Constructors Summary
public Mp4TagBinaryField(String id) Construct an empty Binary Field param id super(id);
public Mp4TagBinaryField(String id, byte[] data) Construct new binary field with binarydata provided param id param data throws UnsupportedEncodingException super(id); this.dataBytes = data;
public Mp4TagBinaryField(String id, ByteBuffer raw) Construct binary field from rawdata of audio file param id param raw throws UnsupportedEncodingException super(id, raw);

Methods Summary
