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’.

    • 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

      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
