this is what i did for setting up the VIDIOCSWIN:
struct video_clip vcl[10];
struct video_window vw;
vw.x=0; vw.y=0;
vw.width=640; vw.height=480;
vw.chromakey=1;
vcl[0].x=0; vcl[0].y=0;
vcl[0].width=640; vcl[0].height=480;
vw.clips=vcl;
vw.clipcount=0;
ioctl(fd,VIDIOCSWIN,&vw);
and i am still getting the error...
thanks,
