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

The configuration settings that apply to the entire channel.

The parent of this entity is EncoderSettings.

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

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

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

```
{
  "[InitialAudioGain](#cfn-medialive-channel-globalconfiguration-initialaudiogain)" : {{Integer}},

}
```

### YAML

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

`InitialAudioGain`  <a name="cfn-medialive-channel-globalconfiguration-initialaudiogain"></a>
The value to set the initial audio gain for the channel.  
*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)

`InputEndAction`  <a name="cfn-medialive-channel-globalconfiguration-inputendaction"></a>
Indicates the action to take when the current input completes (for example, end-of-file). When switchAndLoopInputs is configured, MediaLive restarts at the beginning of the first input. When "none" is configured, MediaLive transcodes either black, a solid color, or a user-specified slate images per the "Input Loss Behavior" configuration until the next input switch occurs (which is controlled through the Channel Schedule API).  
*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)

`InputLossBehavior`  <a name="cfn-medialive-channel-globalconfiguration-inputlossbehavior"></a>
The settings for system actions when the input is lost.  
*Required*: No  
*Type*: [InputLossBehavior](aws-properties-medialive-channel-inputlossbehavior.md)  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`OutputLockingMode`  <a name="cfn-medialive-channel-globalconfiguration-outputlockingmode"></a>
Indicates how MediaLive pipelines are synchronized. PIPELINELOCKING - MediaLive attempts to synchronize the output of each pipeline to the other. EPOCHLOCKING - MediaLive attempts to synchronize the output of each pipeline to the Unix epoch.  
*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)

`OutputLockingSettings`  <a name="cfn-medialive-channel-globalconfiguration-outputlockingsettings"></a>
Property description not available.  
*Required*: No  
*Type*: [OutputLockingSettings](aws-properties-medialive-channel-outputlockingsettings.md)  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`OutputTimingSource`  <a name="cfn-medialive-channel-globalconfiguration-outputtimingsource"></a>
Indicates whether the rate of frames emitted by the Live encoder should be paced by its system clock (which optionally might be locked to another source through NTP) or should be locked to the clock of the source that is providing the input stream.  
*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)

`SupportLowFramerateInputs`  <a name="cfn-medialive-channel-globalconfiguration-supportlowframerateinputs"></a>
Adjusts the video input buffer for streams with very low video frame rates. This is commonly set to enabled for music channels with less than one video frame per second.  
*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)
