[whatwg] Stream API feedback

A typical video chat application would contain some view finder code similar to 
the example in the Working Draft document:

<p>To start chatting, select a video camera: <device type=media onchange="update(this.data)"></p>
<video autoplay></video>
function update(stream) {
   document.getElementsByTagName('video')[0].src = stream.url;  }

But assuming that the Stream is a combination of both audio and video media this is
actually not what you want in a video chat, because you will also play back your own 
audio to yourself.

To solve this in our implementation we defined two fragments, "audio" and "video", 
for the Stream url. The application then can address a specific media component 
in the Stream like this:

document.getElementsByTagName('video')[0].src = stream.url + "#video";

Is there some other way to solve this?

Anyone curiuos can find more information on what we have been experimenting with here:
