロードして、私がエンコードして、晴れのメディアサービスを使用してストリーミングできる準備をしています。

public class Functions 
 
    { 
 
     // This function will get triggered/executed when a new message is written 
 
     // on an Azure Queue called queue. 
 
     static string accName = "copied from portal "; 
 
     static string accKey = "as above"; 
 
     static CloudMediaContext context = new CloudMediaContext(accName,accName); 
 
     // Use the cached credentials to create CloudMediaContext. 
 
     //static CloudMediaContext context = new CloudMediaContext(accName,accKey); 
 
     public static void ProcessVideo(
 
     [QueueTrigger("videorequest")] VideoBlobInformation blobInfo, 
 
     [Blob("{ProfileId}/{BlobName}", FileAccess.Read)] Stream input, 
 
     [Blob("{ProfileId}/{BlobNameWithoutExtension}_stream.mp4")] CloudBlockBlob outputBlob) 
 
     { 
 
      VideoBlobInformation b = blobInfo; 
 
      using (Stream output = outputBlob.OpenWrite()) 
 
      { 
 
       ConvertAndPrepareVideo(b,input, output); 
 
      } 
 
      // Entity Framework context class is not thread-safe, so it must 
 
      // be instantiated and disposed within the function. 
 
      using (impulsevidContext db = new impulsevidContext()) 
 
      { 
 
       //var id = blobInfo.ProfileId; 
 
       //Video ad = db.Videos.Find(id); 
 
       //if (ad == null) 
 
       //{ 
 
        // throw new Exception(String.Format("AdId {0} not found, can't create thumbnail", id.ToString())); 
 
       //} 
 
       //ad.StreamUrl = outputBlob.Uri.ToString(); 
 
       //db.SaveChanges(); 
 
      } 
 
      
 
     } 
 
     public static void ConvertAndPrepareVideo(VideoBlobInformation info,Stream input, Stream output) 
 
     { 
 
      var storageAccount = new CloudStorageAccount(new StorageCredentials("accnameofstorage", "storage account associated with azure media services"), true); 
 
      //output all webjob input blobs into a container -mediacontroller- 
 
      var cloudBlobClient = storageAccount.CreateCloudBlobClient(); 
 
      var mediaBlobContainer = cloudBlobClient.GetContainerReference("impfile"); 
 
      mediaBlobContainer.CreateIfNotExists(); 
 
      IAsset sourceAsset = context.Assets.Where(a => a.Id == info.VideoId).First(); 
 
     }

私は私がにアップロード単一のストレージアカウントを使用しています。 私は関係なく、私はこのラインで

Answer 1

コンテキスト=新しいCloudMediaContext（新MediaServicesCredentialsに（ をこのログエラーが発生し

IAsset sourceAsset = context.Assets.Where(a => a.Id == info.VideoId).First();

を起こしてみてください何このエラー400を取得していない保ちますaccName、 accKey））; をConvertAndPrepareVideoメソッド内に設定しないでください。
