Field Detail

mediaType

protected final FormatKeys.MediaType mediaType

The media type of the track.

format

protected Format format

The format of the media in the track.

mediaTimeScale

protected long mediaTimeScale

The timeScale of the media in the track. A time value that indicates the time scale for this media. That is, the number of time units that pass per second in its time coordinate system.

mediaCompressionType

protected String mediaCompressionType

The compression type of the media.

mediaCompressorName

protected String mediaCompressorName

The compressor name.

chunks

protected ArrayList<AbstractQuickTimeStream.Chunk> chunks

List of chunks.

timeToSamples

protected ArrayList<AbstractQuickTimeStream.TimeToSampleGroup> timeToSamples

List of TimeToSample entries.

sampleSizes

protected ArrayList<AbstractQuickTimeStream.SampleSizeGroup> sampleSizes

List of SampleSize entries.

syncSamples

protected ArrayList<Long> syncSamples

List of sync samples. This list is null as long as all samples in this track are sync samples.

sampleCount

protected long sampleCount

The number of samples in this track.

mediaDuration

protected long mediaDuration

The duration of the media in this track in media time units.

editList

protected AbstractQuickTimeStream.Edit[] editList

The edit list of the track.

syncInterval

protected int syncInterval

Interval between sync samples (keyframes). 0 = automatic. 1 = write all samples as sync samples. n = sync every n-th sample.

codec

protected Codec codec

The codec.
