Hi, I'm using the bttv2 driver from bttv-v4l2.sourceforge.net, the release of June 2001, and I have a problem when I try to acquire only a filed of an image, es. the top field. I'm acquiring 352x288 images using the V4L2_PIX_FMT_YUV420 format. I also set the format flag V4L2_FMT_FLAG_TOPFIELD, but sometimes I acquire the even and sometime the odd field. My acquisition also switches the input channel of the mux. If I use the bttv 0.8.xx drivers in bttv2 mode it seems to work better, but I must use the bttv2 driver from sourceforge. Can someone explain me hoe to acquire better images... Thanks, Andrea -- Andrea Oddera oddera@xxxxxxxx http://www.aitek.it Aitek S.p.A. - Via della Crocetta 15 - 16122 Genova
