prlanzarin d350afd194 fix(screenshare): check packet flow to detect unhealthy streams earlier 
Screen streams were only deemed unhealthy when the transport's ICE state
transitioned to failed. That was as good as nothing because the stream would
stay frozen with no visual UI feedback until it reconnected. Bad UX.

This commit addresses that issue via two changes:
  - A stream is deemed *potentially* unhealthy now if the transport's
    state becomes disconnected
  - If a stream is deemed potentially unhealthy, a monitor probe is
    started to check whether there is media/packet flow (every 500ms).
    If there's no packet flow, the stream is flagged is factually unhealthy and
    UI feedback about that is rendered.

It's still not as good as it could be - relying on disconnected still
leaves a couple of seconds of silence to be dealt with. For that to be
addressed the prober would have to run nonstop, but that's for later.

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/.
