Interface: UseVisionCameraSourceOptions

Defined in: react-native-vision-camera-source/src/useVisionCameraSource.ts:24

Options for useVisionCameraSource. Also accepts every VisionCamera frame-output option (targetResolution, pixelFormat, dropFramesWhileBusy, and so on) and passes it through.

Properties

enabled?

optional enabled: boolean

Defined in: react-native-vision-camera-source/src/useVisionCameraSource.ts:29

Whether the source is live. While false, no track exists and nothing is published — the declarative sibling of VisionCamera's isActive. Defaults to true.

---

frameIntervalNanoseconds?

optional frameIntervalNanoseconds: number

Defined in: react-native-vision-camera-source/src/useVisionCameraSource.ts:46

Fallback spacing between published frames, in nanoseconds, used only when a camera frame carries no usable timestamp. Defaults to 33,333,333 (30 fps).

---

onFrame()?

optional onFrame: (frame) => void

Defined in: react-native-vision-camera-source/src/useVisionCameraSource.ts:39

Optional worklet called with every camera frame, after the frame has been sent to Fishjam — run your frame-processor plugins (pose detection, OCR, …) here.

The frame is valid only for the duration of this synchronous callback; the hook releases it when the callback returns, so do not retain it. Keep the function's identity stable (useCallback or module scope) — a new function every render forces VisionCamera to re-register the frame callback.

Parameters

Parameter	Type
frame	Frame

Returns

void

onFrameDropped()?

optional onFrameDropped: (reason) => void

Defined in: react-native-vision-camera-source/src/useVisionCameraSource.ts:41

Called whenever the camera pipeline drops a frame; forwarded to VisionCamera.

Parameters

Parameter	Type
reason	FrameDroppedReason

Returns

void
