Struct CameraPipeline

Source

pub struct CameraPipeline {
    cancel: Arc<AtomicBool>,
    handle: Option<JoinHandle<()>>,
}

Expand description

Camera-pipeline worker handle. Owns the spawned thread and a cooperative cancel flag; Drop cancels + joins so a panicking caller can never leave a zombie gst child behind.

Fields§

§cancel: Arc<AtomicBool>§handle: Option<JoinHandle<()>>

Implementations§

Source §

impl CameraPipeline

Source

pub fn spawn(app: AppHandle, camera_id: String) -> Result<Self, CameraError>

Spawn the worker thread for the camera identified by camera_id (M-CAM.4 — was hard-coded to the OS default device in M-CAM.3). Returns immediately; the worker transitions the preview lifecycle to Running once next_frame() succeeds (after any macOS permission prompt resolves). An empty camera_id keeps the legacy “OS default” behaviour so the picker can start without a selection.

§Errors

Returns Err only if the OS refuses to spawn a thread (which effectively never happens). gst-side errors are handled inside the worker — the worker logs via tracing::error! and advances the lifecycle back to Idle so the UI shows a recovery state.
