@UnstableApi
public class ByteBufferGlEffect<T> implements GlEffect

---

A GlEffect implementation that runs an asynchronous Processor on video frame data passed in as a ByteBufferGlEffect.Image.

This effect can be used to apply CPU-based effects. Or the provided can be passed to other heterogeneous compute components that are available such as another GPU context, FPGAs, or NPUs.

Summary

Nested types
public class ByteBufferGlEffect.Image A class that represents image data is backed by a ByteBuffer.
public interface ByteBufferGlEffect.Processor<T> A processor that takes in ByteBuffers that represent input image data, and produces results of type <T>.

Public constructors
ByteBufferGlEffect(ByteBufferGlEffect.Processor<T> processor) Creates an instance.

Public methods
GlShaderProgram	toGlShaderProgram(Context context, boolean useHdr) Returns a GlShaderProgram that applies the effect.

Inherited methods
From androidx.media3.common.Effect long getDurationAfterEffectApplied(long durationUs) Returns the expected duration of the output stream when the effect is applied given a input durationUs.
From androidx.media3.effect.GlEffect boolean isNoOp(int inputWidth, int inputHeight) Returns whether a GlEffect applies no change at every timestamp.

Public constructors

ByteBufferGlEffect

public ByteBufferGlEffect(ByteBufferGlEffect.Processor<T> processor)

Creates an instance.

Parameters
ByteBufferGlEffect.Processor<T> processor	The effect to apply.

Public methods

toGlShaderProgram

public GlShaderProgram toGlShaderProgram(Context context, boolean useHdr)

Returns a GlShaderProgram that applies the effect.

Parameters
Context context	A Context.
boolean useHdr	Whether input textures come from an HDR source. If true, colors will be in linear RGB BT.2020. If false, colors will be in linear RGB BT.709.

Throws
androidx.media3.common.VideoFrameProcessingException	If an error occurs while creating the .
