Question

我使用以下代码将DRM应用于我的视频文件。但是任务正在失败，我该怎么办才能让它发挥作用？

我可以看到“我的PlayReady任务”达到100％并突然抛出错误。

错误细节：我的PlayReady任务 MediaProcessor：执行任务期间发生异常

几天前，它正在发挥作用。不确定现在发生了什么？

您使用的是什么播放许可服务器？从代码的角度来看，一切看起来都很好。由于播放器保护预设未包含在样本中，我假设它看起来类似于以下文章中的示例：http://msdn.microsoft.com/en-us/library/windowsazure/dn189154.aspx 请确保可以从公共网络访问licenseAquisitionURL中的值，并且您的keySeedValue或keyID和contentKey仍然有效。

是否存在可以从失败的实例共享的jobID？
