This problem can be solved by refreshing page several times.And I’ve checked the producer and consumer info. When it occurs case 1: producer icestate is “new” not “finished” nor “completed” case 2: consumer can not consume any data (sometimes no audio && video, no video but audio)

Optimization: // - Create the server-side Consumer in paused mode. // - Tell its Peer about it and wait for its response. // - Upon receipt of the response, resume the server-side Consumer. // - If video, this will mean a single key frame requested by the // server-side Consumer (when resuming it). // - If audio (or video), it will avoid that RTP packets are received by the // remote endpoint *before* the Consumer is locally created in the endpoint // (and before the local SDP O/A procedure ends). If that happens (RTP // packets are received before the SDP O/A is done) the PeerConnection may // fail to associate the RTP stream. // NOTE: Don't create the Consumer if the remote Peer cannot consume it. if ( !consumerPeer.data.rtpCapabilities || !this._mediasoupRouter.canConsume( { producerId : producer.id, rtpCapabilities : consumerPeer.data.rtpCapabilities }) ) { return; } // Must take the Transport the remote Peer is using for consuming. const transport = Array.from(consumerPeer.data.transports.values()) .find((t) => t.appData.consuming); // This should not happen. if (!transport) { logger.warn('_createConsumer() | Transport for consuming not found'); return; } // Create the Consumer in paused mode. let consumer; try { consumer = await transport.consume( { producerId : producer.id, rtpCapabilities : consumerPeer.data.rtpCapabilities, paused : true }); } catch (error) { logger.warn('_createConsumer() | transport.consume():%o', error); return; } // Store the Consumer into the protoo consumerPeer data Object. consumerPeer.data.consumers.set(consumer.id, consumer); // Set Consumer events. consumer.on('transportclose', () => { // Remove from its map. consumerPeer.data.consumers.delete(consumer.id); }); consumer.on('producerclose', () => { // Remove from its map. consumerPeer.data.consumers.delete(consumer.id); consumerPeer.notify('consumerClosed', { consumerId: consumer.id }) .catch(() => {}); }); consumer.on('producerpause', () => { consumerPeer.notify('consumerPaused', { consumerId: consumer.id }) .catch(() => {}); }); consumer.on('producerresume', () => { consumerPeer.notify('consumerResumed', { consumerId: consumer.id }) .catch(() => {}); }); consumer.on('score', (score) => { // logger.debug( // 'consumer "score" event [consumerId:%s, score:%o]', // consumer.id, score); consumerPeer.notify('consumerScore', { consumerId: consumer.id, score }) .catch(() => {}); }); consumer.on('layerschange', (layers) => { consumerPeer.notify( 'consumerLayersChanged', { consumerId : consumer.id, spatialLayer : layers ? layers.spatialLayer : null, temporalLayer : layers ? layers.temporalLayer : null }) .catch(() => {}); }); // NOTE: For testing. // await consumer.enableTraceEvent(['rtp', 'keyframe', 'nack', 'pli', 'fir']); // await consumer.enableTraceEvent(['pli', 'fir']); // await consumer.enableTraceEvent(['keyframe']); consumer.on('trace', (trace) => { logger.debug( 'consumer "trace" event [producerId:%s, trace.type:%s, trace:%o]', consumer.id, trace.type, trace); }); // Send a protoo request to the remote Peer with Consumer parameters. try { await consumerPeer.request( 'newConsumer', { peerId : producerPeer.id, producerId : producer.id, id : consumer.id, kind : consumer.kind, rtpParameters : consumer.rtpParameters, type : consumer.type, appData : producer.appData, producerPaused : consumer.producerPaused }); // Now that we got the positive response from the remote endpoint, resume // the Consumer so the remote endpoint will receive the a first RTP packet // of this new stream once its PeerConnection is already ready to process // and associate it. await consumer.resume(); consumerPeer.notify( 'consumerScore', { consumerId : consumer.id, score : consumer.score }) .catch(() => {}); } catch (error) { logger.warn('_createConsumer() | failed:%o', error); } } ``` // NOTE: Don’t create the Consumer if the remote Peer cannot consume it. Those lines of code would return directly without any logging, I don’t know any more details about the logic, maybe all the information above can help diagnose this issue and fix it. ---

