Allow disable webcam for all
In large meetings we always have a couple of people, having the camera shutter closed but webcam is on. This results in streaming a blank screen. Additionally, in order to decrease bandwidth usage and focus on the speaker only, participants are asked to disable their webcam. Unfortunately there are always some people, who do not apply and ignore any notice over voice or chat. Similar to mute all, an option to deactivate all cameras would be great.
