@UnstableApi
class IndexSeekMap : SeekMap

A SeekMap implementation based on a mapping between times and positions in the input stream.

Summary

Public constructors
`IndexSeekMap(positions: LongArray!, timesUs: LongArray!, durationUs: Long)` Creates an instance.

Public functions
`SeekMap.SeekPoints!`	`getSeekPoints(timeUs: Long)` Obtains seek points for the specified seek time in microseconds.

Public properties
`Long`	`durationUs`
`Boolean`	`isSeekable`

Public constructors

IndexSeekMap

IndexSeekMap(positions: LongArray!, timesUs: LongArray!, durationUs: Long)

Creates an instance.

Parameters
`positions: LongArray!`	The positions in the stream corresponding to `timesUs`, in bytes.
`timesUs: LongArray!`	The times corresponding to `positions`, in microseconds.
`durationUs: Long`	The duration of the input stream, or `TIME_UNSET` if it is unknown.

Public functions

getSeekPoints

fun getSeekPoints(timeUs: Long): SeekMap.SeekPoints!

Obtains seek points for the specified seek time in microseconds. The returned will contain one or two distinct seek points.

Two seek points [A, B] are returned in the case that seeking can only be performed to discrete points in time, there does not exist a seek point at exactly the requested time, and there exist seek points on both sides of it. In this case A and B are the closest seek points before and after the requested time. A single seek point is returned in all other cases.

Parameters
`timeUs: Long`	A seek time in microseconds.

Returns
`SeekMap.SeekPoints!`	The corresponding seek points.

Public properties
