## Properties
<a name="aws-properties-medialive-channel-multiplexm2tssettings-properties"></a>

`AbsentInputAudioBehavior`  <a name="cfn-medialive-channel-multiplexm2tssettings-absentinputaudiobehavior"></a>
When set to drop, output audio streams will be removed from the program if the selected input audio stream is removed from the input. This allows the output audio configuration to dynamically change based on input configuration. If this is set to encodeSilence, all output audio streams will output encoded silence when not connected to an active input stream.

`PcrControl`  <a name="cfn-medialive-channel-multiplexm2tssettings-pcrcontrol"></a>
When set to pcrEveryPesPacket, a Program Clock Reference value is inserted for every Packetized Elementary Stream (PES) header. This parameter is effective only when the PCR PID is the same as the video or audio elementary 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)

Defines the amount SCTE-35 preroll will be increased (in milliseconds) on the output. Preroll is the amount of time between the presence of a SCTE-35 indication in a transport stream and the PTS of the video frame it references. Zero means don't add pullup (it doesn't mean set the preroll to zero). Negative pullup is not supported, which means that you can't make the preroll shorter. Be aware that latency in the output will increase by the pullup amount.  
*Required*: No  
*Type*: Number
