Subscription and Unsubscription

For scenarios where you only publish streams without co-hosting^Note with others, subscription logic is not required.

tip

Co-hosting refers to a live streaming scenario where the host invites audience members to join as co-hosts. After switching roles, co-hosts need to subscribe to each other's streams for mutual visibility.

Subscribe to Resources

When multiple hosts are present in a live room, they need to subscribe to each other's streams to see and hear one another. Call the subscribe method in RCRTCEngine to subscribe to host resources.

• Parameters:

  Parameter	Type	Description
  userId	String	Remote host ID
  type	RCRTCMediaType	Media type
  tiny	bool	Whether to subscribe to the low-resolution stream Optional

• Sample code:

  engine.subscribe(userId, RCRTCMediaType.audio_video);

Unsubscribe from Resources

To unsubscribe, call the unsubscribe method in RCRTCEngine. This method is typically paired with subscribe, but if a user intends to leave the room, manually unsubscribing is unnecessary—the SDK handles this automatically during room exit.

• Parameters:

  Parameter	Type	Description
  userId	String	Remote host ID
  type	RCRTCMediaType	Media type

• Sample code:

  engine.unsubscribe(userId, RCRTCMediaType.audio_video);
