Properties for an audio-silence failover condition.

Example

declare const stack: Stack;
declare const primaryInput: medialive.IInput;
declare const secondaryInput: medialive.IInput;
declare const audioSelector: medialive.AudioSelector;
declare const video: medialive.EncodeConfiguration;
declare const audio: medialive.EncodeConfiguration;
declare const bucket: s3.IBucket;

new medialive.Channel(stack, 'Channel', {
  inputs: [{
    input: primaryInput,
    automaticInputFailover: {
      secondaryInput,
      inputPreference: medialive.InputPreference.PRIMARY_INPUT_PREFERRED,
      errorClearTime: Duration.seconds(3),
      failoverConditions: [
        medialive.FailoverCondition.inputLoss({ threshold: Duration.millis(1500) }),
        medialive.FailoverCondition.audioSilence({ audioSelector, threshold: Duration.seconds(2) }),
        medialive.FailoverCondition.videoBlack({ blackDetectThreshold: 0.1, threshold: Duration.seconds(1) }),
      ],
    },
  }, {
    // The secondary input must also be attached to the channel as its own input.
    input: secondaryInput,
  }],
  outputGroups: [
    medialive.OutputGroupConfiguration.hls({
      name: 'hls',
      destinations: [medialive.OutputDestination.toBucket(bucket, 'live/stream')],
      outputs: [{ encodes: [video, audio], outputName: 'hls_out' }],
    }),
  ],
});

Properties

Name	Type	Description
audioSelector🔹	AudioSelector	The audio selector (defined on the input attachment) that MediaLive monitors for silence.
threshold?🔹	Duration	How long the audio must be silent (audio loss, or quieter than -50 dBFS) before failover occurs.

audioSelector🔹

Type: AudioSelector

The audio selector (defined on the input attachment) that MediaLive monitors for silence.

Pass the same AudioSelector instance you put in the attachment's audioSelectors — select your most important rendition.

threshold?🔹

Type: Duration (optional, default: MediaLive service default)

How long the audio must be silent (audio loss, or quieter than -50 dBFS) before failover occurs.
