将数据附加到simpleWebRTC房间或视频

I'm using simpleWebRTC for a multi-party video chat.

Each user creates his own room. When a user subscribes to another (in order to see this person 0 and registers in the db).

When a user chooses another - he gets this users username by XHR from the db.

I tried adding the data for the appropriate video (or room) - under the

webrtc.on('video added'......

Is there another way I can attach data to the video or room which is more reliable?

This was just added very recently. You can now set nick on the config options passed to the constructor, which will be included in onVideoAdded -

var webrtc = new SimpleWebRTC({
     ... // your options here
     nick: 'my-user-id'
});

webrtc.on('videoAdded', function (peer) {
    //peer.nick is the other user's nick, and for them, this is yours
});
