|---|
| 20 | <p>For seekable |
|---|
| 21 | streams, this seeks to closest full page preceding the given time. This function is faster than <a href="ov_time_seek.html">ov_time_seek</a> because it doesn't seek through the last few samples to reach an exact time, but it is also less accurate. This should be used when speed is important. |
|---|
| 22 | <p>This function also updates everything needed within the |
|---|
| 23 | decoder, so you can immediately call <a href="ov_read.html">ov_read()</a> and get data from |
|---|
| 24 | the newly seeked to position. |
|---|
| 25 | <p>This function does not work for unseekable streams. |
