什么原因导致使用附加Blob时发生编码错误？

问题描述

所以我的情况是，在创建输出资产时，具有BlobType：BlockBlob的Blob成功编码，但是具有AppendBlob的BlobType没有编码... 我要附加4mb的块。

1. 创建InputAsset

    var asset = await _client.Assets.CreateOrUpdateAsync(_apiAccess.ResourceGroup,_apiAccess.AccountName,request.InputAssetName,new Microsoft.Azure.Management.Media.Models.Asset(container: request.InputAssetContainer));
    
    var response = await _client.Assets.ListContainerSasAsync(_apiAccess.ResourceGroup,permissions: AssetContainerPermission.ReadWrite,expiryTime: DateTime.UtcNow.AddHours(4).ToUniversalTime());
    
                request.InputAssetStorageUri = new Uri(response.AssetContainerSasUrls.First());
    
                await AppendBlobAsync(request);
    
                return asset;

2）AppendBlobAsync方法，实际上会附加4mb的块

 BlobServiceClient blobServiceClient = new BlobServiceClient("conn");
            BlobContainerClient containerClient = blobServiceClient.GetBlobContainerClient(request.InputAssetContainer);
            await containerClient.CreateIfNotExistsAsync();
            //There we would have stream
            var appendBlobClient = containerClient.GetAppendBlobClient(request.BlobName);
            await appendBlobClient.CreateIfNotExistsAsync();
            //await using var memoryStream = new MemoryStream();
            //await request.File.CopyToAsync(memoryStream);
            //memoryStream.Position = 0;

            var file =  File.OpenRead("C:\\Projects\\TestChunk.mp4");
            Stream stream = new MemoryStream();
            file.CopyTo(stream);
            stream.Position = 0;
            await appendBlobClient.AppendBlockAsync(stream);

3）创建输出资产

public async Task<Asset> CreateOutputAssetAsync(MediaServiceRequest request)
        => await _client.Assets.CreateOrUpdateAsync(_apiAccess.ResourceGroup,request.OutputAssetName,new Microsoft.Azure.Management.Media.Models.Asset())

4）编码

  public async Task<Job> EncodeAsync(MediaServiceRequest request)
        {
            JobInput jobInput = new JobInputAsset(assetName: request.InputAssetName);

            JobOutput[] jobOutputs =
            {
                new JobOutputAsset(request.OutputAssetName),};

            return await _client.Jobs.CreateAsync(
                _apiAccess.ResourceGroup,request.TransformerName,request.JobName,new Job
                {
                    Input = jobInput,Outputs = jobOutputs,});
        }

请帮助...
