In these times of social distancing (due to the virus), online activities become even more important. What free and open-source tools are there to facilitate online events (for example online conferences)?
I have seen (and tested) so far Jitsi and BigBlueButton (for example see: https://bbb.fs.al). It seems that Jitsi is more suitable for informal meetings, while BBB is more suitable for presentations, lectures, webinars, online conferences, etc. And it is also very easy to install and setup (although a bit outdated).
Another system that I have tried is https://opencast.org . It was very easy to install (with docker-compose) but I couldn’t figure out how to use it properly (for example how to live-stream a conference).
I just wanted to share my experience (so far) and get any feedback from people who might have more experience with organizing online events or with live-streaming events.
