hello everyone `gst-launch-1.0 audiotestsrc ! audioresample ! audio/x-raw,channels=2,rate=48000 ! opusenc bitrate=20000 ! rtpopuspay pt=101 ssrc=1112223 ! udpsink host=127.0.0.1 port=20157` gstreamer sending rtp packet to mediasoup MediaSoup PlainTransport =\> ```auto this.AudioProducer = await this.AudioPlainTransPort.produce( { kind : 'audio', rtpParameters : { codecs : [ { mimeType : 'audio/opus', clockRate : 48000, payloadType : 101, channels : 2, rtcpFeedback : [], parameters : { 'sprop-stereo': 1 } } ], encodings : [{ ssrc: 1112223 }] }, paused: false }); ``` but AudioProducer stats is empty ```auto this.AudioProducer.getStats() .then(stats => console.warn("this.AudioProducer => "+JSON.stringify(stats))); ``` output this.AudioProducer =\> [] ---

There are tons of debugs and log tags in mediasoup to diagnose what is wrong with received RTP (if any). Use them. ---
