Class CompositionToDecodeBox

java.lang.Object

org.mp4parser.support.AbstractBox

org.mp4parser.support.AbstractFullBox

org.mp4parser.boxes.iso14496.part12.CompositionToDecodeBox

All Implemented Interfaces:

Box, FullBox, ParsableBox

public class CompositionToDecodeBox
extends AbstractFullBox

4cc = ""cslg""

The optional composition shift least greatest atom summarizes the calculated minimum and maximum offsets between decode and composition time, as well as the start and end times, for all samples. This allows a reader to determine the minimum required time for decode to obtain proper presentation order without needing to scan the sample table for the range of offsets. The type of the composition shift least greatest atom is ‘cslg’.

Method Detail

getContentSize

protected long getContentSize()

Description copied from class: AbstractBox

Get the box's content size without its header. This must be the exact number of bytes that getContent(ByteBuffer) writes.

Specified by:

getContentSize in class AbstractBox

Returns:

Gets the box's content size in bytes

See Also:

AbstractBox.getContent(java.nio.ByteBuffer)

_parseDetails

public void _parseDetails(ByteBuffer content)

Description copied from class: AbstractBox

Parse the box's fields and child boxes if any.

Specified by:

_parseDetails in class AbstractBox

Parameters:

content - the box's raw content beginning after the 4-cc field.

getContent

protected void getContent(ByteBuffer byteBuffer)

Description copied from class: AbstractBox

Write the box's content into the given ByteBuffer. This must include flags and version in case of a full box. byteBuffer has been initialized with getSize() bytes.

Specified by:

getContent in class AbstractBox

Parameters:

byteBuffer - the sink for the box's content
