# AWS::MediaLive::Channel SrtOutputSettings
<a name="aws-properties-medialive-channel-srtoutputsettings"></a>

Srt Output Settings

## Syntax
<a name="aws-properties-medialive-channel-srtoutputsettings-syntax"></a>

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

### JSON
<a name="aws-properties-medialive-channel-srtoutputsettings-syntax.json"></a>

```
{
  "[BufferMsec](#cfn-medialive-channel-srtoutputsettings-buffermsec)" : {{Integer}},
  "[ContainerSettings](#cfn-medialive-channel-srtoutputsettings-containersettings)" : {{UdpContainerSettings}},
  "[Destination](#cfn-medialive-channel-srtoutputsettings-destination)" : {{OutputLocationRef}},
  "[EncryptionType](#cfn-medialive-channel-srtoutputsettings-encryptiontype)" : {{String}},
  "[Latency](#cfn-medialive-channel-srtoutputsettings-latency)" : {{Integer}}
}
```

### YAML
<a name="aws-properties-medialive-channel-srtoutputsettings-syntax.yaml"></a>

```
  [BufferMsec](#cfn-medialive-channel-srtoutputsettings-buffermsec): {{Integer}}
  [ContainerSettings](#cfn-medialive-channel-srtoutputsettings-containersettings): {{
    UdpContainerSettings}}
  [Destination](#cfn-medialive-channel-srtoutputsettings-destination): {{
    OutputLocationRef}}
  [EncryptionType](#cfn-medialive-channel-srtoutputsettings-encryptiontype): {{String}}
  [Latency](#cfn-medialive-channel-srtoutputsettings-latency): {{Integer}}
```

## Properties
<a name="aws-properties-medialive-channel-srtoutputsettings-properties"></a>

`BufferMsec`  <a name="cfn-medialive-channel-srtoutputsettings-buffermsec"></a>
SRT output buffering in milliseconds. A higher value increases latency through the encoder. But the benefits are that it helps to maintain a constant, low-jitter SRT output, and it accommodates clock recovery, input switching, input disruptions, picture reordering, and so on. Range: 0-10000 milliseconds.  
*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)

`ContainerSettings`  <a name="cfn-medialive-channel-srtoutputsettings-containersettings"></a>
The container settings for the SRT output.  
*Required*: No  
*Type*: [UdpContainerSettings](aws-properties-medialive-channel-udpcontainersettings.md)  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`Destination`  <a name="cfn-medialive-channel-srtoutputsettings-destination"></a>
Reference to an OutputDestination ID defined in the channel.  
*Required*: No  
*Type*: [OutputLocationRef](aws-properties-medialive-channel-outputlocationref.md)  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`EncryptionType`  <a name="cfn-medialive-channel-srtoutputsettings-encryptiontype"></a>
The encryption level for the content. Valid values are AES128, AES192, AES256. You and the downstream system should plan how to set this field because the values must not conflict with each other.  
*Required*: No  
*Type*: String  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`Latency`  <a name="cfn-medialive-channel-srtoutputsettings-latency"></a>
The latency value, in milliseconds, that is proposed during the SRT connection handshake. SRT will choose the maximum of the values proposed by the sender and receiver. Range: 40-16000 milliseconds.  
*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)
