Usage:
  -d, --device <dev> use device <dev> instead of /dev/video0
  -h, --help         display this help message
  -K, --passthrough <mode>
                     set passthrough mode: 1 = on, 0 = off [IVTV_IOC_PASSTHROUGH_MODE]
  --get-yuv-mode     display the current yuv mode
  --set-yuv-mode mode=<mode>
                     set the current yuv mode:
       		     mode 0: interlaced (top transmitted first)
       		     mode 1: interlaced (bottom transmitted first)
       		     mode 2: progressive
       		     mode 3: auto
  --reset <mask>     reset the infrared receiver (1) or digitizer (2) [VIDIOC_INT_RESET]
