Create Root Key

Attention: this is the key used to sign the certificate requests, anyone holding this can sign certificates on your behalf. So keep it in a safe place!

In the first case with set encoding=utf-8, you'll change the output encoding that is shown in the terminal.

In the second case with set fileencoding=utf-8, you'll change the output encoding of the file that is written.

## How to stream video from Raspberry Pi camera and watch it live.txt
The solution suggested by Diego is good except that it's pretty slow and has a huge video delay since the vlc there re-streams a stream of the raspvid. Since 12/2013 there is an official v4l2 driver available: http://www.ics.com/blog/raspberry-pi-camera-module#.VJFhbyvF-b8 This renders the mentioned re-streaming obsolete. Simply load the module and use it:

    sudo modprobe bcm2835-v4l2
    cvlc v4l2:///dev/video0 --v4l2-width 1920 --v4l2-height 1080 --v4l2-chroma h264 --sout '#standard{access=http,mux=ts,dst=0.0.0.0:12345}'

This creates an http stream at port 12345, you can use other formats too, like the rtcp one from the Diego's answer. Read more on it here: https://web.archive.org/web/20151012014829/http://www.videolan.org:80/doc/streaming-howto/en/ch03.html
