<p>This function decodes a header packet from a Vorbis stream and applies
|
||
|
|
the contents to the given <a href="vorbis_info.html">vorbis_info</a>
|
||
|
|
structure (to provide codec parameters to the decoder) and
|
||
|
|
<a href="vorbis_comment.html">vorbis_comment</a> structure (to provide
|
||
|
|
access to the embedded Vorbis comments).</p>
|
||
|
|
|
||
|
|
<p>Once the three Vorbis header packets (info, comments,
|
||
|
|
and codebooks, in that order) have been passed to this
|
||
|
|
function, the <a href="vorbis_info.html">vorbis_info</a>
|
||
|
|
structure is ready to be used in a call to
|
||
|
|
<a href="vorbis_synthesis_init.html">vorbis_synthesis_init</a>.</p>
