prlanzarin e6e1f28036 feat(audio): channel threshold for transparent listen only activation 
Transparent listen only is currently only worth it for meetings with a
number of duplex audio channels larger than a certain value (dependant
on system performance). That is due to the fact that global audio
bridges created for the mechanism also use significant CPU (roughly the
same as an unheld duplex channel), which means it's cost is usually
offset only once there are enough potential channels to be held in a
conference.

This commit adds a new optional feature that introduces some dynamicity
for the mechanism: it'll only be triggered after at least
@voiceConf.transparentListenOnlyThreshold number of muted duplex
audio channels are present in a conference.
The default is 0 (always trigger transparent listen only if the general
mechanism is activated).

BigBlueButton

BigBlueButton is an open source web conferencing system.

BigBlueButton supports real-time sharing of audio, video, slides (with whiteboard controls), chat, and the screen. Instructors can engage remote students with polling, emojis, multi-user whiteboard, and breakout rooms.

Presenters can record and playback content for later sharing with others.

We designed BigBlueButton for online learning, (though it can be used for many other applications as well). The educational use cases for BigBlueButton are

  • Online tutoring (one-to-one)
  • Flipped classrooms (recording content ahead of your session)
  • Group collaboration (many-to-many)
  • Online classes (one-to-many)

You can install on a Ubuntu 20.04 64-bit server. We provide bbb-install.sh to let you have a server up and running within 30 minutes (or your money back 😉).

For full technical documentation BigBlueButton -- including architecture, features, API, and GreenLight (the default front-end) -- see https://docs.bigbluebutton.org/.
