WebcamTexture always return "16" for width and height.

Hello,

I am really a beginner in Unity world, and struggling with webcam.

First of all, I am trying to get an image from my webcam with the code below,
and I get an error on WebCamTexture.GetPixels method and the issue looks here;

-----
WebCamTexture wct; // at the top of the class

wct = new WebCamTexture( ) // in Start( )
-----

this wct always returns 16 for width and height even I requested bigger image such as 1024x768.
Webcam looks working since it lits green light and I can see the cam image on the property pane which is not 16x16 sized image.
I read some similar posts, but always no answer there. Maybe I am missing something really important?
Please let me know your idea of what I should do... I am totally stuck with this...

I am working on Mac OS X (latest) and Unity 4.6, trying to make an iOS/Android app.

Thank you very much in advance.
