Video4Linux in the videotexture

I’m trying to get video4Linux to output to the videotexture. According to the wiki this is possible, but it doesn’t say how. I tried switching the source to /dev/video0 (this is a webcam in my laptop, it works perfect in cheese and skype, so it is not a driverproblem). If I switch the source to an avi and ad =-1  

it all works well. But /dev/video0 gives me nothing. What am I doing wrong? This is my code:

import VideoTexture 
contr = GameLogic.getCurrentController() 
obj = contr.owner 
if not hasattr(GameLogic, 'video'): 
    matID = VideoTexture.materialID(obj, 'IMVJWall') = VideoTexture.Texture(obj, matID) 
    movie = '/dev/video0' = VideoTexture.VideoFFmpeg(movie) = True 
if hasattr(GameLogic, 'video'): 

I had trouble getting my /dev/video to work in blender… In fact I wasnt able. my driver for my web cam uses v4l2 and video4linux. Skype and cheese also work for me. I would love to figure this out but I may just have to get a different web cam. Blender uses video4linux for the ffmpeg web cam.
