Paws::MediaConvert::AacSettings(3) User Contributed Perl Documentation Paws::MediaConvert::AacSettings(3)

Paws::MediaConvert::AacSettings

This class represents one of two things:

Arguments in a call to a service

Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.

As an example, if Att1 is expected to be a Paws::MediaConvert::AacSettings object:

  $service_obj->Method(Att1 => { AudioDescriptionBroadcasterMix => $value, ..., VbrQuality => $value  });

Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::MediaConvert::AacSettings object:

  $result = $service_obj->Method(...);
  $result->Att1->AudioDescriptionBroadcasterMix

Required when you set (Codec) under (AudioDescriptions)>(CodecSettings) to the value AAC. The service accepts one of two mutually exclusive groups of AAC settings--VBR and CBR. To select one of these modes, set the value of Bitrate control mode (rateControlMode) to "VBR" or "CBR". In VBR mode, you control the audio quality with the setting VBR quality (vbrQuality). In CBR mode, you use the setting Bitrate (bitrate). Defaults and valid values depend on the rate control mode.

Choose BROADCASTER_MIXED_AD when the input contains pre-mixed main audio + audio description (AD) as a stereo pair. The value for 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; the encoder does not perform the mixing. When you choose BROADCASTER_MIXED_AD, the encoder ignores any values you provide in AudioType and FollowInputAudioType. Choose NORMAL when the input does not contain pre-mixed audio + audio description (AD). In this case, the encoder will use any values you provide for AudioType and FollowInputAudioType.

Specify the average bitrate in bits per second. The set of valid values for this setting is: 6000, 8000, 10000, 12000, 14000, 16000, 20000, 24000, 28000, 32000, 40000, 48000, 56000, 64000, 80000, 96000, 112000, 128000, 160000, 192000, 224000, 256000, 288000, 320000, 384000, 448000, 512000, 576000, 640000, 768000, 896000, 1024000. The value you set is also constrained by the values that you choose for Profile (codecProfile), Bitrate control mode (codingMode), and Sample rate (sampleRate). Default values depend on Bitrate control mode and Profile.

AAC Profile.

Mono (Audio Description), Mono, Stereo, or 5.1 channel layout. Valid values depend on rate control mode and profile. "1.0 - Audio Description (Receiver Mix)" 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.

Rate Control Mode.

Enables LATM/LOAS AAC output. Note that if you use LATM/LOAS AAC in an output, you must choose "No container" for the output container.

Sample rate in Hz. Valid values depend on rate control mode and profile.

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

VBR Quality Level - Only used if rate_control_mode is VBR.

This class forms part of Paws, describing an object used in Paws::MediaConvert
