While we don't have the struct to represent RTCP APP packet, you could use the generic RTCP packet "template" (struct pjmedia_rtcp_common) to build any RTCP packets. See create_rtcp_sdes() and create_rtcp_bye() in stream.c for sample codes. For now I don't think we need to add explicit support RTCP APP and every other RTCP packets out there. Cheers Benny
