Experimental

@aws-cdk/aws-medialive-alpha is an experimental (alpha) package: its API may change in any release, without a major version bump.

Policy for how MediaLive identifies the audio stream when selecting by language, on a transport-stream PMT update.

Stability

Experimental

Source

lib/audio-selector.ts

Example

declare const stack: Stack;
declare const input: medialive.IInput;
declare const bucket: s3.IBucket;
declare const video: medialive.EncodeConfiguration;

new medialive.Channel(stack, 'Channel', {
  inputs: [{
    input,
    audioSelectors: [
      medialive.AudioSelector.byLanguage('eng', 'eng', medialive.AudioLanguageSelectionPolicy.STRICT),
    ],
    captionSelectors: [
      medialive.CaptionSelector.embedded('embedded'),
    ],
    videoSelector: {
      colorSpace: medialive.VideoColorSpace.HDR10,
      colorSpaceUsage: medialive.VideoColorSpaceUsage.FORCE,
      selectBy: medialive.VideoSelection.byProgramId(1),
    },
  }],
  outputGroups: [
    medialive.OutputGroupConfiguration.hls({
      name: 'hls',
      destinations: [medialive.OutputDestination.toBucket(bucket, 'live/stream')],
      outputs: [{ encodes: [video], outputName: 'hls_out' }],
    }),
  ],
});

On a PMT update, fall back to another audio stream of the same type in the program if a stream with the same language can't be found.

Strictly identify audio by its language descriptor.

If the matching language is no longer present after a PMT update, mute is encoded until the language returns.
