Hi guys,

Congrats on your webrtc tokbox release here at MashMeTV we started working a few hours ago ( btw yes in Spain is late VERY late xD ) and we have a testing version working with WebRTC.

It works great audio and video quality felt amazing, BUT is there a way to interoperate between the new webrtc version? and the old flash one?

Sadly no all MashMeTV users are using chrome (shame on them)

Thanks!

HI Victor! That was fast!! The current webrtc version does not fallback to flash (sorry!!!). I am going to copy paste this response on our blog from Ankur on my team, since it's better than anything I can say:

There is no automatic fallback right now. An earlier version of our Labs releases did support fallback from WebRTC -> Flash, but we decided doing without that helped to get the technology out there sooner and see how our developers actually used it. That fallback would detect if any single client that was connected didn't support WebRTC, then all connected clients would fallback to Flash, and therefore they were all in the same session. Sessions were not mixed. Right now the way to achieve this is exactly what you said: feature detect and load the appropriate library. Stay tuned, new features like this may land pretty soon as we learn more about users.

Thanks for the fast answer

I will wait then for some fallback solution in that matter or let's hope that all browsers provider put webrtc where it should be

PS: the fast implementation was actually pretty easy almost everything worked out of the box.

Regards

Hello, can't wait to implement the WebRTC version on our site, but we wouldn't implement it without fallback. Hope the feature comes soon!

Also looking forward to this - any ETA on interop? What's the current state of the art for mixing WebRTC and Flash clients, including selecting an OpenTok library based on their capabilities?

No flash-webrtc interop is planned anymore. There is not enough demand/ not enough resources to implement such a thing.

Sorry,
John

Since "No flash-webrtc interop is planned anymore" you can implement it by dynamically loading the right library:

<script src='http://static.opentok.com/webrtc/v2.0/js/TB.min.js' ></script>
<script type="text/javascript">var isVB = false</script>
<script LANGUAGE="VBSCRIPT">isVB = true</script>
<script type="text/javascript">
if (TB.checkSystemRequirements() == 0) //cannot use html5 chat, switching to flash - load a js lib for flash
{
TB = null;
loadScript('http://static.opentok.com/v0.91.63/js/TB.min.js', loadSolo);
}
else
{
//proceed with webrtc
loadSolo();
}

function loadSolo()
{
TB.addEventListener("exception", exceptionHandler); //and do whatever else you need to do
}

function loadScript(sScriptSrc, callback)
{
var scrWrapper = document.getElementById('scrWrapper'); //make sure you create this div in a page before the code executes
var oScript = document.createElement('script');
oScript.type = 'text/javascript';
oScript.src = sScriptSrc;
scrWrapper.appendChild(oScript);
if (!isVB)
{
oScript.onload = callback;
}
else
{ //for iE
oScript.onreadystatechange = function()
{
if (this.readyState == 'complete')
{
callback();
}
};
}
}
</SCRIPT>

Just make sure the browsers understand the same media file type - use canPlayType.
All the best,
Peter
