| <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> |
