There’s something fishy with the output though. It’s definitely not complete as the terminating ] character is not there.
Seems like android logging doesn’t really like strings longer than 1023. Finally, here’s the full SDP:

Device::GetRtpCapabilities() gives the computed capabilities after matching native ones and remote (Router) ones.
Please log private this->extendedRtpCapabilities generated in Device::Load().
This is the method with more debug messages:
void Device::Load(const json& routerRtpCapabilities)
{
MSC_TRACE();if (this->loaded)
throw Exception(“Already loaded”);
else if (!routerRtpCapabilities.is_object())
throw Exception(“Missing routerRtpCapabilities”);// Get Native RTP capabilities.
auto nativeRtpCapabilities = Handler::GetNativeRtpCapabilities();// Get extended RTP capabilities.
this->extendedRtpCapabilities =

MSC_DEBUG(“routerRtpCapabilities: %s”, routerRtpCapabilities.dump().c_str()); // added for debug
MSC_DEBUG(“this->extendedRtpCapabilities: %s”, this->extendedRtpCapabilities.dump().c_str()); // added for debug// Check whether we can produce audio/video.
this->canProduceByKind[“audio”] = ortc::canSend(“audio”, this->extendedRtpCapabilities);
this->canProduceByKind[“video”] = ortc::canSend(“video”, this->extendedRtpCapabilities);// Generate our receiving RTP capabilities for receiving media.
this->recvRtpCapabilities = ortc::getRecvRtpCapabilities(this->extendedRtpCapabilities);MSC_DEBUG(“succeeded”);

What looks weird to me is this (routerRtpCapabilities):

},
{

"type": "nack"
},
{

"type": "ccm"
},
{
"parameter": "", <------- ??
"type": "goog-remb"
},
{
"parameter": "", <------- ??
"type": "transport-cc"
}
]On the server:
Array(5) [Object, Object, Object, Object, Object]
length:5
proto:Array(0) [, …]
0:Object {type: “nack”, parameter: “”}
1:Object {type: “nack”, parameter: “pli”}
2:Object {type: “ccm”, parameter: “fir”}
3:Object {type: “goog-remb”, parameter: “”}
4:Object {type: “transport-cc”, parameter: “”}
No, this is not weird. It’s ok.
It’s the channels on the video (from router). I guess it should not be present.
Why not?
In https://github.com/versatica/mediasoup/blob/v3/src/RtpParameters.ts
/**
* The number of channels supported (e.g. two for stereo). Just for audio.
* Default 1.
*/
channels?: number;It’s ok if channels:1 for video. However not sure which versions you are using, there may have been changes regarding this recently.
Confirmed that this issue happens with libmediasoupclient 3.0.8 (latest release) and any previous version if mediasoup version is one of the latest.
Can you try libmediasoupclient v3 branch? Although I don’t know if it’s ready. @jmillan?
Setting channels to undefined on the server solved this problem.
I think you’re right, I should definitely update!
Thanks a lot for pointing out the debugging tips. It was a useful experience!
Sure, will do.
Wait a bit, there is ongoing work on it. You may try with an older version of mediasoup.

Try mediasoup 3.4.0 which was previous to those changes.
Thanks!
I have bellow code.
mMediasoupDevice.createRecvTransport(recvTransportListener, id, iceParameters, iceCandidates, dtlsParameters, null);
private RecvTransport.Listener recvTransportListener =
new RecvTransport.Listener() {
private String listenerTAG = TAG + "_RecvTrans";
@Override
public void onConnect(Transport transport, String dtlsParameters) {
Logger.e(listenerTAG, "onConnect()");
}
@Override
public void onConnectionStateChange(Transport transport, String connectionState) {
Logger.e(listenerTAG, "onConnectionStateChange: " + connectionState);
}
};
When “mMediasoupDevice.createRecvTransport” initialized it not call to “onConnect” or “onConnectionStateChange”. Can you help me haiyangwu?
Please, don’t add direct mentions.
onConnect will be called when you create your first Producer or Consumer.
Android native client can be used in unity?
