HslAdjustment

Kotlin |Java

@UnstableApi
class HslAdjustment : GlEffect

Adjusts the HSL (Hue, Saturation, and Lightness) of a frame.

Summary

Nested types
`class HslAdjustment.Builder` A builder for `HslAdjustment` instances.

Public functions
`Boolean`	`isNoOp(inputWidth: Int, inputHeight: Int)` Returns whether a `GlEffect` applies no change at every timestamp.
`BaseGlShaderProgram!`	`toGlShaderProgram(context: Context!, useHdr: Boolean)` Returns a `GlShaderProgram` that applies the effect.

Public properties
`Float`	`hueAdjustmentDegrees` Indicates the hue adjustment in degrees.
`Float`	`lightnessAdjustment` Indicates the lightness adjustment.
`Float`	`saturationAdjustment` Indicates the saturation adjustment.

Long

getDurationAfterEffectApplied(durationUs: Long)

Returns the expected duration of the output stream when the effect is applied given a input durationUs.

fun isNoOp(inputWidth: Int, inputHeight: Int): Boolean

Returns whether a GlEffect applies no change at every timestamp.

This can be used as a hint to skip this instance.

Parameters
`inputWidth: Int`	The input frame width, in pixels.
`inputHeight: Int`	The input frame height, in pixels.

fun toGlShaderProgram(context: Context!, useHdr: Boolean): BaseGlShaderProgram!

Returns a GlShaderProgram that applies the effect.

Parameters
`context: Context!`	A `Context`.
`useHdr: Boolean`	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 `GlShaderProgram`.

val hueAdjustmentDegrees: Float

Indicates the hue adjustment in degrees.

val lightnessAdjustment: Float
