<h1>ov_pcm_seek_page</h1>
|
|
|
|
<p><i>declared in "ivorbisfile.h";</i></p>
|
|
|
|
<p>Seeks to the closest page preceding the specified location (in pcm samples) within the physical bitstream. This function only works for seekable streams.
|
|
<p>This function is faster than <a href="ov_pcm_seek.html">ov_pcm_seek</a> because the function can begin decoding at a page boundary rather than seeking through any remaining samples before the specified location. However, it is less accurate.
|
|
<p>This also updates everything needed within the
|
|
decoder, so you can immediately call <a href="ov_read.html">ov_read()</a> and get data from
|
|
the newly seeked to position.
