This variant of <a +href="ov_time_seek.html">ov_time_seek</a> also automatically +crosslaps the transition from the previous playback position into the +new playback position in order to eliminate clicking and boundary +discontinuities. Otherwise, usage and behavior is identical to <a +href="ov_time_seek.html">ov_time_seek</a>. + +<p>ov_time_seek_lap 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. + +<p>ov_time_seek_lap will lap between logical stream links of differing +numbers of channels. Any extra channels from the origin of the seek +are ignored; playback of these channels simply ends. Extra channels at +the destination are lapped from silence. ov_time_seek_lap will also +lap between logical stream links of differing sample rates. In this +case, the sample rates are ignored (no implicit resampling is done to +match playback). It is up to the application developer to decide if +this behavior makes any sense in a given context; in practical use, +these default behaviors perform sensibly. + +<p> This function does not work for unseekable streams. + + +<br><br> +<table border=0 color=black cellspacing=0 cellpadding=7> +<tr bgcolor=#cccccc> + <td> +<pre><b> +int ov_time_seek_lap(<a href="OggVorbis_File.html">OggVorbis_File</a> *vf, double s); +</b></pre> + </td> +</tr> +</table> + +<h3>Parameters</h3> +<dl> +<dt><i>vf</i></dt> +<dd>Pointer to our already opened and initialized OggVorbis_File structure.</dd> +<dt><i>pos</i></dt> +<dd>Location to seek to within the file, specified in seconds.</dd> +</dl> + + +<h3>Return Values</h3> +<blockquote> +<ul> +<li>0 for success</li> + +<li> +nonzero indicates failure, described by several error codes: + <ul> + <li>OV_ENOSEEK - Bitstream is not seekable. + </li> + <li>OV_EINVAL - Invalid argument value; possibly called with an OggVorbis_File structure that isn't open. + </li> + <li>OV_EREAD - A read from media returned an error. + </li> + <li>OV_EFAULT - Internal logic fault; indicates a bug or heap/stack + corruption. + </li> + <li>OV_EOF - Indicates stream is at end of file immediately after a seek + (making crosslap impossible as there's no preceeding decode state to crosslap). + </li> + <li>OV_EBADLINK - Invalid stream section supplied to libvorbisfile, or the requested link is corrupt. + </li> + </ul></li> +</ul></blockquote> + + +<br><br> +<hr noshade> +<table border=0 width=100%> +<tr valign=top> +<td><p class=tiny>copyright © 2000-2010 Xiph.Org</p></td> +<td align=right><p class=tiny><a href="http://www.xiph.org/ogg/vorbis/">Ogg Vorbis</a></p></td> +</tr><tr> +<td><p class=tiny>Vorbisfile documentation</p></td> +<td align=right><p class=tiny>vorbisfile version 1.3.2 - 20101101</p></td> +</tr> +</table> + +</body> + +</html> |
