| 20 | <p>This function forms packets into pages, similar
|
|---|
| 21 | to <a href="ogg_stream_pageout.html">ogg_stream_pageout()</a>, but
|
|---|
| 22 | allows applications to explicitly request a specific page spill
|
|---|
| 23 | size.</p>
|
|---|
| 24 |
|
|---|
| 25 | <p>In a typical encoding situation, this would be called after using <a
|
|---|
| 26 | href="ogg_stream_packetin.html">ogg_stream_packetin()</a> to submit
|
|---|
| 27 | data packets to the bitstream. Internally, this function assembles
|
|---|
| 28 | the accumulated packet bodies into an Ogg page suitable for writing
|
|---|
| 29 | to a stream. The function is typically called in a loop until there
|
|---|
| 30 | are no more pages ready for output.</p>
|
|---|
| 31 |
|
|---|
| 32 | <p>This function will return a page when at least four packets have
|
|---|
| 33 | been accumulated and accumulated packet data meets or exceeds the
|
|---|
| 34 | specified number of bytes, <b>and/or</b> when the accumulated packet
|
|---|
| 35 | data meets/exceeds the maximum page size regardless of accumulated
|
|---|
| 36 | packet count.
|
|---|
| 37 | Call <a href="ogg_stream_flush.html">ogg_stream_flush()</a> or
|
|---|
| 38 | <a href="ogg_stream_flush_fill.html">ogg_stream_flush_fill()</a> if
|
|---|
| 39 | immediate page generation is desired regardless of accumulated data.</p>
