prlanzarin f74c7d4d0a fix(webcam): client intermittently crashes when sharing camera 
Under some specific scenarios, the virtual background restore code might
kick in _before_ the preloaded MediaStream is actually assigned to the
peer instance. That causes a crash because the peer attachment code
(where the vbg restore is triggered) tries to access the device ID of
said MediaStream - and it is undefined in the first place because it was
only being set in after the initial offer is generated which is an async
procedure.

This commit guarantees a preloaded stream is set before the peer is
flagged as created - so it's accessible by the attachment code.
It also checks whether there's a MediaStream available when trying to
restore VBGs to prevent undefined behaviors.

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/.
