- * SECTION:element-dccpserversink
- * @see_also: dccpclientsink, dccpclientsrc, dccpserversrc
- *
- * This element wait for connections from clients and send data to them.
- * <ulink url="http://www.linuxfoundation.org/en/Net:DCCP">DCCP</ulink> (Datagram
- * Congestion Control Protocol) is a Transport Layer protocol like
- * TCP and UDP.
- *
- * <refsect2>
- * <title>Example pipeline</title>
- * <para>
- * |[
- * gst-launch -v dccpclientsrc host=localhost port=9011 ccid=2 ! decodebin ! alsasink
- * ]| Client
- * |[
- * gst-launch -v filesrc location=music.mp3 ! mp3parse ! dccpserversink port=9011 ccid=2
- * ]| Server
- *
- * This example pipeline will send a MP3 stream to the client using DCCP.
- * The client will decode the MP3 and play it. Run the server pipeline
- * first than the client pipeline. If you want, you can run more than one dccpclientsrc
- * to connect to the same server (see wait-connections property at dccpserversink).
