Chris@1 18 <p><i>declared in "ogg/ogg.h";</i></p>
Chris@1 19
Chris@1 20 <p>This function forms packets into pages.</p>
Chris@1 21
Chris@1 22 <p>In a typical encoding situation, this would be called after using <a
Chris@1 23 href="ogg_stream_packetin.html">ogg_stream_packetin()</a> to submit
Chris@1 24 data packets to the bitstream. Internally, this function assembles
Chris@1 25 the accumulated packet bodies into an Ogg page suitable for writing
Chris@1 26 to a stream. The function is typically called in a loop until there
Chris@1 27 are no more pages ready for output.</p>
Chris@1 28
Chris@1 29 <p>This function will only return a page when a "reasonable" amount of
Chris@1 30 packet data is available. Normally this is appropriate since it
Chris@1 31 limits the overhead of the Ogg page headers in the bitstream, and so
Chris@1 32 calling ogg_stream_pageout() after ogg_stream_packetin() should be the
Chris@1 33 common case. Call <a href="ogg_stream_flush.html">ogg_stream_flush()</a>
Chris@1 34 if immediate page generation is desired. This may be occasionally
Chris@1 35 necessary, for example, to limit the temporal latency of a variable
Chris@1 36 bitrate stream.</p>

Chris@1 50 <dl>
Chris@1 51 <dt><i>os</i></dt>
Chris@1 52 <dd>Pointer to a previously declared <a href="ogg_stream.html">ogg_stream</a> struct, which represents the current logical bitstream.</dd>
Chris@1 53 <dt><i>og</i></dt>
Chris@1 54 <dd>Pointer to an <a href="ogg_page.html">ogg_page</a> structure to fill
Chris@1 55 in. Data pointed to is owned by libogg. The structure is valid until the
Chris@1 56 next call to ogg_stream_pageout(), ogg_stream_packetin(), or
Chris@1 57 ogg_stream_flush().</dd>
Chris@1 58 </dl>

Chris@1 60
Chris@1 61 <h3>Return Values</h3>
Chris@1 62 <blockquote>
Chris@1 63 <li>Zero means that insufficient data has accumulated to fill a page, or an internal error occurred. In
Chris@1 64 this case <i>og</i> is not modified.</li>
Chris@1 65 <li>Non-zero means that a page has been completed and returned.</li>
