Command Line Options

Basic Options

• --help -h -?
  • Displays the help message, and exits.
• --verbose -v
• --out

HTTP Server options

• --port [port] -p [port]
  • This option sets the port that the HTTP server will run on. The port defaults to 5800, because reasons, so if you want to be able to connect to pi@raspberrypi.local, you will need to add -p 80 to your startup arguments.
• --jpeg-quality [quality]
  • Set the quality of the JPEG. Values are 0 to 100, inclusive, where 0 is the worst quality possible, and 100 is pretty good. Defalts to 80, which is standard. Don't drop this value to save bandwidth, because testing has shown that a drop in quality from 80 to 50 only saved about 1 or 2 kb/frame (out of ~105kb/frame). The test was conducted with the saturation control maxed out.
• --enable-gzip
• --no-server
  • Disable starting the HTTP server. Most other things should work still.

GPIO options

• --gpio-pin
  • Set the GPIO pin. Note that the pin numbers are based on WiringPi's (you can see a nice chart here).
• --no-gpio
  • Disables using the GPIO.

Processor options

• --x-skip
• --y-skip
• --save-diff
  • Save the differential image to a PNG.
• --no-process
