class TrackSampleTable

Sample table for a track in an MP4 file.

Summary

Public constructors
`TrackSampleTable( track: Track!, offsets: LongArray!, sizes: IntArray!, maximumSize: Int, timestampsUs: LongArray!, flags: IntArray!, syncSampleIndices: IntArray!, hasOnlySyncSamples: Boolean, durationUs: Long, sampleCount: Int )`

Public functions
`Int`	`getIndexOfEarlierOrEqualSynchronizationSample(timeUs: Long)` Returns the sample index of the closest synchronization sample at or before the given timestamp, if one is available.
`Int`	`getIndexOfLaterOrEqualSynchronizationSample(timeUs: Long)` Returns the sample index of the closest synchronization sample at or after the given timestamp, if one is available.

Public properties
`Long`	`durationUs` The duration of the track sample table in microseconds.
`IntArray<Int>!`	`flags` Sample flags.
`Boolean`	`hasOnlySyncSamples` Whether all samples in the track are sync samples.
`Int`	`maximumSize` Maximum sample size in `sizes`.
`LongArray<Long>!`	`offsets` Sample offsets in bytes.
`Int`	`sampleCount` Number of samples.
`IntArray<Int>!`	`sizes` Sample sizes in bytes.
`IntArray<Int>!`	`syncSampleIndices` The indices of sync samples, sorted in ascending order.
`LongArray<Long>!`	`timestampsUs` Sample timestamps in microseconds.
`Track!`	`track` The track corresponding to this sample table.

Public functions

getIndexOfEarlierOrEqualSynchronizationSample

fun getIndexOfEarlierOrEqualSynchronizationSample(timeUs: Long): Int

Returns the sample index of the closest synchronization sample at or before the given timestamp, if one is available.

Parameters
`timeUs: Long`	Timestamp adjacent to which to find a synchronization sample.

Returns
`Int`	Index of the synchronization sample, or `INDEX_UNSET` if none.

getIndexOfLaterOrEqualSynchronizationSample

fun getIndexOfLaterOrEqualSynchronizationSample(timeUs: Long): Int

Returns the sample index of the closest synchronization sample at or after the given timestamp, if one is available.

Parameters
`timeUs: Long`	Timestamp adjacent to which to find a synchronization sample.

Returns
`Int`	index Index of the synchronization sample, or `INDEX_UNSET` if none.

Public properties

durationUs

val durationUs: Long

The duration of the track sample table in microseconds.

flags

val flags: IntArray<Int>!

Sample flags.

hasOnlySyncSamples

val hasOnlySyncSamples: Boolean

Whether all samples in the track are sync samples.

maximumSize

val maximumSize: Int

Maximum sample size in sizes.

offsets

val offsets: LongArray<Long>!

Sample offsets in bytes.

sampleCount

val sampleCount: Int

Number of samples.

sizes

val sizes: IntArray<Int>!

Sample sizes in bytes.

syncSampleIndices

val syncSampleIndices: IntArray<Int>!

The indices of sync samples, sorted in ascending order. This array is only populated if hasOnlySyncSamples is false.

timestampsUs

val timestampsUs: LongArray<Long>!

Sample timestamps in microseconds.

track

val track: Track!

The track corresponding to this sample table.
