DebConf20 has been held online for the first time, due to the coronavirus (COVID-19) disease pandemic.
All of the sessions have been streamed, with a variety of ways of participating: via IRC messaging, online collaborative text documents, and video conferencing meeting rooms.
With more than 850 attendees from 80 different countries and a total of over 100 event talks, discussion sessions, Birds of a Feather (BoF) gatherings and other activities, DebConf20 was a large success.
When it became clear that DebConf20 was going to be an online-only event, the DebConf video team spent much time over the next months to adapt, improve, and in some cases write from scratch, technology that would be required to make an online DebConf possible. After lessons learned from the MiniDebConfOnline in late May, some adjustments were made, and then eventually we came up with a setup involving Jitsi, OBS, Voctomix, SReview, nginx, Etherpad, and a newly written web-based frontend for voctomix as the various elements of the stack.
All components of the video infrastructure are free software, and the whole setup is configured through their public ansible repository.
