/**
* SECTION:element-valve
+ * @title: valve
*
* The valve is a simple element that drops buffers when the #GstValve:drop
* property is set to %TRUE and lets then through otherwise.
*
- * Any downstream error received while the #GstValve:drop property is %FALSE
+ * Any downstream error received while the #GstValve:drop property is %TRUE
* is ignored. So downstream element can be set to %GST_STATE_NULL and removed,
* without using pad blocking.
- *
- * This element was previously part of gst-plugins-farsight, and then
- * gst-plugins-bad.

- * Documentation last reviewed on 2010-12-30 (0.10.31)
