Can you also paste the remote SDP offers generated by libmediasoupclient? I mean all SDP offers and answers, not just the failing one.

BTW are you using custom `PeerConnection::Options`?

@jmillan do you see anything wrong above? I don’t. We are extremely sure that Unified-Plan is enabled, right?

May I know why you have marked as “solution” my answer? It was just an answer.

BTW can you comment in a new answer instead of editing the original topic?

Sorry ， I accidentally checked it. I have not solved yet.  
I can’t show all the loggings , because of new user was forbidden to show "more links. "

Can you refresh the web and try again? BTW don’t forget to paste remote SDP offers.

Can you also uncomment the following line in order to get more logs from libwebrtc.

Are you using any `options` when calling to `recvTransport.Consume()`?

The issue is reproducible easily as shown in a new added [unit test](https://github.com/versatica/libmediasoupclient/commit/405b98c6e21bb39acd00f1033b0b2ba5babd7aef). Let’s move to a GitHub issue here:

</div>

There is no issue:

> <https://github.com/versatica/libmediasoupclient/issues/57#issuecomment-525068814>

So I expect that, in your case, you are eventually passing same remote Consumer parameters to `recvTransport.Consumer()` (as explained in the GitHub issue).

I pass the remote Consumer parameters by receiving the “newConsumer” msg content.  
void RoomClient::PorcessNewConsumer(nlohmann::json newConsumer, int msgId) {  
if (newConsumer.find(“id”)  
== newConsumer.end()) {  
std::cout \<\< “‘id’ missing in response” \<\< std::endl;  
return;  
} else if (newConsumer.find(“producerId”)  
== newConsumer.end()) {  
std::cout \<\< “‘iceParametersd’ missing in response” \<\< std::endl;

```
	return;
} else if (newConsumer.find("kind")
		== newConsumer.end()) {
	std::cout << "'iceCandidates' missing in response" << std::endl;

	return;
} else if (newConsumer.find("rtpParameters")
		== newConsumer.end()) {
	std::cout << "'dtlsParameters' missing in response" << std::endl;
	return;
}
std::string peerId = newConsumer["peerId"].get<std::string>();

std::list<struct Participant>::iterator iter;

```

// struct Participant participant;  
// participant.setPeerId(peerId);  
// iter = std::find(participants\_.begin(), participants\_.end(), participant);  
int channel;  
iter = std::find\_if(participants\_.begin(), participants\_.end(),  
[&peerId](decltype(\*(participants\_.begin())) & vt){  
return (strcmp(vt.peerId.c\_str(), peerId.c\_str()) ==0);  
});  
if (iter != participants\_.end()) {  
channel = iter-\>idx;  
} else {  
std::cout \<\< “can not find the peer information” \<\< " : peerId " \<\< peerId.c\_str() \<\< std::endl;  
return ;  
}  
recv\_transport\_-\>Consume(/_channel,  
this,_/  
this,  
newConsumer[“id”],  
newConsumer[“producerId”],  
newConsumer[“kind”],  
&newConsumer[“rtpParameters”]);

I use the newest libmediasoup-client version from github , but the issue still exists.

Please print the id and rtpParameters of all new consumers until it fails.

Ok, we’ll reopen the [issue in GitHub](https://github.com/versatica/libmediasoupclient/issues/57) to handle this issue, although right now I’ve no idea of why it happens in your case.

Please, subscribe to the issue in GitHub and track it for notifications.

This problem is easy to reproduce, use the browser to open two the same url（EG. [https://10.0.31.174:3000/?roomId=9nhl6r9k）](https://10.0.31.174:3000/?roomId=9nhl6r9k%EF%BC%89), and then manually start a client (libmediasoupclient), then receive the peers, and then process each peer’s newConsumer message, when processing By the time of the third newConsumer message, the program will have a probabilistic crash.

Can we please move to the GitHub issue?

Also, can you share your libmediasoup based app that connects to the mediasoup-demo server and consumers all producers? (please answer in the GitHub issue so we track the bug there).
