-<h1>Decoding</h1>
-<p>Libogg contains a set of functions used in the decoding process.
-<p>
-All the <b>libogg</b> specific functions are declared in "ogg/ogg.h".
-<p>
-<p>Decoding is based around the ogg synchronization layer. The <a href="ogg_sync_state.html">ogg_sync_state</a> struct coordinates between incoming data and the decoder. We read data into the synchronization layer, submit the data to the stream, and output raw packets to the decoder.
-<p>Decoding through the Ogg layer follows a specific logical sequence. A read loop follows these logical steps:
-<ul>
-<li>Expose a buffer using <a href="ogg_sync_buffer.html">ogg_sync_buffer()</a>.
-<li>Read data into the buffer, using fread() or a similar function.
-<li>Call <a href="ogg_sync_wrote.html">ogg_sync_wrote()</a> to tell the synchronization layer how many bytes you wrote into the buffer.
-<li>Write out the data using <a href="ogg_sync_pageout.html">ogg_sync_pageout</a>.
-<li>Submit the completed page to the streaming layer with <a href="ogg_stream_pagein.html">ogg_stream_pagein</a>.
-<li>Output a packet of data to the codec-specific decoding layer using <a href="ogg_stream_packetout.html">ogg_stream_packetout</a>.
-</ul>
-<p>In practice, streams are more complex, and Ogg also must handle headers, incomplete or dropped pages, and other errors in input.
