I changed the format to V4L2_PIX_FMT_YUYV in uvccapture.c, and the
verbose output said it was taking a picture at 1280x960, but the image
it produced was a 4k file which, when opened with eog, had no height and
width (so there was no real image there, only headers). Is there
something else I need to do to get YUYV capture to work?
