NativeThreadFactory

interface NativeThreadFactory extends HybridObject

A factory for creating NativeThreads.

Typically you would never need this as Camera Outputs create NativeThreads.

You can create NativeThreads for advanced asynchronous processing on a Worklet Queue, in which case VisionCamera prepares the necessary setup such as installing a Dispatcher to your Worklet Runtime.

Methods

createNativeThread()

createNativeThread(name: string): NativeThread

Create a new NativeThread.

A NativeThread can be used for Camera operations such as Frame Processing. It uses platform native dispatching mechanisms like DispatchQueue or CoroutineContext.

You can use the WorkletQueueFactory from react-native-vision-camera-worklets to wrap the NativeThread in a WorkletQueue, which allows you to run JS code on the thread.

Example

Creating a Worklet Runtime using this NativeThread:

const thread = NativeThreadFactory.createNativeThread('async-processor')
const runtime = createWorkletRuntimeForThread(thread)
