/**
* SECTION:element-udpsrc
* @see_also: udpsink, multifdsink
*
* <refsect2>
* <para>
* udpsrc is a network source that reads UDP packets from the network.
* It can be combined with RTP depayloaders to implement RTP streaming.
* </para>
* <title>Examples</title>
* <para>
* Here is a simple pipeline to read from the default port and dump the udp packets.
* <programlisting>
* gst-launch -v udpsrc ! fakesink dump=1
* </programlisting>
* To actually generate udp packets on the default port one can use the
* udpsink element. When running the following pipeline in another terminal, the
* above mentioned pipeline should dump data packets to the console.
* <programlisting>
* gst-launch -v audiotestsrc ! udpsink
* </programlisting>
* </para>
* <para>
* The udpsrc element supports automatic port allocation by setting the
* "port" property to 0. the following pipeline reads UDP from a free port.
* <programlisting>
* gst-launch -v udpsrc port=0 ! fakesink
* </programlisting>
* </para>
* <para>
* udpsrc can read from multicast groups by setting the multicast_group property
* to the IP address of the multicast group.
* </para>
* <para>
* Alternatively one can provide a custom socket to udpsrc with the "sockfd" property,
* udpsrc will then not allocate a socket itself but use the provided one.
* </para>
* <para>
* The "caps" property is mainly used to give a type to the UDP packet so that they
* can be autoplugged in GStreamer pipelines. This is very usefull for RTP
* implementations where the contents of the UDP packets is transfered out-of-bounds
* using SDP or other means.
* </para>
* <para>
* The udpsrc is always a live source. It does however not provide a GstClock, this
* is left for upstream elements such as an RTP session manager or demuxer (such
* as an MPEG demuxer).
* </para>
* <para>
* udpsrc implements a GstURIHandler interface that handles udp://host:port type
* URIs.
* </para>
* </refsect2>
