Placing this in binary format enables common handling - * of this data, even by systems which do not understand the particular metadata - * system (handler) used. For example, a system might integrate all the - * externally referenced metadata resources into one file, re-adjusting file - * offsets and file references accordingly. - * - * Items may be stored fragmented into extents, e.g. to enable interleaving. An - * extent is a contiguous subset of the bytes of the resource; the resource is - * formed by concatenating the extents. If only one extent is used then either - * or both of the offset and length may be implied: - * - * o If the offset is not identified (the field has a length of zero), then - * the beginning of the file (offset 0) is implied. - * o If the length is not specified, or specified as zero, then the entire - * file length is implied. References into the same file as this metadata, - * or items divided into more than one extent, should have an explicit - * offset and length, or use a MIME type requiring a different - * interpretation of the file, to avoid infinite recursion. - * - * The size of the item is the sum of the extentLengths. Note: extents may be - * interleaved with the chunks defined by the sample tables of tracks. - * - * The dataReferenceIndex may take the value 0, indicating a reference into the - * same file as this metadata, or an index into the dataReference table. - * - * Some referenced data may itself use offset/length techniques to address - * resources within it (e.g. an MP4 file might be included in this way). - * Normally such offsets are relative to the beginning of the containing file. - * The field base offset provides an additional offset for offset calculations - * within that contained data. For example, if an MP4 file is included within a - * file formatted to this specification, then normally data-offsets within that - * MP4 section are relative to the beginning of file; baseOffset adds to those - * offsets. - * - * @package php-reader - * @subpackage ISO 14496 - * @author Sven Vollbehr - * @copyright Copyright (c) 2008 The PHP Reader Project Workgroup - * @license http://code.google.com/p/php-reader/wiki/License New BSD License - * @version $Rev: 92 $ - */ -final class ISO14496_Box_ILOC extends ISO14496_Box -{ - /** @var Array */ - private $_items = array(); - - /** - * Constructs the class with given parameters and reads box related data from - * the ISO Base Media file. - * - * @param Reader $reader The reader object. - */ - public function __construct($reader, &$options = array()) - { - parent::__construct($reader, $options); - - $offsetSize = (($tmp = $this->_reader->readUInt32BE()) >> 28) & 0xf; - $lengthSize = ($tmp >> 24) & 0xf; - $baseOffsetSize = ($tmp >> 20) & 0xf; - $itemCount = $this->_reader->readUInt16BE(); - for ($i = 0; $i < $itemCount; $i++) { - $item = array(); - $item["itemId"] = $this->_reader->readUInt16BE(); - $item["dataReferenceIndex"] = $this->_reader->readUInt16BE(); - $item["baseOffset"] = - ($baseOffsetSize == 4 ? $this->_reader->readUInt32BE() : - ($baseOffsetSize == 8 ? $this->_reader->readInt64BE() : 0)); - $item["extents"] = array(); - for ($j = 0; $j < $extentCount; $j++) { - $extent = array(); - $extent["offset"] = - ($offsetSize == 4 ? $this->_reader->readUInt32BE() : - ($offsetSize == 8 ? $this->_reader->readInt64BE() : 0)); - $extent["length"] = - ($lengthSize == 4 ? $this->_reader->readUInt32BE() : - ($lengthSize == 8 ? $this->_reader->readInt64BE() : 0)); - $item["extents"][] = $extent; - } - $this->_items[] = $item; - } - } - - /** - * Returns the array of items.
