WebCamTexture problems

Hello,

I use Unity 3.5.5
I try to use that component with iOS and have several problems regarding the genericity of that component :
- on iOS WebCamTexture.requestedWidth and WebCamTexture.requestedHeight don't seem to function since the video ratio is ever the same
- on iOS WebCamTexture.width and WebCamTexture.height ever return me the value '16' so they seem to get bugged
- on iOS the camera texture is flipped and in landscape mode and I have no clue how to figure that appart from empirical conclusions,
- on Android the camera texture is in landscape mode and again I have no clue of how to figure that
- on OSX the camera is in portrait mode

So my question is : is there any clue appart from empirical heuristic and if not is Unity4 better about that ? Or do I need to develop on my own that component and port it to have a proper one ?

Thank you.
