<h1>vorbis_synthesis_lapout</h1>
|
|
|
|
<p><i>declared in "vorbis/codec.h";</i></p>
|
|
|
|
<p>This function retrieves buffers containing decoded audio samples, similarly
|
|
to <a href="vorbis_synthesis_pcmout.html">vorbis_synthesis_pcmout</a>.
|
|
However, it includes some extra samples extrapolated from the end of
|
|
the audio, suitable for crosslapping with other blocks. This exists mainly
|
|
for <a href="../vorbisfile/index.html">libvorbisfile</a> to use for
|
|
handling chained bitstreams and bitstreams with holes.</p>

<h3>Parameters</h3>
|
|
<dl>
|
|
<dt><i>v</i></dt>
|
|
<dd>The <a href="vorbis_dsp_state.html">vorbis_dsp_state</a> for the
|
|
decoder instance.</dd>
|
|
<dt><i>pcm</i></dt>
|
|
<dd>A pointer to a float** which will be made to point to an array of
|
|
pointers to the decoded samples for each channel. The memory is owned
|
|
by the decoder instance and will be freed when the application continues
|
|
decoding or destroys the decoder instance. This can be NULL, in which
|
|
case the return value gives the number of samples that would be returned
|
|
if this function were called with a non-NULL pointer here.</dd>
|
|
</dl>
|

|
|
|
|
<h3>Return Values</h3>
|
|
<blockquote>
|
|
<li>The number of samples available in the output buffer.</li>
|
|
<li>0 if no more samples are currently available.</li>
