For C, you would do: struct video_channel vchan; /* set preferred input/norm. * for BTTV - 0 = tv tuner input, 1 = composite, 2 = svideo */ vchan.channel = 0; vchan.norm = VIDEO_MODE_NTSC; ioctl(fd, VIDIOCSCHAN, &vcan); I have no clue how this would look in whatever language you're using (Perl?), but I'm sure the idea is largely the same there.
