How do I set up publishing or subscribing for a stream that has only audio or only video?

If you need to create a stream that only contains video or audio, use the publishing capabilities to define the stream as audio-only or video-only. These capabilities are invoked when creating a stream token for publishing or for subscribing.

In the publishing reports, the Audio Quality and Video Quality fields will indicate whether the stream is audio only or video only, as described in the report documentation.
