The goal was to show a prerecorded video and do live Q&A (with camera)

• I used GNU/Linux Ubuntu 20.10 on X11
• built custom obs to enable v4l2loopback
• unpluged real webcam
• modprobe -v v4l2loopback
• pluged real webcam
• start obs
• obs / create scene : window capture (I captured Firefox window set as fullscreen)
  • optinnaly add some text, , add videocapture (real camera)
• obs/ desktop audio : -8.5 db & mic/aux : -2.2 db
• firefox/ show content (i played an existing video from peertube in Firefox)
• PulseAudio Volume/ Obs Monitor : notmutted, not locked , 110%

Then I am joining the WebRTC conference (ie: jitsi)

• camera to share : dummy video device 0x0000
• microphone to share : Monitor of Buildin Audio analog stereo
