来自 Blob 存储的 Azure 媒体服务

Question

我找到了一些相关的答案，但 none 解释了我是否真的需要来自 https://azure.microsoft.com/en-us/documentation/articles/media-services-copying-existing-blob/ 的 Azure 媒体服务团队示例的所有代码我只想将文件从 blob 上传到 Azure 媒体服务。像这样：

  var uploadFilePath = blobUrl;
  var uploadAsset = _context.Assets.Create(Path.GetFileNameWithoutExtension(uploadFilePath), AssetCreationOptions.None);
  var assetFile = uploadAsset.AssetFiles.Create(Path.GetFileName(uploadFilePath));
  assetFile.Upload(uploadFilePath);

但我得到

AggregateException was unhandled by user code, "An exception of type 'System.AggregateException' occurred in mscorlib.dll but was not handled in user code"

堆栈跟踪

附加信息：出现一个或多个错误。

Answer 1

资产文件上传方法不支持从 blob 上传。它仅适用于本地文件。关于异常，您应该在内部异常消息属性中看到消息。您可以使用 azure 媒体服务扩展（或查看它是如何完成的）https://github.com/Azure/azure-sdk-for-media-services-extensions 从现有 blob 创建资产。
