| The ogg_page struct encapsulates the data for an Ogg page. |
| <p> |
| Ogg pages are the fundamental unit of framing and interleave in an ogg bitstream. |
| They are made up of packet segments of 255 bytes each. There can be as many as |
| 255 packet segments per page, for a maximum page size of a little under 64 kB. |
| This is not a practical limitation as the segments can be joined across |
| page boundaries allowing packets of arbitrary size. In practice pages are |
| usually around 4 kB. |
| <p> |
| <p>For a complete description of ogg pages and headers, please refer to the <a href="../framing.html">framing document</a>. |
