Plugin Interfaces

The Core module defines interfaces for creating plugins that extend camera functionality.

CameraPlugin

The base interface for all plugins.

interface CameraPlugin {
    val id: String
    fun onAttach(controller: CameraController)
    fun onDetach()
}

FrameAnalyzerPlugin<T>

A plugin that processes image frames from the camera preview stream (e.g., for ML analysis).

interface FrameAnalyzerPlugin<T> : CameraPlugin {
    // Returns a Flow of results
    fun analyze(frame: CameraFrame): Flow<T>

    fun start()
    fun stop()
    val isRunning: Boolean
}

CameraFrame

Represents a single frame to be processed.

• data: Raw byte array.
• width: Frame width.
• height: Frame height.
• format: Pixel format (e.g., NV21, YUV_420_888).
• rotation: Image rotation in degrees.
• timestamp: Capture timestamp.
• nativeImage: Platform-specific image object (ImageProxy on Android, CMSampleBuffer on iOS).

ImageCapturePlugin

A plugin that intercepts captured images.

interface ImageCapturePlugin : CameraPlugin {
    fun onImageCaptured(imageData: ByteArray, width: Int, height: Int)
}
