<h1>Seeking</h1>
|
|
<p>Seeking functions allow you to specify a specific point in the stream to begin or continue decoding.
|
|
<p>
|
|
All libvorbisidec seeking routines are declared in "ivorbisfile.h".
|
|
|
|
<p>Certain seeking functions are best suited to different situations.
|
|
When speed is important and exact positioning isn't required,
|
|
page-level seeking should be used. Note also that Vorbis files do not
|
|
necessarily start at a sample number or time offset of zero. Do not
|
|
be surprised if a file begins at a positive offset of several minutes
|
|
or hours, such as would happen if a large stream (such as a concert
|
|
recording) is chopped into multiple separate files. Requesting to
|
|
seek to a position before the beginning of such a file will seek to
|
|
the position where audio begins.<p>
