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

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
insecure_ingest (
Union
[bool
,IResolvable
,None
]) – Whether the channel allows insecure RTMP ingest. 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
andNORMAL
correspond toUltra-low
andStandard
, 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
: 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. 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:
- Return type:
None
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.
- add_override(path, value)
Adds an override to the synthesized CloudFormation resource.
To add a property override, either use
addPropertyOverride
or prefixpath
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 toaddOverride
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: truedefault (
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:
- get_metadata(key)
Retrieve a value value from the CloudFormation Resource Metadata.
- Parameters:
key (
str
)- See:
- Return type:
Any
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)
Examines the CloudFormation resource and discloses attributes.
- Parameters:
inspector (
TreeInspector
) –tree inspector to collect and process attributes.
- Return type:
None
- override_logical_id(new_logical_id)
Overrides the auto-generated logical ID with a specific ID.
- Parameters:
new_logical_id (
str
) – The new logical ID to use for this stack element.- Return type:
None
- to_string()
Returns a string representation of this construct.
- Return type:
str
- Returns:
a string representation of this resource

Channel latency mode. Valid values
- logical_id
The logical ID for this CloudFormation stack element.
The logical ID of the element is calculated from the path of the resource node in the construct tree.
