# FecMode

Enables column-only or column-and-row FEC for a UDP output.

- Stability: [Experimental](/cdk/api/stability.html)
- Source: [`lib/enums.ts`](https://github.com/aws/aws-cdk/blob/v2.275.0-alpha.0/packages/@aws-cdk/aws-medialive-alpha/lib/enums.ts#L746)

## Example

```ts
declare const video: medialive.EncodeConfiguration;

medialive.OutputGroupConfiguration.udp({
  name: 'udp',
  destinations: [medialive.UdpOutputDestination.rtp({ address: '203.0.113.5', port: 5000 })],
  outputs: [{
    encodes: [video],
    outputName: 'ts',
    fec: { mode: medialive.FecMode.COLUMN_AND_ROW, columnDepth: 10, rowLength: 10 },
  }],
});
```

## Properties

- `COLUMN`: [FecMode](/cdk/api/v2/docs/@aws-cdk_aws-medialive-alpha.FecMode.html) (static) — Column-only FEC.

- `COLUMN_AND_ROW`: [FecMode](/cdk/api/v2/docs/@aws-cdk_aws-medialive-alpha.FecMode.html) (static) — Column-and-row FEC (more robust).

- `value`: string — The underlying string value passed to CloudFormation.

## Methods

- `of(value: string): FecMode // chainable` (static) — A value not yet modelled by AWS CDK.
