@UnstableApi
interface TrackAwareSeekMap : SeekMap

A SeekMap that also allows seeking based on a specific track ID.

Summary

Public functions
`SeekMap.SeekPoints!`	`getSeekPoints(timeUs: Long, trackId: Int)` Obtains seek points for the specified seek time in microseconds, using cue points from a specific track.
`Boolean`	`isSeekable(trackId: Int)` Returns whether seeking is possible for the given track ID.

Inherited functions

From androidx.media3.extractor.SeekMap

`Long`	`getDurationUs()` Returns the duration of the stream in microseconds.
`SeekMap.SeekPoints!`	`getSeekPoints(timeUs: Long)` Obtains seek points for the specified seek time in microseconds.
`Boolean`	`isSeekable()` Returns whether seeking is supported.

Public functions

getSeekPoints

fun getSeekPoints(timeUs: Long, trackId: Int): SeekMap.SeekPoints!

Obtains seek points for the specified seek time in microseconds, using cue points from a specific track.

This method is similar to getSeekPoints, but allows specifying a trackId. The trackId is the same ID passed to track. If the given trackId does not have any associated cue points, the implementation may fall back to using a default or primary track.

Parameters
`timeUs: Long`	A seek time in microseconds.
`trackId: Int`	The ID of the track to use for finding seek points.

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

isSeekable

fun isSeekable(trackId: Int): Boolean

Returns whether seeking is possible for the given track ID.

This method is similar to isSeekable, but allows specifying a trackId. The trackId is the same ID passed to track.

Parameters
`trackId: Int`	The ID of the track.

Returns
`Boolean`	Whether seeking is possible for the track.
