CfnChannel

class aws_cdk.aws_ivs.CfnChannel(scope, id, *, authorized=None, latency_mode=None, name=None, recording_configuration_arn=None, tags=None, type=None)

Bases: aws_cdk.core.CfnResource

A CloudFormation AWS::IVS::Channel.

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 Interactive Video Service API Reference . .. epigraph:

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_cdk.aws_ivs as ivs

cfn_channel = ivs.CfnChannel(self, "MyCfnChannel",
    authorized=False,
    latency_mode="latencyMode",
    name="name",
    recording_configuration_arn="recordingConfigurationArn",
    tags=[CfnTag(
        key="key",
        value="value"
    )],
    type="type"
)

Create a new AWS::IVS::Channel.

Parameters
  • scope (Construct) –

    • scope in which this resource is defined.

  • id (str) –

    • scoped id of the resource.

  • authorized (Union[bool, IResolvable, None]) – Whether the channel is authorized. Default : false

  • latency_mode (Optional[str]) – 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. .. epigraph:: In the console, LOW and NORMAL correspond to Ultra-low and Standard , respectively. Default : LOW

  • name (Optional[str]) – Channel name.

  • recording_configuration_arn (Optional[str]) – 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 (Optional[Sequence[Union[CfnTag, Dict[str, Any]]]]) – An array of key-value pairs to apply to this resource. For more information, see Tag .

  • type (Optional[str]) – 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 : Multiple qualities are generated from the original input, to automatically give viewers the best experience for their devices and network conditions. 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 : delivers the original input to viewers. The viewer’s video-quality choice is limited to the original input. Resolution can be up to 480p and bitrate can be up to 1.5 Mbps. Default : STANDARD

Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters

path (str) – The path of the value to delete.

Return type

None

add_depends_on(target)

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.

Parameters

target (CfnResource) –

Return type

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters
  • key (str) –

  • value (Any) –

See

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.

Return type

None

add_override(path, 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:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"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.

Parameters
  • path (str) –

    • The path of the property, you can use dot notation to override values in complex types. Any intermdediate keys will be created as needed.

  • value (Any) –

    • The value. Could be primitive or complex.

Return type

None

add_property_deletion_override(property_path)

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

Parameters

property_path (str) – The path to the property.

Return type

None

add_property_override(property_path, value)

Adds an override to a resource property.

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

Parameters
  • property_path (str) – The path of the property.

  • value (Any) – The value.

Return type

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

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).

Parameters
  • policy (Optional[RemovalPolicy]) –

  • apply_to_update_replace_policy (Optional[bool]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: true

  • default (Optional[RemovalPolicy]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resoure, please consult that specific resource’s documentation.

Return type

None

get_att(attribute_name)

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.

Parameters

attribute_name (str) – The name of the attribute.

Return type

Reference

get_metadata(key)

Retrieve a value value from the CloudFormation Resource Metadata.

Parameters

key (str) –

See

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.

Return type

Any

inspect(inspector)
