          extended by com.coremedia.iso.boxes.CompositionShiftLeastGreatestAtom
All Implemented Interfaces:
Box, FullBox

public class CompositionShiftLeastGreatestAtom
extends AbstractFullBox

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’.

Constructor Detail

CompositionShiftLeastGreatestAtom

public CompositionShiftLeastGreatestAtom()
Method Detail

getContentSize

protected long getContentSize()
Description copied from class: AbstractBox
Gets the box's content size. This excludes all header fields:

Flags and version of a full box need to be taken into account.

Specified by:
getContentSize in class AbstractBox
Returns:
Gets the box's content size in bytes

_parseDetails

public void _parseDetails(ByteBuffer content)
Description copied from class: AbstractBox
Implement the actual parsing of the box's fields here. External classes will always call AbstractBox.parseDetails() which encapsulates the call to this method with some safeguards.

Specified by:
_parseDetails in class AbstractBox

getContent

protected void getContent(ByteBuffer bb)
                   throws IOException
Description copied from class: AbstractBox
Writes the box's content into the given ByteBuffer. This must include flags and version in case of a full box. bb has been initialized with getSize() bytes.

Specified by:
getContent in class AbstractBox
Parameters:
bb - the box's content-sink.
Throws:
IOException - in case of an exception in the underlying OutputStream.
