Class DataReferenceBox

java.lang.Object

com.googlecode.mp4parser.BasicContainer

com.googlecode.mp4parser.AbstractContainerBox

com.coremedia.iso.boxes.DataReferenceBox

All Implemented Interfaces:

Box, Container, FullBox, Closeable, AutoCloseable, Iterator<Box>

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(DataSource dataSource,
         ByteBuffer header,
         long contentSize,
         BoxParser boxParser)
           throws IOException

Description copied from interface: Box

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 Box

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

getBox

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:

getBox in interface Box

Overrides:

getBox in class AbstractContainerBox

Parameters:

writableByteChannel - the box's sink

Throws:

IOException - in case of problems with the Channel

getSize

public long getSize()

Specified by:

getSize in interface Box

Overrides:

getSize in class AbstractContainerBox
