Question

是否可以将文件从已accidentally删除的旧媒体服务帐户传输到新媒体服务帐户。

Microsoft技术支持没有帮助。我可以将files复制到新的媒体服务帐户，但是当我测试是否可以在门户中发布资产之一时，它可以成功地进行流urls的流式传输，但是当我尝试访问这些文件时，出现网络错误

<serverError>
  <status>404</status>
  <subStatus>1000</subStatus>
  <hresult>MPE_STORAGE_RESOURCE_NOT_FOUND</hresult>
  <activityId>80028340-0004-F800-B63F-84710C7967BB</activityId>
  <serviceId>4A42CB8E-4542-0C18-2C0D-4B460D96B604</serviceId>
</serverError>

我认为它找不到清单文件。名为pc124m190o_AdaptiveStreaming_manifest.xml

元数据文件的名称也可能是潜在的问题

有人成功做到了吗？

这是我用来复制文件的代码。也许错误在这里？

这是我的媒体存储窗口的外观

Answer 1

您提到的清单文件在技术上不是流式传输所必需的。缺少的是，当您将文件复制到新的Storage帐户时，新的Media Services帐户对它们一无所知。您必须创建新资产，然后将文件复制到新资产中，以便Media Services看到它们。我建议使用存储帐户中新帐户中的Azure Media Services Explorer进行导入。

将文件从以前删除的Azure媒体服务传输到新媒体服务-有可能吗？
