<p>
The valve is a simple element that drops buffers when the <span class="type">"drop"</span>
property is set to <a
href="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#TRUE--CAPS"
><code class="literal">TRUE</code></a> and lets then through otherwise.
</p>
<p>
Any downstream error received while the <span class="type">"drop"</span> property is <a
href="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#FALSE--CAPS"
><code class="literal">FALSE</code></a>
is ignored. So downstream element can be set to <code class="literal">GST_STATE_NULL</code> and removed,
without using pad blocking.
