# AWS::MediaConnect::Flow MediaStream
<a name="aws-properties-mediaconnect-flow-mediastream"></a>

 A media stream represents one component of your content, such as video, audio, or ancillary data. After you add a media stream to your flow, you can associate it with sources and outputs that use the ST 2110 JPEG XS or CDI protocol. 

## Syntax
<a name="aws-properties-mediaconnect-flow-mediastream-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:

### JSON
<a name="aws-properties-mediaconnect-flow-mediastream-syntax.json"></a>

## Properties
<a name="aws-properties-mediaconnect-flow-mediastream-properties"></a>

`Attributes`  <a name="cfn-mediaconnect-flow-mediastream-attributes"></a>
 Attributes that are related to the media stream.  
*Required*: No  
*Type*: [MediaStreamAttributes](aws-properties-mediaconnect-flow-mediastreamattributes.md)  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`ClockRate`  <a name="cfn-mediaconnect-flow-mediastream-clockrate"></a>
 The sample rate for the stream. This value is measured in Hz.  
*Required*: No  
*Type*: Integer  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)
