Summary

Public fields
final long	durationUs The duration of the track sample table in microseconds.
final int[]	flags Sample flags.
final int	maximumSize Maximum sample size in sizes.
final long[]	offsets Sample offsets in bytes.
final int	sampleCount Number of samples.
final int[]	sizes Sample sizes in bytes.
final long[]	timestampsUs Sample timestamps in microseconds.
final Track	track The track corresponding to this sample table.

Public constructors
TrackSampleTable(     Track track,     long[] offsets,     int[] sizes,     int maximumSize,     long[] timestampsUs,     int[] flags,     long durationUs )

Public methods
int	getIndexOfEarlierOrEqualSynchronizationSample(long timeUs) Returns the sample index of the closest synchronization sample at or before the given timestamp, if one is available.
int	getIndexOfLaterOrEqualSynchronizationSample(long timeUs) Returns the sample index of the closest synchronization sample at or after the given timestamp, if one is available.

Public methods

getIndexOfEarlierOrEqualSynchronizationSample

public int getIndexOfEarlierOrEqualSynchronizationSample(long timeUs)

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

Parameters
long timeUs	Timestamp adjacent to which to find a synchronization sample.

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

getIndexOfLaterOrEqualSynchronizationSample

public int getIndexOfLaterOrEqualSynchronizationSample(long timeUs)

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

Parameters
long timeUs	Timestamp adjacent to which to find a synchronization sample.

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