The different tag merging modes are basically replace, overwrite and append,
but they can be seen from two directions. Given two taglists: (A) the tags
already in the element and (B) the ones that are supplied to the element (
e.g. via <a class="link" href="GstTagSetter.html#gst-tag-setter-merge-tags" title="gst_tag_setter_merge_tags ()"><code class="function">gst_tag_setter_merge_tags()</code></a> / <a class="link" href="GstTagSetter.html#gst-tag-setter-add-tags" title="gst_tag_setter_add_tags ()"><code class="function">gst_tag_setter_add_tags()</code></a> or a
<a class="link" href="gstreamer-GstEvent.html#GST-EVENT-TAG:CAPS"><code class="literal">GST_EVENT_TAG</code></a>), how are these tags merged?
In the table below this is shown for the cases that a tag exists in the list
(A) or does not exists (!A) and combinations thereof.

<p>
Registers a new tag type for the use with GStreamer's type system. If a type
with that name is already registered, that one is used.
The old registration may have used a different type however. So don't rely
on your supplied values.
</p>
<p>
Important: if you do not supply a merge function the implication will be
that there can only be one single value for this tag in a tag list and
any additional values will silenty be discarded when being added (unless
<a class="link" href="gstreamer-GstTagList.html#GST-TAG-MERGE-REPLACE:CAPS"><span class="type">GST_TAG_MERGE_REPLACE</span></a>, <a class="link" href="gstreamer-GstTagList.html#GST-TAG-MERGE-REPLACE-ALL:CAPS"><span class="type">GST_TAG_MERGE_REPLACE_ALL</span></a>, or
<a class="link" href="gstreamer-GstTagList.html#GST-TAG-MERGE-PREPEND:CAPS"><span class="type">GST_TAG_MERGE_PREPEND</span></a> is used as merge mode, in which case the new
value will replace the old one in the list).
</p>
<p>
The merge function will be called from <a class="link" href="gstreamer-GstTagList.html#gst-tag-list-copy-value" title="gst_tag_list_copy_value ()"><code class="function">gst_tag_list_copy_value()</code></a> when

exactly in that case depends on how the tag was registered and if a
