I love Jitsi, before Covid19 I never used it, now I use it daily for calls with family and yesterday I watched a video of our 4x4 trip with friends together with them (5 guys), streaming it from YouTube into the group chat. It worked very well.
We tried Jitsi Meet as a back-up for Google Meet in our company for the daily scrum, and it works great. The only nit-pick is the Firefox performance bug, but it's not too demanding to use Chromium for now just for Jitsi Meet until that bug gets fixed.
My colleagues loved the Youtube playback ability (I put on some elevator muzak waiting for the rest to join), although I had to do a bit of hunting to get rid of the video again. :)
Doesn't this make jitsi meet _effectively_ chrome only until they better support firefox/safari/etc[2].
[1]: I get "It looks like you're using a browser we don't fully support....We recommend to try with the latest version of Chrome or Chromium" when trying to use it.
[2]: Sounds like webrtc isn't well supported and fairly buggy for some browsers, apparently?
I use it in Firefox all the time with no difficulties. The only thing that doesn't work for me is selecting an external (USB PnP) microphone, but apparently that's due to a longstanding bug in Firefox that Jitsi is doing its best to work around.
In a previous discussion on HN about Jitsi, it was claimed that Firefox was missing some key aspect of the WebRTC standard that made sending video to multiple people more efficient; and that if a single person in the conference was using Firefox, the result would be a lot more CPU utilization for everyone.
So it "works" on Firefox, but the experience will be degraded when scaling up to more users. Hopefully FF can prioritize this feature now that the entire world needs high-quality video conferences on a regular basis.
Firefox works as well, but performance issues may arise when the number of participants increases. I've used Jitsi Meet with Firefox, and its fine one-on-one.
