addStream | RTCMultiConnection

Use this method to add additional streams in a LIVE session.

Add camera and microphone

connection.addStream({
    audio: true,
    video: true,
    oneway: true
});

Add screen

connection.addStream({
    screen: true,
    oneway: true
});

Description

parameterdescription
audio share microphone
video share camera
screen select and share a screen
oneway only you will share; all others will merely receive it

Best practice

Always try to set sdpConstraints and mediaConstraints before calling "addStream" method:

connection.sdpConstraints.mandatory = {
    OfferToReceiveAudio: true,
    OfferToReceiveVideo: true
};

connection.mediaConstraints = {
    video: true,
    audio: true
};

connection.addStream({
    screen: true,
    oneway: true
});

Open data channels

You can enable text-chat or file-sharing in a LIVE video session:

connection.addStream({
    data: true
});

Share with single (unique) user

You can share with only one user rather than sharing with all connected users:

// runtime sharing of screen among two unique users
// one is you; and other is person whose id is given below
connection.peers['user-id'].addStream({
    screen: true,
    oneway: true
});

// if you want audio-only session
connection.session = {

};

connection.mediaConstraints = {
    video: false,

connection.sdpConstraints.mandatory = {
    OfferToReceiveAudio: true,
    OfferToReceiveVideo: true

connection.openOrJoin('your-room-id');

document.getElementById('share-video').onclick = function() {
    this.disabled = true;
    connection.mediaConstraints.video = true;
    connection.addStream({
        video: true,
        oneway: true
    });
