what it is

An IRSSI connected to the #nurds channel on oftc on a big TV that was found in the rain outside at the trash.

urls etc

• http://10.208.30.111:8080/stream.mpng high res, uses more bandwidth

• http://10.208.30.111:8080/stream.mjpeg same res :-) but with jpeg artifacts and hopefully less bandwidth usage. might also be more compatible with all web-browse devices out there

• http://10.208.42.159:8070/stream.mjpeg?inst=terminal-stream if you want to see the images pasted in the irc-channel as an overlay (2 fps)
• http://10.208.42.159:8071/stream.mjpeg?inst=terminal-stream if you want to see the images pasted in the irc-channel as an overlay (15 fps)

• login with ssh (user nurds and well known password) into 10.208.30.111

• you can also stream a video-stream to it via multicast on address 239.168.0.1 port 11000
  • e.g.: gst-launch-1.0 v4l2src ! videoconvert ! video/x-raw, format=YUY2 ! jpegenc ! rtpjpegpay ! udpsink host=239.168.0.1 auto-multicast=true port=11000

how it is configured

display

• raspberry pi 1 directly connected to a tv
  • runs: mplayer from .profile started by 'nurds' user
  • SD-card is mounted read-only(!)
    • https://gist.github.com/nicokaiser/08aa5b7b3958f171cf61549b70e8a34b without the overlay part
  • ip address: 10.208.30.14

backend

• container (10.208.30.111) on coherence runs the backend - user irctv
  • termcamng listens on telnet and ssh
    • port 2300 for telnet, port 2200 for ssh
    • port 8080 for the png-stream
    • telnet has *no* authentication, ssh authenticates (via pam) against the local user-file
    • ssh/telnet bring you into the irssi session where you can interact with it

• on the ticker pi:
  • constatus listens on port 8070
    • http://10.208.42.159:8070/stream.mjpeg?inst=terminal-stream
    • constatus currently listens on the mqtt feed "irc/urls/#", see /home/constatus/constatus/termcamng.cfg

• on egg:
  • there should be a user irc2mqtt in the irc channel
  • that user is irc-to-mqtt.sh and .py on egg, runs in user flok. should be migrated to r3boot's bot.
