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

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

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