TypeScript (source)	`@aws-cdk/aws-medialive-alpha` » `Lut`

The S3 location of a 3D LUT (look-up table) file used by a color-correction rule.

MediaLive reads the LUT from S3 at runtime, so the file must be in an S3 bucket — the URI must use the s3:// or s3ssl:// protocol. Unlike a FileLocation, a LUT has no credentials.

Use the static factory methods to create one from an S3 bucket (which uses the secure s3ssl:// form and auto-grants the channel role read access) or a raw S3 URL.

Example

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

new medialive.Channel(stack, 'Channel', {
  inputs: [{ input }],
  colorCorrections: [{
    inputColorSpace: medialive.ColorSpace.REC_601,
    outputColorSpace: medialive.ColorSpace.REC_709,
    lut: medialive.Lut.fromBucket(bucket, 'luts/rec601-to-rec709.cube'),
  }],
  outputGroups: [
    medialive.OutputGroupConfiguration.hls({
      name: 'hls',
      destinations: [destination],
      outputs: [{ encodes: [video], outputName: 'video' }],
    }),
  ],
});

Initializer

static fromBucket(bucket, key)🔹

public static fromBucket(bucket: IBucket, key: string): Lut

Parameters

bucket IBucket — The S3 bucket containing the LUT file.
key string — The object key within the bucket (e.g. 'luts/rec709.cube').

Returns

Lut

Reference a LUT file in an S3 bucket.

Uses the secure s3ssl:// form and automatically grants the channel role read access.

static url(url)🔹

public static url(url: string): Lut

Parameters

url string — The s3:// or s3ssl:// URL of the LUT file.

Returns
