# 使用 Amazon Chime SDK 媒体管道事件
<a name="media-pipe-events"></a>

每种类型的媒体管道会发送生命周期事件，用于触发通知和启动下游工作流程。使用会议管道事件的部分示例包括：
+ 媒体管道完成后处理捕获的媒体。
+ 如果媒体管道出现暂时故障，则通知会议参与者。
+ 如果媒体管道出现永久故障，则停止会议。

您可以向亚马逊 EventBridge、亚马逊简单通知服务 (SNS) 和亚马逊简单队列服务 (SQS) 发送事件。有关更多信息，请参阅 *Amazon EventBridge 用户指南*中的[来自 AWS 服务的事件](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-service-event.html)。