Not too often as visit the v3demo sometimes With poor connection I used the KITE framework for auto testing the v3demo also found the issue happened Even I update the code to the latest the issue is not fixed ---

And when that happens, have you checked if it’s due to lack of RTP? or lack of video keyframe? or decoding issue? or lack of available downlink bandwidth so mediasoup decides to not send RTP and emits num spatial and temporal layers in that video consumer? ---

@universeroc with all respects, this is the **Leeryver Symptom** (in Spanish _“Leer-y-ver”_, in English: _“Read-and-see”_): _“I never check the logs when things go ok so, when things are not ok I check the logs for first time and assume that the first warning/error log is the cause of the problem.”_ All the logs you have pasted above **also** happen when video works. So instead of looking at random logs and suspecting from them, please try to focus on the questions I did (you did not check any of them in your last two comments): > And when that happens, have you checked if it’s due to lack of RTP? or lack of video keyframe? or decoding issue? or lack of available downlink bandwidth so mediasoup decides to not send RTP and emits num spatial and temporal layers in that video consumer? The mediasoup-demo app comes with a interactive terminal in server side. Run the demo server with: `$ MEDIASOUP_LISTEN_IP=YOUR_BINDING_IP INTERACTIVE=true DEBUG="*WARN* *ERROR*" ./server.js` then get the video Consumer `id` of the failing video (you can see it over the peer view in the web app), goto the server interactive console, run `terminal`, then type `dumpConsumer ID` and `statsConsumer ID` and paste the output. Also try clicking into `Request keyframe` in the failing received video to see if that fixes the issue and video comes in. ---

Well, I think I should explain how simulcast and bandwidth estimation works. We don’t send **everything** to remote endpoints. If videos use simulcast/SVC we just send the layers that fit into the downlink bandwidth that mediasoup has currently estimated for that endpoint (which changes dynamically). **And this includes the possibility of not sending any layer of a specific video because there is no bandwidth for it**. - How many simulcast videos are you consuming at the same time? or in other words, how many peers with webcam enabled are there already in the meet? - Which spatial/temporal layers are other working videos being receiving while others fail? - Does the “Request keyframe” button work for failing videos? (I asked this before). ---

There is an `initialAvailableOutgoingBitrate` in [WebRtcTransportOptions](https://mediasoup.org/documentation/v3/mediasoup/api/#WebRtcTransportOptions) to mitigate that. Everything is documented. I’m afraid that the demo app cannot just be taken as the “mediasoup reference app”. It’s not ready for **all** scenarios. ---

I know and I read some posts about the demo. Right now I’m doing some tests on the demo for example how many streams it can hold on a 4Core server. This issue prevents me to continue, mediasoup is a great project as using C++ and JavaScript both I love and code has high quality but its API is too low to start quickly as it’s only a library. Your demo is amazing to launch and to experience the mediasoup, more examples would be welcome. I’d like to contribute to this project after I master the basic usage. I’ll try something else to solve this issue, it’ll be solved saving more time under your help. Thank you for your patient and your reply 🙂 ---

> [@universeroc](#): > > I’ll try something else to solve this issue, it’ll be solved saving more time under your help The thing is: you assume there is an issue. I said that there may not be any issue. Please try using a higher `initialAvailableOutgoingBitrate`, use something like 20000000 (20 mbps) just to confirm that everything is about BWE. ---

You’re right, it’s not an issue before it’s confirmed. This morning I checked the client log and found the transport diconnected after connecting, dived into mediasoup-client code and saw the event source is from ICE. Doing another experiment and found that UDP port is not work, the final source is the network policy. I changed the MEDIASOUP\_MIN\_PORT, MEDIASOUP\_MAX\_PORT to be in the valid range then everything is OK. 😃 Thank you @ibc and sorry for wasting your time and attention. BTW: all your advice I’ve taken and modified. ---
