+ * #GstRtpBin also has signals (#GstRtpBin::request-rtp-encoder,
+ * #GstRtpBin::request-rtp-decoder, #GstRtpBin::request-rtcp-encoder and
+ * #GstRtpBin::request-rtp-decoder) to dynamically request for RTP and RTCP encoders
+ * and decoders in order to support SRTP. The encoders must provide the pads
+ * rtp_sink_\%d and rtp_src_\%d for RTP and rtcp_sink_\%d and rtcp_src_\%d for
+ * RTCP. The session number will be used in the pad name. The decoders must provide
+ * rtp_sink and rtp_src for RTP and rtcp_sink and rtcp_src for RTCP. The decoders will
+ * be placed before the #GstRtpSession element, thus they must support SSRC demuxing
