What URL config parameters can be used to prefer or force a custom average video bitrate?

Any Jitsi meeting appears to average the bitrate of any one webcam stream approximately 1,200kbps, which even in VP9 is full of video compression artifacts.

What URL config parameters can be used to prefer or enforce a custom average bitrate?

Also, despite WebRTC already adding support for realtime AV1 and implementing it in Chrome, is it still not possible to prefer AV1 codec in Jitsi Meet yet?

You can override the following config option: jitsi-meet/config.js at d40aecb05db7dd85ebc5e91832d4a3dadd5b88b7 · jitsi/jitsi-meet · GitHub

It’s being worked on.
