Hopefully we can write here some summary of the findings in the webconferencing openspace session and #av-clubroom discord discussion at EuroPython 2020.
Hardware

Function:
- standard webcam for PC
Pros:
- just works with linux, e.g. with guvcview on ubuntu 20.04
- available, ca. 49 EUR
Cons:
- 65 degress wide angle (so little of "you" in lots of "room around you")

Bluetooth Adapters
1Mii USB Bluetooth Audio Transmitter B10 EAN X0014UJEH3
Function:
- for computer it is just a USB "sound card"
- internally, it transmits sound output via BT5 to headphones speakers
- internally, it receives sound input via BT5 from headset microphone
- 2 modes, switch by hw button:

- call - lower quality - input/output
Pros:
- keeps all the BT stuff away from computer
- nice for Qubes OS (just forward USB device to VM with teleconf sw)
- nice for Linux and BT5 (not [m]any working BT5 adapters yet)
- some stuff "just works"
Cons:
- lots of states signalled via single multicolor LED
- misc. state changing inputs via a single hw button
- no "debugging" possible if something BT does not work
Software
Linux Webcam Software
guvcview
- just works on Ubuntu 20.04
- quite some settings / adjustments for camera
- good video quality
OBS Studio
Pro:
- packages for Linux, old .deb package + recent snap for Ubuntu 20.04
- powerful processing / mixing / assembling of video output signal from misc sources
Con:
- to emulate a virtual webcam (which then can be used by your video conf software)
- you need an extra plugin and a kernel module and you might need to compile some stuff.
