public SpeedChangeEffect(@FloatRange(from = 0, fromInclusive = false) float speed)

Creates an instance that applies the same speed change to all the timestamps.

public SpeedChangeEffect(SpeedProvider speedProvider)

Creates an instance.

Parameters
`SpeedProvider speedProvider`	The `SpeedProvider` specifying the speed changes. Applied on each stream assuming the first frame timestamp of the input media is 0.

public long getDurationAfterEffectApplied(long durationUs)

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

public boolean isNoOp(int inputWidth, int inputHeight)

Returns whether a GlEffect applies no change at every timestamp.

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

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

public GlShaderProgram toGlShaderProgram(Context context, boolean useHdr)

Returns a GlShaderProgram 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.VideoFrameProcessingException`	If an error occurs while creating the `GlShaderProgram`.
