 112 To use <a class="link" href="gst-plugins-good-plugins-gstrtpbin.html#GstRtpBin"><span class="type">GstRtpBin</span></a> as an RTP receiver, request a recv_rtp_sink_%d pad. The session
 113 number must be specified in the pad name.
 114 Data received on the recv_rtp_sink_%d pad will be processed in the <a class="link" href="gst-plugins-good-plugins-gstrtpsession.html#GstRtpSession"><span class="type">GstRtpSession</span></a>

 121 name.

 125 session number must be specified in the pad name.
 126 </p>
 127 <p>
 128 If you want the session manager to generate and send RTCP packets, request

 134 To use <a class="link" href="gst-plugins-good-plugins-gstrtpbin.html#GstRtpBin"><span class="type">GstRtpBin</span></a> as a sender, request a send_rtp_sink_%d pad, which will
 135 automatically create a send_rtp_src_%d pad. If the session number is not provided,
 136 the pad from the lowest available session will be returned. The session manager will modify the
 137 SSRC in the RTP packets to its own SSRC and wil forward the packets on the
 138 send_rtp_src_%d pad after updating its internal state.

 141 The session manager needs the clock-rate of the payload types it is handling

 147 Access to the internal statistics of gstrtpbin is provided with the
