This document gives you an overview of BigBlueButton 2.6, the latest version of BigBlueButton now in development.
Note: This document is DRAFT and will be expanded upon as 2.6 development goes through alpha, beta, and release.
BigBlueButton 2.6 offers users improved usability, increased engagement, and more performance.
- Usability - making common functions (such as raise hand) easier
- Engagement - giving the instructor more ways to engage students
- Performance - increasing overall performance and scalability
Here’s a breakdown of what’s new in 2.6.
BigBlueButton supports dark theme. To enable it just navigate to the Settings.
Improved Echo Test dialog
The echo test modal has added a new audio stream volume indicator in place of the separate confirmation screen. This reduced the number of views and interactions required for audio confirmation.
Improved notification of recording start
The indicator for whether the recording is on has been made bigger. Additionally if you create your meeting with an optional parameter
notifyRecordingIsOn=true, you users will see the following dialog when the recording commenses and also when joining a session that is already actively being recorded. You can choose to either continue or leave the session.
Allow pinning of more than one webcam
The pinning feature prevents the webcams from being rotated out when audio floor switching is activated. This functionality is specially important for document and/or interpreter cameras. It has also been improved to support miltiple pinned cameras.
Upload your own webcam background
This new feature allows a user to upload virtual background image’s for their webcam. The user can upload and delete images at will.
Set webcam image brightness
Allows the ability to adjust the brightness levels of their webcam (or) webcam and background image.
This is done via the webcam settings modal using the brightness slider at the bottom.
Improved layouts manager selection
Layout selection can now be done via the updated layout selection modal located in the actions (+) button.
Live Automatic Closed Captions
Note: The automatic transcription is only available for browsers that support SpeechRecognition (Google Chrome, MS Edge and Safari). So those who join a meeting using other browsers will see a warning in the audio modal.
By default, automatic transcription language selector is disabled. This can be changed in the settings file. Users who want to have their voices transcribed must enable it by selecting the desired language from the drop-down selector in the join audio dialog.
When the user selects a language for automatic transcription, BigBlueButton will display a CC icon next to their name in the “who is talking” indicator.
When one or more users have enabled transcription, BigBlueButton will display a ‘CC’ button to display the transcriptions. You don’t need to have selected transcription of your audio to view the transcriptions for others.
To view the transcriptions for those with ‘CC’ in their “who is talking” icon, select the CC button.
The placement of the ‘CC’ button depends on your device. For desktop, the ‘CC’ button is in the bottom left.
For mobile devices, The ‘CC’ button is in the three dots at the top right corner.
To enable the option for automatic translations for users of Google Chrome, Microsoft Edge, and Safari, edit the
/etc/bigbluebutton/bbb-html5.yml and add the following to the
public: section and restart BigBlueButton.
public: app: audioCaptions: enabled: true
Downloading presentation with whiteboard annotations included
Teachers can now export their slide decks with the annotations added during a lesson. Selecting “Send to chat” in the presentation upload modal sends a link in the public chat from which meeting participants can download the file.
Upload a presentation straight from NextCloud
Two new create parameters: uploadExternalDescription and uploadExternalUrl have been introduced.
The client supports these parameters, displaying a message in the presentation upload modal when both values are set at meeting creation.
Easier moving of users between breakout rooms
There is a new option for the breakout room controls called Manage users.
This dialog lets you drag-and-drop users between different breakout rooms.
When you click Apply, BigBlueButton well send prompts to each user to move them to the target breakout room.
Recording in MP4 format
This release will introduce a new recording format that creates a single video file from audio, video, screen share, presentation, and whiteboard marks recorded during the session. The file format will be .vp8 (with configuration options to alternatively create an .mp4 file as well).
Fully reimplemented whiteboard (tl;draw)
The whiteboard has been updated with TLdraw, a small appication which supports improved drawing features.
