React Native
Detecting whether a stream has audio or video
In the OTSession streamCreated event includes hasAudio and hasVideo properties:
You may want to set state properties based on the hasAudio and hasVideo properties and adjust the UI for the OTSubscriber based on these state values. You may want to adjust the user interface based on whether the stream has audio or video. For example, you may want to indicate to the user whether a stream has audio or not; or you may not want to hide a subscriber if a stream does not have video.
