echo problem in audio/video chat application


echo problem in audio/video chat application

fixed the issue. Will look into that further Acoustic Echo Cancellation (AEC) is a particularly tricky problem in telephony, audio/video-conferencing, etc. Even if you're using a headset at your end you can still get echo via the remote end. You need an AEC module in your application otherwise you will need to ensure that both ends always use headsets. Unfortunately AEC is quite hard to implement - you can do something crude with an adaptive LMS filter but really good AEC tends to only be available as a licensable commercial solution.

Can we add audio/video chat functionality of GTalk inside our application

may help you . I'd love to answer, yes, but unfortunately gtalk is proprietary application and we are entirely at Google's mercy. Newer Honeycomb tables should have it, though.

I hope this helps you . Echoing can be solved by wearing headphones. Echos usually happen when the computer microphone driver doesn't support echo cancellation, when the microphone is too sensitive, the speakers are turned on too loud, or interference from other electronic devices nearby.

I think the issue was by ths following , finally I got it work! The first answer for question from this "webrtc video stream stop sharing" guided me to the right direction. I created two new functions to mute video and audio, and bound them to appropriate buttons in html file. And finally it became look like this:
code :
navigator.getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia;

var myStream;
var peer = new Peer({key: 'PeerJS key'});

var setOthersStream = function(stream){
  $('#others-video').prop('src', URL.createObjectURL(stream));
};

var setMyStream = function(stream){
  myStream = stream;
  $('#video').prop('src', URL.createObjectURL(stream));
};

peer.on('open', function(id){
  $('#peer-id').text(id);
});

peer.on('call', function(call){
  call.answer(myStream);
  call.on('stream', setOthersStream);
});

$(function(){
  navigator.getUserMedia({audio: true, video: true}, setMyStream, function(){});
  $('#call').on('click', function(){
    var call = peer.call($('#others-peer-id').val(), myStream);
    call.on('stream', setOthersStream);
  });
});

peer.on('error', function(e){
  console.log(e.message);
});

//create button to toggle video
var video_button = document.createElement("video_button");
video_button.appendChild(document.createTextNode("Toggle hold"));

video_button.video_onclick = function(){
  myStream.getVideoTracks()[0].enabled = !(myStream.getVideoTracks()[0].enabled);
}

var audio_button = document.createElement("audio_button");
video_button.appendChild(document.createTextNode("Toggle hold"));

audio_button.audio_onclick = function(){
  myStream.getAudioTracks()[0].enabled = !(myStream.getAudioTracks()[0].enabled);
}

will be helpful for those in need Yes, use the same connection, as it wont influence quality any more than a separate connection.
Just add:
code :
var dataChannel = yourPeerConnection.createDataChannel("chat");
var dataChannel = pc.createDataChannel("chat", dataChannelParams);

dataChannel.onmessage = function(event) {
    document.querySelector("textarea#receiveText").innerHTML = event.data;
};

hope this fix your issue You can go for a serverless real-time chat application with AWS. You can create separate Lambda Functions as microservices for textual and video conferencing. Then configure these lambda functions to be triggered by CloudFront Events. You can also check which type of events are being triggered in CloudFront and perform the desired function.
