Changes
== Current issues ==
* The telepresence part dosen't work* OK Accelerated video decoding and display on the Raspi
* PTL outgoing bandwidth
* Build a wooden window-like frame with curtains
* gstreamer-omx crashes way too often!
* We're now using [https://www.linux-projects.org/uv4l/ uv4l] instead of gstreamer and it looks quite promising!
== Hardware ==
* 2 (4?) Raspberry PI
* 2 Camera modules
* Custom printed box

=== Server ===

$ sudo raspivid -p 0,-100,500,500 -t 0 -o - -w 1280 -h 720 -fps 25 -b 1000000 | cvlc -vvv stream:///dev/stdin --sout '#rtp{sdp=rtsp://:9000/}' :demux=h264

Do do not forget to firewall access to the service!

$ omxplayer -o hdmi -s --live rtsp://1.2.3.4:9000/

== Automation with Puppet == The basic idea is to develop are shared puppet recipe hosted in a git repository to allow multiple raspi managed by different entities to all share the same verified configuration. This will hopefully provide insurance that the system really works point-to-point and that there's no way to spy in-between.
=== Setup from scratch ===
<pre>
$ whoami
pi
$ sudo apt-get install -y puppet
$ git clone ssh://gitolite@git.fixme.ch:1337/telepresence # send your ssh public ssh to François
$ sudo ~/telepresence/run.sh
</pre>
=== Logs ===
All puppet run results are sent to a publicly accessible e-mail address.
