I have two laptops, one of around 2010 and another from 2018. Both go to almost 100% CPU with just two people in the Jitsi conference; with three people the sound stutters (because power is over 100%) and it becomes impossible for me to follow the conversation - even with camera disabled. I don't know how to disable the video entirely.
Click the "..." ("More settings") menu (in the bottom), then "quality settings", and set it to "low bandwidth". (The wording might differ since I see all this in german.)
There is video quality, but no bandwidth setting. Video quality I can drop to standard instead of HD, CPU load drops. But as soon as I connect with myself on the tablet, CPU goes up again. Ah! In video quality, the lower setting is "low bandwidth", but this one disables the camera at all. In this setting, I do not see the video of other people and CPU load remains low. Well, it is a solution if the tablet fails.
I can confererence using other solutions, like google meet or zoom. It is definitely a Jitsi problem.
Just wondering - which browser do you use? I usually use Chromium for video conferences which works quite well.
Normally firefox, but I tried Chrome.
OTOH, I've seen Firefox (my everyday browser) eating up lots of memory when using it for video conferences. In one case it ate up _all_ memory and I had to do a hard reboot to unblock the laptop. (That also means: keep an eye on the memory usage, not only CPU.)
Well, memory use is always high with FF... didn't check with jitsi in particular. Opening the FF task manager (about:performance), a youtube tab (not running) has double ram impact, but jitsi has a higher "energy" impact. This time I will try with the tablet first, it must be different code.
BTW: My laptop is now > 5 years old. I can estimate how many people are in a conference by listening to the fan ;-) Besides this annoyance, it works even in bigger conferences, like Jitsi meetings with up to 30 people.
My guess is there is some resource my CPU doesn't have that impacts load. Video card? Mine is integrated intel. -- Cheers / Saludos, Carlos E. R. (from oS Leap 15.2 x86_64 (Minas Tirith))
