My setup - vanilla leap 15.2 with a Microsoft USB camera+microphone, two speakers connected with the normal minijack, a regular desktop machine, with KDE and Firefox. At first, I think I had to install pulseaudio-something, I think Gertjan suggested it.
This has worked well with meet.o.o, with Cisco webex, with gotomeeting and with zoom.
My problem is unsolvable by me.
Laptop 1: CPU goes 100% and sound stutters. The meet system refuses the internal camera, "camera does not support required video resolution".
That is a Jitsi error message. If you google it, one suggestion is to go to https://test.webrtc.org to check out your hardware. I just did with my laptop, and it complained the microphone was not working or the volume set too low. For instance.
I'll try that. Laptop 2. Microphone passes. Camera passes at 320*240, gets stuck at 640*480. Prints a small progress green line that stops at the end where it should say "ok". Doesn't do any more testing. Cpu load is 8 by pulse audio. Camera led is now off. Laptop-1 on wifi. Camera fails at 1280*720, network warning at ipv6, connectivity warning because "reflexive connectivity" video bandwidth throughput fails. Laptop-1 on eth. gets stuck when testing camera at 640*480, same as laptop-2 Restarting the test passes that point: Camera fails at 1280*720, network warning at ipv6, connectivity warning because "reflexive connectivity" video bandwidth throughput fails. No improvement. Video throughput says it failed because "frame rate mean is 0, can not test bandwidth without a working camera". Retesting laptop-2 Laptop 2. Microphone passes. Camera fails at 1280*720. Network warning, no ipv6. Video thorughput fails, same problem as laptop-1
Plus, I don't have a working earphones for it (single jack), and BT earphones are unusable.
You don't actually need them, the speakers will do just fine.
In my experience, they tend to work badly. I know that on laptop-2 the integrated microphone in the past captured the noise of the hard disk and the fan. Without a loopback test, this is impossible to know. Skype had it. On laptop-1, the speakers are bad quality, so I need earphones on it in order to understand people.
Laptop 2: CPU goes 90%, so it copes (barely), but the meet system refuses my camera, "camera does not support required video resolution".
My hunch - those two are related. What happens if you just disable the camera, in jitsi ?
Then no camera, I guess. Ah, you mean the cpu load? no, no change. I played a lot with camera settings, no difference.
Someone has to explain to me what is the problem with the camera resolution and why does CPU power skyrocket.
It's very difficult to do with so little information.
I have never used meet, I don't know what is necessary. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)
