A Device represents a unique physical camera present in the system. Only one client may connect to an unbound physical camera, however the “Rebind” method can be used to create multiple connections to it to be used by a coordinated set of clients.

Variants

GetIdentifier

Returns an identifier for the camera. If present, identical devices on different systems will have the same identifier. Clients may use this to determine if additional semantics known a priori for a given device apply to the current camera.

Fields

responder: DeviceGetIdentifierResponder

GetConfigurations

Returns a list of configurations supported by the camera. All cameras will have at least one configuration. The values returned are immutable - they will not change for the lifetime of the client’s connection to the Camera.

Fields

responder: DeviceGetConfigurationsResponder

GetConfigurations2

Returns a list of configurations supported by the camera. All cameras will have at least one configuration. The values returned are immutable - they will not change for the lifetime of the client’s connection to the Camera.

Fields

responder: DeviceGetConfigurations2Responder

WatchCurrentConfiguration

Returns the index of the current configuration when it has changed from a previously returned configuration, or is called by a client for the first time.

Fields

responder: DeviceWatchCurrentConfigurationResponder

SetCurrentConfiguration

Sets the configuration using the provided index. Calling this method disconnects any existing Stream clients associated with this camera. An epitaph of ZX_OK will be sent for any connected Stream clients on closing.

Fields

index: u32

control_handle: DeviceControlHandle

WatchMuteState

Returns the camera’s current mute state when it has changed from a previously returned state, or is called by a client for the first time. A camera may be muted using SetSoftwareMuteState or by a physical switch. If either muted mode is active, stream clients associated with this physical camera will stop receiving new frames.

Fields

responder: DeviceWatchMuteStateResponder

SetSoftwareMuteState

Sets the current camera’s software mute state. When transitioning to the muted state, this method returns when the camera has successfully ceased sending new frames to stream clients. When transitioning to the unmuted state, this method returns immediately.

Fields

muted: bool

responder: DeviceSetSoftwareMuteStateResponder

ConnectToStream

Connects to the Stream at the provided index. If any clients already exist for this stream, the request is closed with the ZX_ERR_ALREADY_BOUND epitaph.

Fields

index: u32

request: ServerEnd<Stream_Marker>

control_handle: DeviceControlHandle

Rebind

Request another connection to this Device. This allows a client to delegate different operations to different coordinated clients.

Fields

request: ServerEnd<DeviceMarker>

control_handle: DeviceControlHandle
