<h1>Encoding</h1>
|
|
<p>Libogg contains a set of functions used in the encoding process.
|
|
<p>
|
|
All the <b>libogg</b> specific functions are declared in "ogg/ogg.h".
|
|
<p>
|
|
<p>When encoding, the encoding engine will output raw packets which must be placed into an Ogg bitstream.
|
|
<p>Raw packets are inserted into the stream, and an <a href="ogg_page.html">ogg_page</a> is output when enough packets have been written to create a full page. The pages output are pointers to buffered packet segments, and can then be written out and saved as an ogg stream.
|
|
<p>There are a couple of basic steps:
|
|
<ul>
|
|
<li>Use the encoding engine to produce a raw packet of data.
|
|
<li>Call <a href="ogg_stream_packetin.html">ogg_stream_packetin</a> to submit a raw packet to the stream.
|
|
<li>Use <a href="ogg_stream_pageout.html">ogg_stream_pageout</a> to output a page, if enough data has been submitted. Otherwise, continue submitting data.
|
|
</ul>
