| 16 | <h1>Encoding</h1> |
|---|
| 17 | <p>Libogg contains a set of functions used in the encoding process. |
|---|
| 18 | <p> |
|---|
| 19 | All the <b>libogg</b> specific functions are declared in "ogg/ogg.h". |
|---|
| 20 | <p> |
|---|
| 21 | <p>When encoding, the encoding engine will output raw packets which must be placed into an Ogg bitstream. |
|---|
| 22 | <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. |
|---|
| 23 | <p>There are a couple of basic steps: |
|---|
| 24 | <ul> |
|---|
| 25 | <li>Use the encoding engine to produce a raw packet of data. |
|---|
| 26 | <li>Call <a href="ogg_stream_packetin.html">ogg_stream_packetin</a> to submit a raw packet to the stream. |
|---|
| 27 | <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. |
|---|
| 28 | </ul> |
