Subscribing Remote Streams: iOS SDK – Video API

The EnxRoom.subscribe() method is used to receive the media stream of other users connected to the Room. You must call this method for each participant’s media stream individually to receive it. 

You don’t need to subscribe to your Local Stream as EnableX facilitates the publisher to receive their own Screen Sharing and Canvas Streaming without explicitly subscribing to it. In short, a user must only subscribe to the Remote Streams in the Room. 

Refer to Handle Active Talkers section below for more details.

Method: -(void)subscribe:(EnxStream *)stream;

Parameters: stream – The Stream object that needs to be subscribed.
