Implements IConstruct, IDependable, IInspectable, ITaggable

The AWS::IVS::Channel resource specifies an channel.

A channel stores configuration information related to your live stream. For more information, see CreateChannel in the Amazon IVS Low-Latency Streaming API Reference .

By default, the IVS API CreateChannel endpoint creates a stream key in addition to a channel. The Channel resource does not create a stream key; to create a stream key, use the StreamKey resource instead.

Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_ivs as ivs } from 'aws-cdk-lib';
const cfnChannel = new ivs.CfnChannel(this, 'MyCfnChannel', /* all optional props */ {
  authorized: false,
  insecureIngest: false,
  latencyMode: 'latencyMode',
  name: 'name',
  preset: 'preset',
  recordingConfigurationArn: 'recordingConfigurationArn',
  tags: [{
    key: 'key',
    value: 'value',

Construct Props

Name	Type	Description
authorized?	`boolean \|` `IResolvable`	Whether the channel is authorized.
insecureIngest?	`boolean \|` `IResolvable`	Whether the channel allows insecure RTMP ingest.
latencyMode?	`string`	Channel latency mode. Valid values:.
name?	`string`	Channel name.
preset?	`string`	An optional transcode preset for the channel.
recordingConfigurationArn?	`string`	The ARN of a RecordingConfiguration resource.
tags?	`CfnTag[]`	An array of key-value pairs to apply to this resource.
type?	`string`	The channel type, which determines the allowable resolution and bitrate.

authorized?

Type: boolean | IResolvable (optional, default: false)

Whether the channel is authorized.

Default : false

insecureIngest?

Type: boolean | IResolvable (optional, default: false)

Whether the channel allows insecure RTMP ingest.

Default : false

latencyMode?

Type: string (optional, default: "LOW")

Channel latency mode. Valid values:.

NORMAL : Use NORMAL to broadcast and deliver live video up to Full HD.
LOW : Use LOW for near real-time interactions with viewers.

In the console, LOW and NORMAL correspond to Ultra-low and Standard , respectively.

Default : LOW

name?

Type: string (optional, default: "-")

Channel name.

preset?

Type: string (optional)

An optional transcode preset for the channel.

This is selectable only for ADVANCED_HD and ADVANCED_SD channel types. For those channel types, the default preset is HIGHER_BANDWIDTH_DELIVERY . For other channel types ( BASIC and STANDARD ), preset is the empty string ("").

recordingConfigurationArn?

Type: string (optional, default: "")

The ARN of a RecordingConfiguration resource.

An empty string indicates that recording is disabled for the channel. A RecordingConfiguration ARN indicates that recording is enabled using the specified recording configuration. See the RecordingConfiguration resource for more information and an example.

Default : "" (empty string, recording is disabled)

tags?

Type: CfnTag[] (optional)

An array of key-value pairs to apply to this resource.

For more information, see Tag .

type?

Type: string (optional, default: "STANDARD")

The channel type, which determines the allowable resolution and bitrate.

If you exceed the allowable resolution or bitrate, the stream probably will disconnect immediately. Valid values:

STANDARD : Video is transcoded: multiple qualities are generated from the original input to automatically give viewers the best experience for their devices and network conditions. Transcoding allows higher playback quality across a range of download speeds. Resolution can be up to 1080p and bitrate can be up to 8.5 Mbps. Audio is transcoded only for renditions 360p and below; above that, audio is passed through.
BASIC : Video is transmuxed: Amazon IVS delivers the original input to viewers. The viewer’s video-quality choice is limited to the original input. Resolution can be up to 1080p and bitrate can be up to 1.5 Mbps for 480p and up to 3.5 Mbps for resolutions between 480p and 1080p.
ADVANCED_SD : Video is transcoded; multiple qualities are generated from the original input, to automatically give viewers the best experience for their devices and network conditions. Input resolution can be up to 1080p and bitrate can be up to 8.5 Mbps; output is capped at SD quality (480p). You can select an optional transcode preset (see below). Audio for all renditions is transcoded, and an audio-only rendition is available.
ADVANCED_HD : Video is transcoded; multiple qualities are generated from the original input, to automatically give viewers the best experience for their devices and network conditions. Input resolution can be up to 1080p and bitrate can be up to 8.5 Mbps; output is capped at HD quality (720p). You can select an optional transcode preset (see below). Audio for all renditions is transcoded, and an audio-only rendition is available.

