Flow

The Flow resource allows you to create and manage AWS MediaConnect Flows for transporting live video over the internet. This resource provides an efficient way to configure the flow of media from sources to destinations.

Minimal Example

Create a basic MediaConnect Flow with required properties and some common optional configurations.

import AWS from "alchemy/aws/control";

const mediaConnectFlow = await AWS.MediaConnect.Flow("myMediaFlow", {
  name: "MyLiveStreamFlow",
  source: {
    name: "MySource",
    url: "rtmp://my-source-url",
    protocol: "rtmp"
  },
  sourceMonitoringConfig: {
    clockRate: 90000,
    audioLevel: 0.5
  },
  availabilityZone: "us-west-2a"
});

Advanced Configuration

Configure a MediaConnect Flow with advanced settings, including failover and VPC interfaces.

const advancedFlow = await AWS.MediaConnect.Flow("advancedMediaFlow", {
  name: "AdvancedLiveStreamFlow",
  source: {
    name: "MyAdvancedSource",
    url: "rtmp://my-advanced-source-url",
    protocol: "rtmp"
  },
  sourceFailoverConfig: {
    secondarySource: {
      name: "MySecondarySource",
      url: "rtmp://my-secondary-source-url",
      protocol: "rtmp"
    },
    failoverMode: "MANUAL"
  },
  vpcInterfaces: [
    {
      name: "VPCInterface1",
      subnetId: "subnet-12345678",
      securityGroupIds: ["sg-12345678"]
    }
  ]
});

Configuring Media Streams

Create a MediaConnect Flow that includes multiple media streams for different content types.

const mediaStreamFlow = await AWS.MediaConnect.Flow("mediaStreamFlow", {
  name: "MediaStreamFlow",
  source: {
    name: "MyStreamSource",
    url: "rtmp://my-stream-source-url",
    protocol: "rtmp"
  },
  mediaStreams: [
    {
      name: "VideoStream",
      type: "video",
      sourceType: "embedded"
    },
    {
      name: "AudioStream",
      type: "audio",
      sourceType: "embedded"
    }
  ]
});

Monitoring and Maintenance

Set up a MediaConnect Flow with monitoring and maintenance configurations.

const monitoredFlow = await AWS.MediaConnect.Flow("monitoredFlow", {
  name: "MonitoredFlow",
  source: {
    name: "MonitoredSource",
    url: "rtmp://my-monitored-source-url",
    protocol: "rtmp"
  },
  maintenance: {
    maintenanceWindowStart: "2023-10-01T00:00:00Z",
    maintenanceWindowEnd: "2023-10-01T04:00:00Z"
  },
  sourceMonitoringConfig: {
    clockRate: 90000,
    audioLevel: 0.8
  }
});
