Publishing Local Stream: iOS SDK – Video API

After initializing the stream, you need to publish it in the room so that the other users in the room can see and hear the user.  The methods to publish, unpublish, and close a local stream are explained in this section.

Publish Local Stream

The EnxRoom.publish() method publishes a local stream in the connected room. 

Class: EnxRoom

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

Parameters:

• stream– Initiated Stream Object

Delegate Methods:

• - room:didPublishStream: – Acknowledgment to the Stream publisher when the stream gets published.
• - room:didAddedStream: – Notification to everyone in the Room when a new stream is published in the Room.

[room publish:localStream];

- (void)room:(EnxRoom *)room didPublishStream:(EnxStream *)stream{
	// Your stream is published

Delegate Method: – room:didRemovedStream: – Notification to everyone in the Room when a Stream is removed from the Room.

[room unpublish]; // To unpublish all Local Streams

-(void)room:(EnxRoom *)room didRemovedStream:(EnxStream *)stream{
     // To announce in the room that a stream has been removed from the Room.
}

Error Codes / Exceptions

5029	Repeated unpublish call made while the previous request is in process.
5030	Non-Contextual use of method when the user tries to unpublish a stream before publishing it.
