<p>Read data from a unix file descriptor.</p>
<p>To generate data, enter some data on the console followed by enter.
The above mentioned pipeline should dump data packets to the console.</p>
<p>If the <a class="link" href="gstreamer-plugins-fdsrc.html#GstFdSrc--timeout" title="The “timeout” property"><span class="type">“timeout”</span></a> property is set to a value bigger than 0, fdsrc will
generate an element message named <code class="classname">"GstFdSrcTimeout"</code>
if no data was received in the given timeout.</p>
<p>The message's structure contains one field:</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
<span class="type">guint64</span>
<code class="classname">"timeout"</code>: the timeout in microseconds that
expired when waiting for data.
