java.lang.Object
  com.googlecode.mp4parser.authoring.builder.SyncSampleIntersectFinderImpl

All Implemented Interfaces:

FragmentIntersectionFinder

public class SyncSampleIntersectFinderImpl
extends Object
implements FragmentIntersectionFinder

This FragmentIntersectionFinder cuts the input movie video tracks in fragments of the same length exactly before the sync samples. Audio tracks are cut into pieces of similar length.

Constructor Summary

SyncSampleIntersectFinderImpl()

SyncSampleIntersectFinderImpl(int minFragmentDurationSeconds)
Creates a SyncSampleIntersectFinderImpl that will not create any fragment smaller than the given minFragmentDurationSeconds

Method Summary

long[]	getCommonIndices(long[] syncSamples, long[] syncSampleTimes, long timeScale, long[]... otherTracksTimes)
static List<long[]>	getSyncSamplesTimestamps(Movie movie, Track track) Calculates the timestamp of all tracks' sync samples.
long[]	sampleNumbers(Track track, Movie movie) Gets an array of sample numbers that are meant to be the first sample of each chunk or fragment.
