How to combine ofxWMFVideoPlayer with ofxCv

Hey,

I was trying to find contours in a video with ofxCv, which is loaded and played with ofxWMFVideoPlayer. I don't get any results. It also seems that "video.getPixels()" is returning an array full of grey pixels.

Is there any easy way to get color values of the pixels or to make the played video readable by ofxCv?

Thanks a lot!
Tobias
