In these cases, the size of the buffer can be recommended by the - * server using the <i>Recommended buffer size</i> frame. If the embedded info - * flag is set then this indicates that an ID3 tag with the maximum size - * described in buffer size may occur in the audio stream. In such case the tag - * should reside between two MPEG frames, if the audio is MPEG encoded. If the - * position of the next tag is known, offset to next tag may be used. The offset - * is calculated from the end of tag in which this frame resides to the first - * byte of the header in the next. This field may be omitted. Embedded tags are - * generally not recommended since this could render unpredictable behaviour - * from present software/hardware. - * - * For applications like streaming audio it might be an idea to embed tags into - * the audio stream though. If the clients connects to individual connections - * like HTTP and there is a possibility to begin every transmission with a tag, - * then this tag should include a recommended buffer size frame. If the client - * is connected to a arbitrary point in the stream, such as radio or multicast, - * then the recommended buffer size frame should be included in every tag. - * - * The buffer size should be kept to a minimum. There may only be one RBUF - * frame in each tag. - * - * @package php-reader - * @subpackage ID3 - * @author Sven Vollbehr <svollbehr@gmail.com> - * @author Ryan Butterfield <buttza@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: 105 $ - */ -final class ID3_Frame_RBUF extends ID3_Frame -{ - /** - * A flag to denote that an ID3 tag with the maximum size described in buffer - * size may occur in the audio stream. - */ - const EMBEDDED = 0x1; - - /** @var integer */ - private $_bufferSize; - - /** @var integer */ - private $_infoFlags; - - /** @var integer */ - private $_offset = 0; - - /** - * Constructs the class with given parameters and parses object related data. - * - * @param Reader $reader The reader object. - * @param Array $options The options array. - */ - public function __construct($reader = null, &$options = array()) - { - parent::__construct($reader, $options); - - if ($reader === null) - return; - - $this->_bufferSize = - Transform::fromUInt32BE("\0" . substr($this->_data, 0, 3)); - $this->_infoFlags = Transform::fromInt8($this->_data[3]); - if ($this->getSize() > 4) - $this->_offset = Transform::fromInt32BE(substr($this->_data, 4, 4)); - } - - /** - * Returns the buffer size. - * - * @return integer - */ - public function getBufferSize() { return $this->_bufferSize; } - - /** - * Sets the buffer size. - * - * @param integer $size The buffer size. - */ - public function setBufferSize($bufferSize) - { - $this->_bufferSize = $bufferSize; - } - - /** - * Checks whether or not the flag is set.
