Octoprint ffmpeg stream script

To get started copy constants.example.py to constants.py:

$ cp constants.example.py constants.py

Afterwards make stream_start.py and stream_stop.py executable:

$ chmod +x stream_start.py
$ chmod +x stream_stop.py

You can now start the stream by simply running

./stream_start.py

and stop the stream with

./stream_stop.py [wait_seconds]
