20 <p>For seekable
|
|
cannam@86
|
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.
|
|
cannam@86
|
22 <p>This function also updates everything needed within the
|
|
cannam@86
|
23 decoder, so you can immediately call <a href="ov_read.html">ov_read()</a> and get data from
|
|
cannam@86
|
24 the newly seeked to position.
|
|
cannam@86
|
25 <p>This function does not work for unseekable streams.
