Re: Re: Using <cvSetCaptureProperty> to set webcam resolution
Thank you for your suggestion. I think it is a bug in Opencv and we would have to get around it like you recommended.

The solution for me is to resize each image from camera by myself
instead of using cvSetCapturePropert y.

However, this was written for earlier version of Opencv, whereas I am
using the latest 1.1.0 version. Does anyone know how to solve this