Optional transcode presets (available for the ADVANCED types) allow you to trade off available download bandwidth and video quality, to optimize the viewing experience. There are two presets:

Constrained bandwidth delivery uses a lower bitrate for each quality level. Use it if you have low download bandwidth and/or simple video content (e.g., talking heads)
Higher bandwidth delivery uses a higher bitrate for each quality level. Use it if you have high download bandwidth and/or complex video content (e.g., flashes and quick scene changes).

Default : STANDARD

addDeletionOverride(path)

public addDeletionOverride(path: string): void

Parameters

path string — The path of the value to delete.

Syntactic sugar for addOverride(path, undefined).

addDependency(target)

public addDependency(target: CfnResource): void

Parameters

target CfnResource

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

addDependsOn(target)⚠️

public addDependsOn(target: CfnResource): void

⚠️ Deprecated: use addDependency

Parameters

target CfnResource

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

addMetadata(key, value)

public addMetadata(key: string, value: any): void

Parameters

key string
value any

Add a value to the CloudFormation Resource Metadata.

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.)

addOverride(path, value)

public addOverride(path: string, value: any): void

Parameters

path string — - The path of the property, you can use dot notation to override values in complex types.
value any — - The value.

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with "Properties." (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example,

cfnResource.addOverride('Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes', ['myattribute']);
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.1.ProjectionType', 'INCLUDE');

would add the overrides

"Properties": {
  "GlobalSecondaryIndexes": [
    {
      "Projection": {
        "NonKeyAttributes": [ "myattribute" ]
        ...
      }
      ...
    },
    {
      "ProjectionType": "INCLUDE"
      ...
    },
  ]
  ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.

addPropertyDeletionOverride(propertyPath)

public addPropertyDeletionOverride(propertyPath: string): void

Parameters

propertyPath string — The path to the property.

Adds an override that deletes the value of a property from the resource definition.

addPropertyOverride(propertyPath, value)

public addPropertyOverride(propertyPath: string, value: any): void

Parameters

propertyPath string — The path of the property.
value any — The value.

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

applyRemovalPolicy(policy?, options?)

public applyRemovalPolicy(policy?: RemovalPolicy, options?: RemovalPolicyOptions): void

Parameters

policy RemovalPolicy
options RemovalPolicyOptions

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you've removed it from the CDK application or because you've made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN). In some cases, a snapshot can be taken of the resource prior to deletion (RemovalPolicy.SNAPSHOT). A list of resources that support this policy can be found in the following link:

getAtt(attributeName, typeHint?)

public getAtt(attributeName: string, typeHint?: ResolutionTypeHint): Reference

Parameters

attributeName string — The name of the attribute.
typeHint ResolutionTypeHint

Returns

Reference

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

getMetadata(key)

public getMetadata(key: string): any

Parameters

key string

Returns

any

Retrieve a value value from the CloudFormation Resource Metadata.

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.)

inspect(inspector)

public inspect(inspector: TreeInspector): void

Parameters

inspector TreeInspector — tree inspector to collect and process attributes.

Examines the CloudFormation resource and discloses attributes.

obtainDependencies()

public obtainDependencies(): Stack &#124; CfnResource[]

Returns

Stack | CfnResource[]

Retrieves an array of resources this resource depends on.

This assembles dependencies on resources across stacks (including nested stacks) automatically.

obtainResourceDependencies()

public obtainResourceDependencies(): CfnResource[]

Returns

CfnResource[]

Get a shallow copy of dependencies between this resource and other resources in the same stack.

overrideLogicalId(newLogicalId)

public overrideLogicalId(newLogicalId: string): void

Parameters

Overrides the auto-generated logical ID with a specific ID.

removeDependency(target)

public removeDependency(target: CfnResource): void

Parameters

target CfnResource

This can be used for resources across stacks (including nested stacks) and the dependency will automatically be removed from the relevant scope.

replaceDependency(target, newTarget)

public replaceDependency(target: CfnResource, newTarget: CfnResource): void

Parameters

target CfnResource — The dependency to replace.
newTarget CfnResource — The new dependency to add.

Replaces one dependency with another.

toString()

public toString(): string
