abstract class BackedBySurfaceTexture(val surfaceTexture: SurfaceTexture) : ImageProcessor.Input

Convenience base Input that is backed by android.graphics.SurfaceTexture.

Constructors

BackedBySurfaceTexture

constructor(surfaceTexture: SurfaceTexture)

Properties

abstract val facingFront: Boolean

True indicates whether a Frame is facing front in relation to user that is observing it.

abstract val height: Int

The expected height in pixels of a Frame that is read once available.

rotationDegrees

abstract val rotationDegrees: Int

The natural orientation of a Frame in relation to a device that is providing it.

open val surfaceTexture: SurfaceTexture

abstract val width: Int

Functions

attachToGlContext

abstract fun attachToGlContext(textureId: Int)

Mirrors android.graphics.SurfaceTexture.attachToGLContext when this input is backed by android.graphics.SurfaceTexture.

detachFromGlContext

abstract fun detachFromGlContext()

Mirrors android.graphics.SurfaceTexture.detachFromGLContext when this input is backed by android.graphics.SurfaceTexture.

abstract fun readFrame(): ImageProcessor.Input.Frame

Allows to read a Frame when notified by in a callback subscribed via subscribeTo.

abstract fun subscribeTo(onFrameAvailable: Consumer<ImageProcessor.Input>): Closeable

Subscribes to the provided onFrameAvailable to be notified when a new Frame is available for this input. The returned Closeable must be closed when done working with this input otherwise underlying resources will be leaked.
