Constructor Detail

Mp4TrackImpl

public Mp4TrackImpl(long trackId,
                    Container isofile,
                    RandomAccessSource randomAccess,
                    String name)

Creates a track from a TrackBox and potentially fragments. Use fragements parameter only to supply additional fragments that are not located in the main file.

Parameters:

trackId - ID of the track to extract

isofile - the parsed MP4 file

randomAccess - the RandomAccessSource to read the samples from

name - an arbitrary naem to identify track later - e.g. filename

Method Detail

close

public void close()
           throws IOException

Throws:

IOException

getSamples

public List<Sample> getSamples()

Description copied from interface: Track

The list of all samples.

Returns:

this track's samples

getSampleDurations

public long[] getSampleDurations()

Description copied from interface: Track

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 Track.getSamples() contains.

Returns:

an array of ticks
