AWS::MediaLive::Channel AacSettings - AWS CloudFormation

AWS::MediaLive::Channel AacSettings

The settings for an AAC audio encode in the output.

The parent of this entity is AudioCodecSettings.

Syntax

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

JSON

{ "Bitrate" : Double, "CodingMode" : String, "InputType" : String, "Profile" : String, "RateControlMode" : String, "RawFormat" : String, "SampleRate" : Double, "Spec" : String, "VbrQuality" : String }

YAML

Bitrate: Double CodingMode: String InputType: String Profile: String RateControlMode: String RawFormat: String SampleRate: Double Spec: String VbrQuality: String

Properties

Bitrate

The average bitrate in bits/second. Valid values depend on the rate control mode and profile.

Required: No

Type: Double

Update requires: No interruption

CodingMode

Mono, stereo, or 5.1 channel layout. Valid values depend on the rate control mode and profile. The adReceiverMix setting receives a stereo description plus control track, and emits a mono AAC encode of the description track, with control data emitted in the PES header as per ETSI TS 101 154 Annex E.

Required: No

Type: String

Update requires: No interruption

InputType

Set to broadcasterMixedAd when the input contains pre-mixed main audio + AD (narration) as a stereo pair. The Audio Type field (audioType) will be set to 3, which signals to downstream systems that this stream contains broadcaster mixed AD. Note that the input received by the encoder must contain pre-mixed audio; MediaLive does not perform the mixing. The values in audioTypeControl and audioType (in AudioDescription) are ignored when set to broadcasterMixedAd. Leave this set to normal when the input does not contain pre-mixed audio + AD.

Required: No

Type: String

Update requires: No interruption

Profile

The AAC profile.

Required: No

Type: String

Update requires: No interruption

RateControlMode

The rate control mode.

Required: No

Type: String

Update requires: No interruption

RawFormat

Sets the LATM/LOAS AAC output for raw containers.

Required: No

Type: String

Update requires: No interruption

SampleRate

The sample rate in Hz. Valid values depend on the rate control mode and profile.

Required: No

Type: Double

Update requires: No interruption

Spec

Uses MPEG-2 AAC audio instead of MPEG-4 AAC audio for raw or MPEG-2 Transport Stream containers.

Required: No

Type: String

Update requires: No interruption

VbrQuality

The VBR quality level. This is used only if rateControlMode is VBR.

Required: No

Type: String

Update requires: No interruption
