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 SampleEntry

Parameters:

in - an input stream

Throws:

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

getPartitionEntryID

public int getPartitionEntryID()

The partition entry ID indicates the partition entry in the FD item information box. A zero value indicates that no partition entry is associated with this sample entry, e.g., for FDT. If the corresponding FD hint track contains only overhead data this value should indicate the partition entry whose overhead data is in question.

Returns:

the partition entry ID

getFECOverhead

public double getFECOverhead()

The FEC overhead is a floating point value indicating the percentage protection overhead used by the hint sample(s). The intention of providing this value is to provide characteristics to help a server select a session group (and corresponding FD hint tracks). If the corresponding FD hint track contains only overhead data this value should indicate the protection overhead achieved by using all FD hint tracks in a session group up to the FD hint track in question.

Returns:

the FEC overhead
