}带子频道纯视频场景
效果
流程
和上面的 带子频道直播教学场景 流程一致，只要将频道创建参数配置里面的场景改为[alone 活动拍摄] 即可。
代码示例
和上面的 带子频道直播教学场景 代码示例一致，只要将频道创建参数配置里面的场景改为[alone 活动拍摄] 即可，具体如下：
//直播教学场景
.setScene(LiveConstant.SceneType.PPT.getDesc())
将上面配置代码修改为下面配置代码即可
//纯视频直播场景
.setScene(LiveConstant.SceneType.ALONE.getDesc())不带子频道场景
不带子频道场景只需要将上述流程和代码里面的子频道创建部分去掉即可
