Question

我在我的项目中将dotnet core与c＃和angular js UI一起使用。我正在尝试将流媒体内容上传到Azure，但是每次失败都可以。我尝试了太多方法，但没有一个起作用。请帮助我，我被卡住了。

我一直在Swank Motion Pictures的SmartTV应用程序上工作，以提供基于云的点播流电影服务。为此，我们将内容上载到Azure媒体服务资产，并使用OnDemand和SAS定位器在电视上流式传输内容。我已经将几个小方法提取到一个简单的类中，以帮助希望入门的任何人上载到Azure媒体服务。虽然此示例未提供PlayReady DRM或其他加密，但这可能是一个有用的开始。
