<p>
GstIndex is used to generate a stream index of one or more elements
in a pipeline.
</p>
<p>
Elements will overload the set_index and get_index virtual methods in
<a class="link" href="GstElement.html" title="GstElement"><span class="type">GstElement</span></a>. When streaming data, the element will add index entries if it
has an index set.
</p>
<p>
Each element that adds to the index will do that using a writer_id. The
writer_id is obtained from <a class="link" href="GstIndex.html#gst-index-get-writer-id" title="gst_index_get_writer_id ()"><code class="function">gst_index_get_writer_id()</code></a>.
</p>
<p>
The application that wants to index the stream will create a new index object
using <a class="link" href="GstIndex.html#gst-index-new" title="gst_index_new ()"><code class="function">gst_index_new()</code></a> or <a class="link" href="GstIndexFactory.html#gst-index-factory-make" title="gst_index_factory_make ()"><code class="function">gst_index_factory_make()</code></a>. The index is assigned to a
specific element, a bin or the whole pipeline. This will cause indexable
elements to add entires to the index while playing.
