public interface Track
extends Closeable

Represents a Track. A track is a timed sequence of related samples.
NOTE: For media data, a track corresponds to a sequence of images or sampled audio; for hint tracks, a track corresponds to a streaming channel.

Method Detail

getSampleDescriptionBox

SampleDescriptionBox getSampleDescriptionBox()

getSampleDurations

long[] getSampleDurations()

Each samples is covers a small time span in a video. This method returns the duration for each sample in track timescale. The array must contain exactly as many samples as getSamples() contains.

Returns:

an array of ticks

getDuration

long getDuration()

The duration of the track in track timescale. It's typically the sum of all samples' duration.

Returns:

the track's duration

getCompositionTimeEntries

List<CompositionTimeToSample.Entry> getCompositionTimeEntries()

getSyncSamples

long[] getSyncSamples()

getSampleDependencies

List<SampleDependencyTypeBox.Entry> getSampleDependencies()

getTrackMetaData

TrackMetaData getTrackMetaData()

getHandler

String getHandler()

getSamples

List<Sample> getSamples()

The list of all samples.

Returns:

this track's samples

getSubsampleInformationBox

SubSampleInformationBox getSubsampleInformationBox()

getName

String getName()

A name for identification purposes. Might return the underlying filename or network address or any other identifier. For informational/debug only. This is no metadata!

Returns:

the track's name

getEdits

List<Edit> getEdits()

getSampleGroups

Map<GroupEntry,long[]> getSampleGroups()
