VbrQuality: String
Properties
Bitrate-
The average bitrate in bits/second. Valid values depend on the rate control mode and profile.
Required: No
Type: Number
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: Number
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
