If anyone has worked in greyscale (V4L) and > had good results please reply me. The examples of mine on Gleicon's site include working V4L greyscale capture with the bttv (Bt848) driver. Maybe the Creative webcam Plus hardware and/or driver doesn't support it. If you just want greyscale data (as opposed to wanting it for lower datarates), then just convert the RGB to YUV and use the Y - that's what the bttv greyscale is. There are a zillion RGB-YUV conversion routines out there, including a reasonably fast one in the tarball of mine on Gleicon's site. Ben
