ColorLut

Kotlin |Java

@UnstableApi
interface ColorLut : GlEffect

Known direct subclasses

SingleColorLut

Transforms the colors of a frame by applying the same color lookup table to each frame.

Specifies color transformations using color lookup tables to apply to each frame in the fragment shader.

Summary

Public functions
`Int`	`getLength(presentationTimeUs: Long)` Returns the length N of the 3D N x N x N LUT cube with the given timestamp.
`Int`	`getLutTextureId(presentationTimeUs: Long)` Returns the OpenGL texture ID of the LUT to apply to the pixels of the frame with the given timestamp.
`Unit`	`release()` Releases the OpenGL texture of the LUT.
`GlShaderProgram!`	`toGlShaderProgram(context: Context!, useHdr: Boolean)` Returns a `GlShaderProgram` that applies the effect.

Long

getDurationAfterEffectApplied(durationUs: Long)

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

Boolean

isNoOp(inputWidth: Int, inputHeight: Int)

Returns whether a GlEffect applies no change at every timestamp.

fun getLength(presentationTimeUs: Long): Int

Returns the length N of the 3D N x N x N LUT cube with the given timestamp.

fun getLutTextureId(presentationTimeUs: Long): Int

Returns the OpenGL texture ID of the LUT to apply to the pixels of the frame with the given timestamp.

fun release(): Unit

Releases the OpenGL texture of the LUT.

Throws
`androidx.media3.common.util.GlUtil.GlException`

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

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`.
