This effect doesn't drop any frames.

Summary

Public constructors
`SpeedChangeEffect(speed: @FloatRange(from = 0, fromInclusive = false) Float)` Creates an instance.

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

SpeedChangeEffect(speed: @FloatRange(from = 0, fromInclusive = false) Float)

Creates an instance.

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): 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.
