Streaming setup in initLab

Currently, we're running the FOSDEM VideoBox 2.5 with the simplified setup (see [1] for the ansible recipes, [2] for an overview of the box).

How to stream a talk

Box setup

• Connect the video-box HDMI loop out to the projector
• point the projector properly to the screen
• Connect the USB camera to the USB host port on the videobox
• Connect the microphone receiver to XLR port IN2 of the videobox
• connect the power of the microphone receiver to one of the power ports of the box
• connect ethernet port to the videobox
• Power-on the videobox

Speaker setup

• Connect the speaker's laptop to the HDMI IN of the video-box
• Make sure you can see the preview of the speaker's screen on the projector and on the display of the videobox
• Put the lapel mic on the speaker
• Power on the mic transmitter and mic receivers and make sure they've linked
• Check at https://video-box-ip/vocto.php if you can see things correctly and that the audio level is correct
  • The IP is visible on the display of the box

Before starting the talk

• The following can be also done remotely by either krokodilerian or Slackware
• Enable recording on the box (systemctl start video-recorder)
• Start pushing to streamer (in tmux, bash /opt/scripts/push-yt.sh RTMPURL)

During the talk

• Monitor the stream if everything is ok

=== After the talk

• Recording/streaming part
  • Stop streaming and recording
  • Copy off the recording from the box
  • As noted, krokodilerian or Slackware can do that remotely
• Power-off the microphone receiver and transmitter
• Connect the microphone transmitter to charge
