Overview

Note:

When passing AacSettings as input to an Aws::Client method, you can use a vanilla Hash:

{
  audio_description_broadcaster_mix: "BROADCASTER_MIXED_AD", # accepts BROADCASTER_MIXED_AD, NORMAL
  bitrate: 1,
  codec_profile: "LC", # accepts LC, HEV1, HEV2
  coding_mode: "AD_RECEIVER_MIX", # accepts AD_RECEIVER_MIX, CODING_MODE_1_0, CODING_MODE_1_1, CODING_MODE_2_0, CODING_MODE_5_1
  rate_control_mode: "CBR", # accepts CBR, VBR
  raw_format: "LATM_LOAS", # accepts LATM_LOAS, NONE
  sample_rate: 1,
  specification: "MPEG2", # accepts MPEG2, MPEG4
  vbr_quality: "LOW", # accepts LOW, MEDIUM_LOW, MEDIUM_HIGH, HIGH
}

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.

Instance Attribute Details

#audio_description_broadcaster_mixString

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.

Possible values:

  • BROADCASTER_MIXED_AD
  • NORMAL

Returns:

  • (String)

    Choose BROADCASTER_MIXED_AD when the input contains pre-mixed main audio + audio description (AD) as a stereo pair.

#bitrateInteger

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.

Returns:

  • (Integer)

    Specify the average bitrate in bits per second.

#codec_profileString

AAC Profile.

Possible values:

  • LC
  • HEV1
  • HEV2

Returns:

  • (String)

    AAC Profile.

#coding_modeString

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.

Possible values:

  • AD_RECEIVER_MIX
  • CODING_MODE_1_0
  • CODING_MODE_1_1
  • CODING_MODE_2_0
  • CODING_MODE_5_1

Returns:

  • (String)

    Mono (Audio Description), Mono, Stereo, or 5.1 channel layout.

#rate_control_modeString

Rate Control Mode.

Possible values:

  • CBR
  • VBR

Returns:

  • (String)

    Rate Control Mode.

#raw_formatString

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.

Possible values:

  • LATM_LOAS
  • NONE

Returns:

  • (String)

    Enables LATM/LOAS AAC output.

#sample_rateInteger

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

Returns:

  • (Integer)

    Sample rate in Hz.

#specificationString

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

Possible values:

  • MPEG2
  • MPEG4

Returns:

  • (String)

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

#vbr_qualityString

VBR Quality Level - Only used if rate_control_mode is VBR.

Possible values:

  • LOW
  • MEDIUM_LOW
  • MEDIUM_HIGH
  • HIGH

Returns:

  • (String)

    VBR Quality Level - Only used if rate_control_mode is VBR.
