Struct libcamera::camera::Camera

pub struct Camera<'d> { /* private fields */ }

A read-only instance of a camera.

Can be used to obtain camera parameters or supported stream configurations. In order to be used for capturing, it must be turned into an ActiveCamera by Camera::acquire().

Implementations

impl<'d> Camera<'d>

pub fn id(&self) -> &str

ID of the camera.

This usually contains hardware path within the system and is not human-friendly. Use properties::Model from Camera::properties() to obtain a human readable identification instead.

pub fn controls(&self) -> &ControlInfoMap

Returns a list of available camera controls and their limit.

pub fn properties(&self) -> &PropertyList

Returns a list of camera properties.

See properties for available items.

pub fn generate_configuration( &self, roles: &[StreamRole], ) -> Option<CameraConfiguration>

Generates default camera configuration for the given StreamRoles.

The resulting CameraConfiguration contains stream configurations for each of the requested roles.

Generated configuration can be adjusted as needed and then passed onto ActiveCamera::configure() to apply.

pub fn acquire(&self) -> Result<ActiveCamera<'_>>

Acquires exclusive rights to the camera, which allows changing configuration and capturing.

Trait Implementations

impl<'d> Drop for Camera<'d>

fn drop(&mut self)

Executes the destructor for this type.
