Future<int> requestJoinSubRoom(String roomId, String userId, [ bool autoLayout = true, String? extra, ])

ZH

请求加入子房间（跨房间连麦） @param roomId 目标房间id @param userId 目标主播id @param autoLayout 是否自动布局 开启自动布局 如果被邀请方在加入邀请方房间之前发布了资源，当被邀请方加入邀请者房间成功后，服务器会把被邀请方流资源合并到邀请方视图（默认仅悬浮布局合流）上。 如果被邀请方在加入邀请方房间之前没有发布过资源，将会在被邀请方发布资源成功后，服务器会把被邀请方流资源合并到邀请方视图（默认仅悬浮布局合流）上。 双方可以主动设置合流布局。一旦主动设置过合流布局，后续RTC直播过程中设置的自动合流参数将失效。 @param extra 附加信息，默认为空 @return 0: 成功, 非0: 失败
