Tremor is extremly similar to libogg but only uses integers (and doesn't provide an encoder). The playing problem with libvorbis was probably a float-precision related issue. No need for make build-all.

<h1>ov_bitrate</h1>
|
|
|
|
<p><i>declared in "ivorbisfile.h";</i></p>
|
|
|
|
<p>This function returns the average bitrate for the specified logical bitstream. This may be different from the <a href=ov_info.html>ov_info->nominal_bitrate</a> value, as it is based on the actual average for this bitstream if the file is seekable.
|
|
<p>Nonseekable files will return the nominal bitrate setting or the average of the upper and lower bounds, if any of these values are set.

<h3>Parameters</h3>
|
|
<dl>
|
|
<dt><i>vf</i></dt>
|
|
<dd>A pointer to the OggVorbis_File structure--this is used for ALL the externally visible libvorbisidec
|
|
functions.</dd>
|
|
<dt><i>i</i></dt>
|
|
<dd>Link to the desired logical bitstream. For nonseekable files, this argument is ignored. To retrieve the bitrate for the entire bitstream, this parameter should be set to -1.</dd>
|
|
</dl>
|
|
|
|
|
|
<h3>Return Values</h3>
|
|
<blockquote>
|
|
<li>OV_EINVAL indicates that an invalid argument value was submitted or that the stream represented by <tt>vf</tt> is not open.</li>
|
|
<li>OV_FALSE means the call returned a 'false' status, which in this case most likely indicates that the file is nonseekable and the upper, lower, and nominal bitrates were unset.
|
|
<li><i>n</i> indicates the bitrate for the given logical bitstream or the entire
|
|
physical bitstream. If the file is open for random (seekable) access, it will
|
|
find the *actual* average bitrate. If the file is streaming (nonseekable), it
|
|
returns the nominal bitrate (if set) or else the average of the
|
|
upper/lower bounds (if set).</li>
