Class DataReferenceBox

  • All Implemented Interfaces:
    Box, Container, FullBox, ParsableBox
    public class DataReferenceBox
extends AbstractContainerBox
implements FullBox

    4cc = ""dref""

    The data reference object contains a table of data references (normally URLs) that declare the location(s) of the media data used within the presentation. The data reference index in the sample description ties entries in this table to the samples in the track. A track may be split over several sources in this way. If the flag is set indicating that the data is in the same file as this box, then no string (not even an empty one) shall be supplied in the entry field. The DataEntryBox within the DataReferenceBox shall be either a DataEntryUrnBox or a DataEntryUrlBox.

      • parse

        public void parse​(ReadableByteChannel dataSource,
                  ByteBuffer header,
                  long contentSize,
                  BoxParser boxParser)
           throws IOException
        Description copied from interface: ParsableBox
        Parses the box excluding the already parsed header (size, 4cc, [long-size], [user-type]). The remaining size of the box is the contentSize, contentSize number of bytes should be read from the box source (readableByteChannel). If you need the header buffer at a later stage you have to create a copy.
        Specified by:
        parse in interface ParsableBox
        Overrides:
        parse in class AbstractContainerBox
        Parameters:
        dataSource - the source for this box
        header - the box' already parsed header (create copy if you need it later as it will be overwritten)
        contentSize - remaining bytes of this box
        boxParser - use it to parse sub-boxes.
        Throws:
        IOException - in case of an error during a read operation

        public void getBox​(WritableByteChannel writableByteChannel)
            throws IOException
        Description copied from interface: Box
        Writes the complete box - size | 4-cc | content - to the given writableByteChannel.
        Specified by:

        Overrides:
        getBox in class AbstractContainerBox
        Parameters:
