<div class="textblock"><p>An interface that allows setting and retrieval of media metadata. </p>
<p>Elements that support changing a stream's metadata will implement this interface. Examples of such elements are 'vorbisenc', 'theoraenc' and 'id3v2mux'.</p>
<p>If you just want to retrieve metadata in your application then all you need to do is watch for tag messages on your pipeline's bus. This interface is only for setting metadata, not for extracting it. To set tags from the application, find tagsetter elements and set tags using e.g. <a class="el" href="classGst_1_1TagSetter.html#a252d57fb8831206eed177cdd7003cb6b" title="Merges the given list into the setter's list using the given mode. ">merge_tags()</a> or add_tags(). The application should do that before the element goes to <a class="el" href="namespaceGst.html#gabb043e1d41659fd842f10949f91e7a7fa702f01b465f78938c8d8467a6c6892d3" title="The element is PAUSED, it is ready to accept and process data. ">Gst::STATE_PAUSED</a>. </p>
