The following works for me.
I'm not sure if there is any better way of doing it. I've empirically ended up with the following properties and function call orders:

- Before setting up the call:
core.videoPolicy.automaticallyAccept = true;           
core.videoDevice = $("#cam option:selected").text(); // selected combo box with available video devices
core.videoCaptureEnabled = true;
core.captureDevice = $("#mic option:selected").text(); // selected combo box with available audio capture devices

- After the call is established (state == 7):
// add the linphone video object to my #video div. This will call loadVideo when loaded
$("#video").append("<object id='remoteVideo' type='application/x-linphone-web-video'><param name='onload' value='loadVideo' /><param name='magic' value='1' /></object>");

- The loadVideo() function:
function loadVideo() {
    var v = document.getElementById('remoteVideo');
    var core = getCore();
    core.nativeVideoWindowId = v.window;               
    core.nativePreviewWindowId = v.window;
    core.selfViewEnabled = false; // change this to true if needed
    core.videoDisplayEnabled = true;   

Hope this helps

reposting to see if anyone has any thoughts on this. I am building my own linphone web client. I can make video calls from the browser, but I am unable to actually see the video call on my page. How do I get to display the video call? The video is definitely being captured and transmitted, because when I receive the call on linphone on my mobile phone, I can see the video call there.

So I've got to the point where I can login a user and initiate a call and receive a call. Some issues:

1. When the call is connected, my script does not seem to be capturing the microphone (on my mac) because I cannot transmit any sound (so not sure how to set my microphone to the call) or receive any sound (set my internal speakers to the call)

I tried doing this if my call state changed to 'Connected':
core.captureDevice = 'Built-in Input';
core.playbackDevice = 'Built-in Output';

but it does not help

2. My mac's camera does get turned on. On the receiving device, I am able to see myself from my mac's camera i.e. my browser is transmitting video. But I am not able to receive the video from the person I am calling i.e. I am not receiving  / seeing the video of the connected person on my browser. How do I enable display of this video playback?

Thanks Saumar, this could be really helpful. I'm going to give it a go.

In the linphone-web-plugin source, there's a folder doc/tutorials with basic html/js files.
I managed to write a simple web app using the following:
- tutorials folder
- source

I'm trying to build my own web page and use the linphone-web plugin. I've done web development before, but am not familiar with handlebars.js or how the current linphone JS code is structured.

Here's what I want to do when someone logs into my web app:
  1. Initiate the linphone object
  2. automatically log the user in to their linphone account (I have their credentials)
  3. On clicking a button, automatically dial a pre-determined SIP account
  4. Display the controls and video calling area in a custom div on my page
How do I initialize the core object so that I can use it persistently? 
What JS files do I need to include on my page to make this happen?
