Your issue is lack of information, It would be nice to have more details of what you did, SDP offer and answer..

But I think I know what is the problem, I've already opened an issue for myself and I think it will fix the problem.

Ho did you used the code, did you change anything?

ghost commented 6 years ago

Firstly I use this build https://github.com/kirushyk/kms-windows Did't change code, only hosts.. I'm trying to get PCMU

givo commented 6 years ago

Can you share the all output?

It seems that " get waiting candidates from FIfo " function runs in parallel to the main "loop", this isn't suppose to happen... weird

in Chrome the situation is more interesting, but the sound doesn't come to the browser kurento_log server_log browser_log

givo commented 6 years ago

Man, you have to look in the example's code, you missed a very important little thing:

You have to change offerToReceiveAudio to 1 in the last row in client.js:

webRtcPeer.createOffer((offer) => onLocalOfferCreated(null, offer), (err) => onLocalOfferCreated(err, null), { offerToReceiveAudio: 1, offerToReceiveVideo: 1 });
}
ghost commented 6 years ago

Yes, of course, I changed it long ago, so the problem is something else

givo commented 6 years ago

Did you reconfigure your encoder to transmit audio to the udp port that Kurento described in the sdp answer after the session started and a FLOWING event recevied?

ghost commented 6 years ago

Yes

givo commented 6 years ago

What is the red OK message that is shown in chrome's console?

Please try the following steps:

ghost commented 6 years ago

Firefox asked me to add the second argument 

webRtcPeer.addIceCandidate(parsedMsg.candidate, function(err)...
webRtcPeer.addIceCandidate(parsedMsg.candidate, function(){console.error('OK');}, function(err)...

Yes, offerToReceiveVideo was setting to 0. Will try to use audio tag.

givo commented 6 years ago

Yeah I didn't try this example on firefox, only on chrome..

givo commented 6 years ago

I understand that using the audio tag did the trick?

ghost commented 6 years ago

Sorry, I can check the audio tag only tomorrow.

ghost commented 6 years ago

No, the audio tag is not working.

givo commented 6 years ago

The only thing I can think of is playing in the client side code and html. Find out what is the codec kurento is sending the configure the audio tag properly.

ghost commented 6 years ago

I don't know how I can config the audio tag if I'm sending PCMU..
