The vorbistags element can change the tag contained within a raw
vorbis stream. Specifically, it modifies the comments header packet
of the vorbis stream.
</p>
<p>
The element will also process the stream as the <span class="type">vorbisparse</span> element does
so it can be used when remuxing an Ogg Vorbis stream, without additional
elements.
</p>
<p>
Applications can set the tags to write using the <span class="type">GstTagSetter</span> interface.
Tags contained withing the vorbis bitstream will be picked up
automatically (and merged according to the merge mode set via the tag
setter interface).
</p>
<h3>Example pipelines</h3>
<p>
This element is not useful with gst-launch, because it does not support
setting the tags on a <span class="type">GstTagSetter</span> interface. Conceptually, the element
will usually be used like:
</p>
<pre class="programlisting">
gst-launch -v filesrc location=foo.ogg ! oggdemux ! vorbistag ! oggmux ! filesink location=bar.ogg
</pre>
<p>
