This is a rework of the audio join procedure whithout the explict listen
only separation in mind. It's supposed to be used in conjunction with
the transparent listen only feature so that the distinction between
modes is seamless with minimal server-side impact. An abridged list of
changes:
- Let the user pick no input device when joining microphone while
allowing them to set an input device on the fly later on
- Give the user the option to join audio with no input device whenever
we fail to obtain input devices, with the option to try re-enabling
them on the fly later on
- Add the option to open the audio settings modal (echo test et al)
via the in-call device selection chevron
- Rework the SFU audio bridge and its services to support
adding/removing tracks on the fly without renegotiation
- Rework the SFU audio bridge and its services to support a new peer
role called "passive-sendrecv". That role is used by dupled peers
that have no active input source on start, but might have one later
on.
- Remove stale PermissionsOverlay component from the audio modal
- Rework how permission errors are detected using the Permissions API
- Rework the local echo test so that it uses a separate media tag
rather than the remote
- Add new, separate dialplans that mute/hold FreeSWITCH channels on
hold based on UA strings. This is orchestrated server-side via
webrtc-sfu and akka-apps. The basic difference here is that channels
now join in their desired state rather than waiting for client side
observers to sync the state up. It also mitigates transparent listen
only performance edge cases on multiple audio channels joining at
the same time.
The old, decoupled listen only mode is still present in code while we
validate this new approach. To test this, transparentListenOnly
must be enabled and listen only mode must be disable on audio join so
that the user skips straight through microphone join.

BigBlueButton
BigBlueButton is an open-source virtual classroom designed to help teachers teach and learners learn.
BigBlueButton supports real-time sharing of audio, video, slides (with whiteboard annotations), chat, and the screen. Instructors can engage remote students with polling, emojis, multi-user whiteboards, shared notes, and breakout rooms. During the session, BigBlueButton generates analytics that are visible to moderators in the Learning Analytics Dashboard.
Presenters can record and playback content for later sharing with others.
We designed BigBlueButton for online learning, 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)
The latest version is BigBlueButton 2.7. You can install BigBlueButton 2.6 on Ubuntu 20.04 using bbb-install.sh within 30 minutes (or your money back 😉).
For full technical documentation of BigBlueButton -- including architecture, features, API, and GreenLight (the default front-end) -- see https://docs.bigbluebutton.org/.
