TimestampAdjustment

Kotlin |Java

@UnstableApi
public final class TimestampAdjustment implements GlEffect

Changes the frame timestamps using the TimestampMap.

This effect doesn't drop any frames.

Summary

Nested types
`public interface TimestampAdjustment.TimestampMap` Maps input timestamps to output timestamps asynchronously.

Public fields
`final SpeedProvider`	`speedProvider`
`final TimestampAdjustment.TimestampMap`	`timestampMap`

Public constructors
`TimestampAdjustment( TimestampAdjustment.TimestampMap timestampMap, SpeedProvider speedProvider )` Creates an instance.

Public methods
`long`	`getDurationAfterEffectApplied(long durationUs)` Returns the expected duration of the output stream when the effect is applied given a input `durationUs`.
`GlShaderProgram`	`toGlShaderProgram(Context context, boolean useHdr)` Returns a `GlShaderProgram` that applies the effect.

boolean

isNoOp(int inputWidth, int inputHeight)

Returns whether a GlEffect applies no change at every timestamp.

public final SpeedProvider speedProvider

public final TimestampAdjustment.TimestampMap timestampMap

public TimestampAdjustment(
    TimestampAdjustment.TimestampMap timestampMap,
    SpeedProvider speedProvider
)

Creates an instance.

Parameters
`TimestampAdjustment.TimestampMap timestampMap`	The `TimestampMap`
`SpeedProvider speedProvider`	The `SpeedProvider` specifying the approximate speed adjustments the `TimestampMap` should be applying.

public long getDurationAfterEffectApplied(long durationUs)

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

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`.
