# CmafIngestOutputDefinition

Output definition for a CMAF Ingest output group.

CMAF Ingest requires one media track (video or audio) per output. In-band captions (burn-in,
embedded) can ride alongside the primary encode.

- Stability: [Experimental](/cdk/api/stability.html)
- Source: [`lib/outputs.ts`](https://github.com/aws/aws-cdk/blob/v2.275.0-alpha.0/packages/@aws-cdk/aws-medialive-alpha/lib/outputs.ts#L472)

## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as medialive_alpha from '@aws-cdk/aws-medialive-alpha';

declare const encodeConfiguration: medialive_alpha.EncodeConfiguration;
const cmafIngestOutputDefinition: medialive_alpha.CmafIngestOutputDefinition = {
  encode: encodeConfiguration,
  outputName: 'outputName',

  // the properties below are optional
  captions: [encodeConfiguration],
  nameModifier: 'nameModifier',
};
```

## Properties

- `captions`: [EncodeConfiguration](/cdk/api/v2/docs/@aws-cdk_aws-medialive-alpha.EncodeConfiguration.html)[] — Caption encodes that ride alongside the primary encode.

  **Default:** no captions on this output

  Only in-band caption types are
  allowed (burn-in, embedded) — out-of-band captions must go in their own output.

- `encode`: [EncodeConfiguration](/cdk/api/v2/docs/@aws-cdk_aws-medialive-alpha.EncodeConfiguration.html) (required) — The primary encode for this output — one video or one audio track.

- `nameModifier`: string — A string concatenated to the end of the destination file name.

  **Default:** no name modifier

- `outputName`: string (required) — The name of this output.

  Must be unique across all outputs in the channel.
