Issue while copying existing blob to Azure Media Services

Question

We are trying to copy the existing blob to AMS but it is not getting copied. Blob resides in storage account 1 and AMS is associated with storage account 2. All the accounts including AMS are in the same location.

   await destinationBlob.StartCopyAsync(new Uri(sourceBlob.Uri.AbsoluteUri + signature));

When visualizing the AMS Storage Account using Blob Storage explorer, asset folders are getting created but with no blobs in it. Also, within the Media explorer, we can see the assets listed in the AMS but when clicked, not found exception is thrown. Basically they are not getting fully copied into the AMS.

However, when we use same code and attach a new AMS to the blob storage account (storage account1) where the actual blob resides, copy is working fine.

I have not reproduce your issue. But there is a code sample to copy existing blob to Azure media services via .NET SDK. Please try to copy the Blob using StartCopyFromBlob or StartCopyFromBlobAsync(the Azure storage client library 4.3.0). Below is the code snippet in the code sample :

                destinationBlob.StartCopyFromBlob(new Uri(sourceBlob.Uri.AbsoluteUri + signature));

                while (true)
                {
                    // The StartCopyFromBlob is an async operation, 
                    // so we want to check if the copy operation is completed before proceeding. 
                    // To do that, we call FetchAttributes on the blob and check the CopyStatus. 
                    destinationBlob.FetchAttributes();
                    if (destinationBlob.CopyState.Status != CopyStatus.Pending)
                    {
                        break;
                    }
                    //It's still not completed. So wait for some time.
                    System.Threading.Thread.Sleep(1000);
                }
