如何判断MediaStreamSource.SampleRequested请求的样本类型？ [英] How to tell what type of sample is requested by MediaStreamSource.SampleRequested?

问题描述

MediaStreamSource.SampleRequested处理程序获取具有s StreamDescriptor的MediaStreamSourceSampleRequestedEventArgs。

MediaStreamSource.SampleRequested handler gets MediaStreamSourceSampleRequestedEventArgs which has s StreamDescriptor.

StreamDescriptor具有属性Name，但似乎不起作用。  创建MediaStreamSource时，VideoStreamDescriptor和AudioStreamDescriptor都设置了Name属性，但在SampleRequested处理程序中Name为null。

The StreamDescriptor has property Name, but it does not seem to work.  When the MediaStreamSource is created, both VideoStreamDescriptor and AudioStreamDescriptor have their Name property set, but Name is null in the SampleRequested handler.

推荐答案

我们真的需要StreamDescriptor的名称吗？

Do we really need the name for the StreamDescriptor?

VideoStreamDescriptor和AudioStreamDescriptor有名称，因为它们可能有不同的来源。

VideoStreamDescriptor and AudioStreamDescriptor have name because they may have different sources.
