Summary

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

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

IntArray<Int>!	flags Sample flags.
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.
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.
