cam.capture always undefined

Hello,
I am in need of integrating web cam and access its audio/video streams in IE. I have tried your shim and it works fine up to a certain point.

In getUserMedia.js, line no 103, [here](https://github.com/addyosmani/getUserMedia.js/blob/a0f839a214f1143a66b44410804fbb1c1e712158/dist/getUserMedia.js#L103), there is a condition where you check if the `capture` is not undefined. In my case, it always becomes undefined .

I have console logged that particular element and it looks like this:
``

Is there any particular reason why this is happening? Am I missing something? Please help me on this.

Thank you
