It includes stream-specific indexing information - * based on an adjustable index entry media object count interval. This object - * can be used to index all the video frames or key frames in a video stream. - * The index is designed to be broken into blocks to facilitate storage that is - * more space-efficient by using 32-bit offsets relative to a 64-bit base. That - * is, each index block has a full 64-bit offset in the block header that is - * added to the 32-bit offset found in each index entry. If a file is larger - * than 2^32 bytes, then multiple index blocks can be used to fully index the - * entire large file while still keeping index entry offsets at 32 bits. - * - * Indices into the <i>Media Object Index Object</i> are in terms of media - * object numbers, with the first frame for a given stream in the ASF file - * corresponding to entry 0 in the <i>Media Object Index Object</i>. The - * corresponding <i>Offset</i> field values of the <i>Index Entry</i> are byte - * offsets that, when combined with the <i>Block Position</i> value of the - * Index Block, indicate the starting location in bytes of an ASF Data Packet - * relative to the start of the first ASF Data Packet in the file. - * - * Any ASF file containing a <i>Media Object Index Object</i> shall also contain - * a <i>Media Object Index Parameters Object</i> in its - * {@link ASF_Object_Header ASF Header}. - * - * @package php-reader - * @subpackage ASF - * @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: 108 $ - */ -final class ASF_Object_MediaObjectIndex extends ASF_Object -{ - /** - * Indicates that the index type is Nearest Past Data Packet.
