If producer’s stats is an empty array it means that no RTP stream has been created, so you should check whether the info in the producer `rtpParameters` matches the content of the RTP packets that gstreamer is sending to mediasoup (ssrc, payload type, etc). For example, **why** are you indicating `encodings : [{ ssrc: 21233452222 }]`? ---

You are right. ı replaced gstreamer code ```auto g_object_set (G_OBJECT (rtpvp8pay), "pt",101, NULL); g_object_set (G_OBJECT (rtpvp8pay), "ssrc",21233452222, NULL); ``` this.VideoProducer stats =\> > [{“bitrate”:618397,“byteCount”:20342242,“firCount”:0,“fractionLost”:0,“jitter”:0,“kind”:“video”,“mimeType”:“video/VP8”,“nackCount”:0,“nackPacketCount”:0,“packetCount”:15687,“packetsDiscarded”:0,“packetsLost”:0,“packetsRepaired”:0,“packetsRetransmitted”:0,“pliCount”:0,“score”:10,“ssrc”:4053583038,“timestamp”:1234457,“type”:“inbound-rtp”}] ```auto [ { "bitrate": 0, "byteCount": 0, "firCount": 0, "fractionLost": 0, "kind": "video", "mimeType": "video/VP8", "nackCount": 0, "nackPacketCount": 0, "packetCount": 0, "packetsDiscarded": 0, "packetsLost": 0, "packetsRepaired": 0, "packetsRetransmitted": 0, "pliCount": 1, "rtxSsrc": 601196453, "score": 10, "ssrc": 138528736, "timestamp": 1148445, "type": "outbound-rtp" }, { "bitrate": 906630, "byteCount": 12752429, "firCount": 0, "fractionLost": 0, "jitter": 0, "kind": "video", "mimeType": "video/VP8", "nackCount": 0, "nackPacketCount": 0, "packetCount": 9762, "packetsDiscarded": 0, "packetsLost": 0, "packetsRepaired": 0, "packetsRetransmitted": 0, "pliCount": 0, "score": 10, "ssrc": 4053583038, "timestamp": 1148445, "type": "inbound-rtp" } ] ``` consumer outbound-rtp byteCount is 0 but inbound-rtp bytecount is 12752429 why could it be ? ---

okey it worked added Code > g\_object\_set (G\_OBJECT (rtpvp8pay), “picture-id-mode”,2, NULL); changed code ```auto gst_element_link_pads(rtpvp8pay,"src", rtpbin,"send_rtp_sink_0 "); gst_element_link_pads(rtpbin,"send_rtp_src_0", udpSink,"sink"); gst_element_link_pads(rtpbin,"send_rtcp_src_0", udpSinkRtcp,"sink"); ``` to ```auto gst_element_link(rtpvp8pay, udpSink); ``` ı removed to rtcp port and ı sending mediasoup only rtp is this right ?
