Example

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

const video = medialive.EncodeConfiguration.video({
  name: 'video_720p',
  codec: medialive.VideoCodecSettings.h264({
    rateControl: medialive.H264RateControl.cbr({ bitrate: Bitrate.mbps(3) }),
    framerate: medialive.Framerate.FPS_30,
  }),
  width: 1280,
  height: 720,
});

const audio = medialive.EncodeConfiguration.audio({
  name: 'audio_aac',
  codec: medialive.AudioCodecSettings.aac({ bitrate: Bitrate.kbps(192) }),
});

new medialive.Channel(stack, 'Channel', {
  inputs: [{ input }],
  outputGroups: [
    medialive.OutputGroupConfiguration.hls({
      name: 'hls',
      destinations: [medialive.OutputDestination.toBucket(bucket, 'live/stream')],
      outputs: [{ encodes: [video, audio], outputName: 'hls_out' }],
    }),
  ],
});
