It + * contains a track fragment random access box for each track for which + * information is provided (which may not be all tracks). It is usually placed + * at or near the end of the file; the last box within the Movie Fragment Random + * Access Box provides a copy of the length field from the Movie Fragment Random + * Access Box. Readers may attempt to find this box by examining the last 32 + * bits of the file, or scanning backwards from the end of the file for a Movie + * Fragment Random Access Offset Box and using the size information in it, to + * see if that locates the beginning of a Movie Fragment Random Access Box. + * + * This box provides only a hint as to where random access points are; the movie + * fragments themselves are definitive. It is recommended that readers take care + * in both locating and using this box as modifications to the file after it was + * created may render either the pointers, or the declaration of random access + * points, incorrect. + * + * @package php-reader + * @subpackage ISO 14496 + * @author Sven Vollbehr <svollbehr@gmail.com> + * @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_MFRA extends ISO14496_Box +{ + /** + * 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 = null, &$options = array()) + { + parent::__construct($reader, $options); + $this->setContainer(true); + + if ($reader === null) + return; + + $this->constructBoxes(); + } +} |
