ByteBufferGlEffect

@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

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
