Very nice! I have been looking at jitsi, nextcloud and BBB. I admit to using skype as well.Hi,In case anyone is looking for more secure alternatives to the commecial videoconferencing offerings... I've been doing my lectures over BigBlueButton. I'm very happy with it -- it's rock solid, scales to 70 people with no problem, and the user interface is well designed for lectures. Our system engineers say that it requires non-trivial server resources, though. One of the interns I'm working with recommends Jitsi. I have no personal experience with it. For my own needs (chatting with my parents and drinking beer with my friends), I've written a very simple WebRTC-based videoconferencing server that requires virtually no server resources and is very easy to install. It builds a complete mesh between the participants in a group (which is why it requires little server resources), so don't expect it to scale beyond a handful of participants, but it works fine for small groups (the maximum we've done was six, including the cat, who of course had his own webcam). https://www.irif.fr/~jch/software/chat/ (I know, I know, I should get my act together and release babeld 1.9.2 rather than hacking WebRTC.)
My results so far:* skype eats my CPU. Even when not videoconferencing one core is maxed out. This is a no-go. I have no trouble searching for alien life on my devices but for a chat-application not doing anything 100% CPU usage is too much. However when in use it is pretty seemless if you don't mind throwing another CPU core when doing video conferencing. And of course when using skype you mustn't care about privacy, FOSS et. al. * nextcloud: seems ok, especially in the latest releases. However there are connectivity issues and when the server is under load there is lag. I also get disconnects. The desktop sharing window is rather small on nextcloud too. * BBB: the most sophisticated, feature-complete and stable solution so far. I do recommend using that. The server-end is a bit involved as you *have* to have ubuntu 16.04 LTS running underneath. * When using it, VC works for 2-3 participants. From 5 onwards it a) melts my CPU and b) there is multi-second lag between audio and video.
* nextcloud, bbb and jitsi have the benefit over skype of not using any CPU while not using it. * I have tried linphone as well - it needs to be manually compiled in a recent version to contain the codecs required to participate in converences hosted on the DFN. I couldn't get it to compile.
BBB is the clear winner here. Given integration into an xmpp client this would be even more interesting.
