 114 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
 115 number must be specified in the pad name.
 116 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 on the payload type and will create a unique pad recv_rtp_src_%d_%d_%d on
 122 gstrtpbin with the session number, SSRC and payload type respectively as the pad
 123 name.

 127 session number must be specified in the pad name.
 128 </p>
 129 <p>
 130 If you want the session manager to generate and send RTCP packets, request
 131 the send_rtcp_src_%d pad with the session number in the pad name. Packet pushed

 136 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
 137 automatically create a send_rtp_src_%d pad. If the session number is not provided,
 138 the pad from the lowest available session will be returned. The session manager will modify the
 139 SSRC in the RTP packets to its own SSRC and wil forward the packets on the
 140 send_rtp_src_%d pad after updating its internal state.

 142 <p>
 143 The session manager needs the clock-rate of the payload types it is handling

 149 Access to the internal statistics of gstrtpbin is provided with the
 150 get-internal-session property. This action signal gives access to the
