<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
