GlEffect

Kotlin |Java

@UnstableApi
public interface GlEffect extends Effect

Known direct subclasses

`ColorLut`	Specifies color transformations using color lookup tables to apply to each frame in the fragment shader.
`Contrast`	A `GlEffect` to control the contrast of video frames.
`GlMatrixTransformation`	Specifies a 4x4 transformation `Matrix` to apply in the vertex shader for each frame.
`HslAdjustment`	Adjusts the HSL (Hue, Saturation, and Lightness) of a frame.
`RgbMatrix`	Specifies a 4x4 RGB color transformation matrix to apply to each frame in the fragment shader.

Known indirect subclasses

`Crop`	Specifies a crop to apply in the vertex shader.
`MatrixTransformation`	Specifies a 3x3 transformation `Matrix` to apply in the vertex shader for each frame.
`Presentation`	Controls how a frame is presented with options to set the output resolution and choose how to map the input pixels onto the output frame geometry (for example, by stretching the input frame to match the specified output frame, or fitting the input frame using letterboxing).
`RgbAdjustment`	Scales the red, green, and blue color channels of a frame.
`RgbFilter`	Provides common color filters.
`ScaleToFitTransformation`	Specifies a simple rotation and/or scale to apply in the vertex shader.
`SingleColorLut`	Transforms the colors of a frame by applying the same color lookup table to each frame.

Interface for a video frame effect with a GlTextureProcessor implementation.

Implementations contain information specifying the effect and can be converted to a GlTextureProcessor which applies the effect.

Summary

Public methods
`abstract GlTextureProcessor`	`toGlTextureProcessor(Context context, boolean useHdr)` Returns a `SingleFrameGlTextureProcessor` that applies the effect.

abstract GlTextureProcessor toGlTextureProcessor(Context context, boolean useHdr)

Returns a SingleFrameGlTextureProcessor 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.FrameProcessingException androidx.media3.common.FrameProcessingException`
