Azure Media Services Error 400

Question

현재 앱을 만들고 있는데에 webjob을 작성하려고합니다. blob 저장소에 업로드 한 mp4 파일을 가져 와서 인코딩하고 하늘색 미디어 서비스를 사용하여 스트리밍 할 준비가 된 자산을 만듭니다.

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(); 
 
     }

나는 내가에 업로드 단일 스토리지 계정을 사용하고 있습니다. 내가 상관없이 내가이 로그 오류들에게 새로운 CloudMediaContext (새 MediaServicesCredentials을

Answer 1

컨텍스트 = 원인이 라인

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

( 에 의한하려고 무엇을이 오류 (400)를 받고 없습니다 계속 accName, accKey)); 은 외부에없는 ConvertAndPrepareVideo 메서드 내에서 설정해야합니다.
