struct CameraAvStreamManagementTrait This trait provides an interface for managing active audio and video streams on a camera device. This is a minimalistic custom version of the CameraAvStreamManagement standard Matter cluster, and provides functionality for some of the camera settings. - ` ### [supportedEventTypes](https://developers.home.google.com/reference/swift/GoogleHomeTypes/Enums/Matter/CameraAvStreamManagementTrait#/s:15GoogleHomeTypes6MatterO29CameraAvStreamManagementTraitV014supportedEventC0Say0aB3SDK0K0_pXpGvpZ) ` No supported events for `CameraAvStreamManagementTrait`. #### Declaration Swift static let supportedEventTypes: [any Event.Type] - ` ### [supportedCommandTypes](https://developers.home.google.com/reference/swift/GoogleHomeTypes/Enums/Matter/CameraAvStreamManagementTrait#/s:15GoogleHomeTypes6MatterO29CameraAvStreamManagementTraitV016supportedCommandC0Say0aB3SDK0K0_pXpGvpZ) ` List of the commands that are supported by `CameraAvStreamManagementTrait`. #### Declaration Swift static let supportedCommandTypes: [any Command.Type] - ` ### [identifier](https://developers.home.google.com/reference/swift/GoogleHomeTypes/Enums/Matter/CameraAvStreamManagementTrait#/s:15GoogleHomeTypes6MatterO29CameraAvStreamManagementTraitV10identifierSSvpZ) ` The trait identifier. #### Declaration Swift static let identifier: String - ` ### [metadata](https://developers.home.google.com/reference/swift/GoogleHomeTypes/Enums/Matter/CameraAvStreamManagementTrait#/s:15GoogleHomeTypes6MatterO29CameraAvStreamManagementTraitV8metadata0aB3SDK0I8MetadataVvp) ` Metadata about this `Trait`. #### Declaration Swift let metadata: TraitMetadata - ` ### [attributes](https://developers.home.google.com/reference/swift/GoogleHomeTypes/Enums/Matter/CameraAvStreamManagementTrait#/s:15GoogleHomeTypes6MatterO29CameraAvStreamManagementTraitV10attributesAE10AttributesVvp) ` List of attributes for the `CameraAvStreamManagementTrait`. #### Declaration Swift let attributes: https://developers.home.google.com/reference/swift/GoogleHomeTypes/Enums/Matter.html.CameraAvStreamManagementTrait.https://developers.home.google.com/reference/swift/GoogleHomeTypes/Enums/Matter/CameraAvStreamManagementTrait/Attributes.html - ` ### [init(decoder:interactionProxy:metadata:)](https://developers.home.google.com/reference/swift/GoogleHomeTypes/Enums/Matter/CameraAvStreamManagementTrait#/s:15GoogleHomeTypes6MatterO29CameraAvStreamManagementTraitV7decoder16interactionProxy8metadataAE0aB3SDK0I7DecoderV_AI011InteractionL0_pSgAI0I8MetadataVtKcfc) ` Creates a new Trait instance using data read from the given `TraitDecoder`.
