All Implemented Interfaces:

Box

public class MetaBoxRelationBox
extends FullBox

The metabox relation box indicates a relation between two meta boxes at the same level, i.e., the top level of the file, the Movie Box, or Track Box. The relation between two meta boxes is unspecified if there is no metabox relation box for those meta boxes. Meta boxes are referenced by specifying their handler types.

Method Detail

decode

public void decode(MP4InputStream in)
            throws java.io.IOException

Description copied from class: BoxImpl

Decodes the given input stream by reading this box and all of its children (if any).

Overrides:

decode in class FullBox

Parameters:

in - an input stream

Throws:

java.io.IOException - if an error occurs while reading

getFirstMetaboxHandlerType

public long getFirstMetaboxHandlerType()

The first meta box to be related.

getSecondMetaboxHandlerType

public long getSecondMetaboxHandlerType()

The second meta box to be related.

getMetaboxRelation

public int getMetaboxRelation()

The metabox relation indicates the relation between the two meta boxes. The following values are defined:

1. The relationship between the boxes is unknown (which is the default when this box is not present)
2. the two boxes are semantically un-related (e.g., one is presentation, the other annotation)
3. the two boxes are semantically related but complementary (e.g., two disjoint sets of meta-data expressed in two different meta-data systems)
4. the two boxes are semantically related but overlap (e.g., two sets of meta-data neither of which is a subset of the other); neither is 'preferred' to the other
5. the two boxes are semantically related but the second is a proper subset or weaker version of the first; the first is preferred
6. the two boxes are semantically related and equivalent (e.g., two essentially identical sets of meta-data expressed in two different meta-data systems)
