That looks like a format mismatch. Though the capture is pal resolution, the captured video looks like ntsc. When using v4l2-ctl simply setting the format to ntsc or pal should be sufficient for the capture to work. I think the same applies to v4lctl. Which version of the ivtv driver are you using? I've just done a quick test here using the current release and it seems to work fine when changing capture format. -- Ian _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
