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

The media stream that is associated with the source, and the parameters for that association. 

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

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

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

```
{
  "[EncodingName](#cfn-mediaconnect-flow-mediastreamsourceconfiguration-encodingname)" : String,
  "[InputConfigurations](#cfn-mediaconnect-flow-mediastreamsourceconfiguration-inputconfigurations)" : [ InputConfiguration, ... ],
  "[MediaStreamName](#cfn-mediaconnect-flow-mediastreamsourceconfiguration-mediastreamname)" : String
}
```

### YAML
<a name="aws-properties-mediaconnect-flow-mediastreamsourceconfiguration-syntax.yaml"></a>

```
  [EncodingName](#cfn-mediaconnect-flow-mediastreamsourceconfiguration-encodingname): String
  [InputConfigurations](#cfn-mediaconnect-flow-mediastreamsourceconfiguration-inputconfigurations): 
    - InputConfiguration
  [MediaStreamName](#cfn-mediaconnect-flow-mediastreamsourceconfiguration-mediastreamname): String
```

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

`EncodingName`  <a name="cfn-mediaconnect-flow-mediastreamsourceconfiguration-encodingname"></a>

*Allowed values*: `jxsv | raw | smpte291 | pcm`  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`InputConfigurations`  <a name="cfn-mediaconnect-flow-mediastreamsourceconfiguration-inputconfigurations"></a>
The media streams that you want to associate with the source.   
*Required*: No
