|
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 many
|
|
applications will not completely fill all pages because they flush the
|
|
accumulated packets periodically order to bound latency more tightly.
|
|

|
|
