Problems with QCamera

[MCMic]

Hello!

I’m working on a photobooth application : http://projects.haxx.es/p/qphotobooth/
I’m using Qt Multimedia for this and I’m having some problems:

• The method «QCameraImageCapture::supportedResolutions» always give me an empty list
• With my integrated laptop webcam when capture is called the video freeze for 2 or 3 seconds before the pic is actually taken
• With an external cam video is fine but pics taken are all gray

Both cams works fine with cheese. Isn’t Qt using the same drivers?
Is supportedResolutions supposed to work?

not sure this is the actual code but in debug mode I do see CameraBinImageEncoder messages, and in this cpp it seems like the supportedResolution method is empty?
