# M2tsRateMode

The output bitrate mode of the transport stream.

- Stability: [Experimental](/cdk/api/stability.html)
- Source: [`lib/m2ts-settings.ts`](https://github.com/aws/aws-cdk/blob/v2.274.0-alpha.0/packages/@aws-cdk/aws-medialive-alpha/lib/m2ts-settings.ts#L5)

## Example

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

medialive.OutputGroupConfiguration.udp({
  name: 'udp_out',
  destinations: [medialive.UdpOutputDestination.udp({ address: '203.0.113.5', port: 5000 })],
  outputs: [{
    encodes: [video, audio],
    outputName: 'ts',
    m2tsSettings: medialive.M2tsSettings.of({
      bitrate: Bitrate.mbps(8),
      rateMode: medialive.M2tsRateMode.VBR,
      programNum: 1,
      patInterval: Duration.millis(100),
      pmtInterval: Duration.millis(100),
      scte35Control: medialive.M2tsScte35Control.PASSTHROUGH,
      dvbSdtSettings: {
        outputSdt: medialive.DvbSdtOutputMode.SDT_MANUAL,
        serviceName: 'My Service',
        repInterval: Duration.millis(2000),
      },
    }),
  }],
});
```

## Properties

- `CBR`: [M2tsRateMode](/cdk/api/v2/docs/@aws-cdk_aws-medialive-alpha.M2tsRateMode.html) (required) (static) — Constant bitrate — inserts null packets to fill the configured bitrate.

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

- `VBR`: [M2tsRateMode](/cdk/api/v2/docs/@aws-cdk_aws-medialive-alpha.M2tsRateMode.html) (required) (static) — Variable bitrate — the configured bitrate acts as the maximum.

## Methods

- `of(value: string): M2tsRateMode // chainable` (static) — A value not yet modelled by AWS CDK.
