Introduction


Key features of the Tiki & BigBlueButton integration
  • 1-click login into BigBlueButton using Tiki user system
  • Various permissions on the BigBlueButton session via Tiki's permission and group system
  • Listing BigBlueButton recordings in Tiki.

Tiki 5.0 supports BBB 0.64, and Tiki 5.1 (and later) supports both BBB .64 and .7
Tiki 8.0 adds support for the new features of BigBlueButton 0.8, such as record and playback. (and continues to support previous versions of BBB)
Tiki 9.0 added a new permission to allow showing the recordings to users without the permission to join the meeting ( tiki_p_bigbluebutton_view_rec )
Tiki 10.0 admins can now delete recordings

BigBlueButton users need to have Flash. For the server, a dedicated server is needed with 2Gb of physical RAM (not as swap in a virtual machine frmo the host). BigBlueButton is licensed LGPL, just like Tiki.

How to use BBB

General comments

You need to have the plugin for the flashplayer properly installed in your browser in order to use BigBlueButton.
This can be tricky for certain combinations of operating system and browser. For instance, if you experience any unexpected crash of your flash plugin at the first attempt to connect to bbb (for instance if you have a GNU/Linux based operating system 64 bits, and installed flashplugin from the system repositories), you can try these steps that use to fix your flashplugin setup:
  • Use Mozilla Firefox as browser, and install on it this extension: Flash-Aid:
  • Choose the installation of new icon created by the extension, and select the "Quick Mode > Install beta flash"
    • This will guide you through the installation. Restart firefox as requested at the end.
  • Go back to your BBB installation and try connecting again.

In addition, if you can't click at the window to accept the remote server to use your wecam and microphone, you can manually enable that by means of:

BBB 0.81

Changes:
  • Visual indication of who is talking
  • Custom and predefined layouts
  • Keyboard shortcuts
  • Webcams, Screensharing and Notes taken in the Whiteboard shown also in the playback
  • Playback: You can point to specific time/part of the recorded session
    • Add &t=XXmYYs to the URL of the recorded playback (XX for minutes, YY for seconds)
  • Playback: You can switch the main view by clicking the "opposite directions" arrow icon to switch the presentation/webcam views
  • interface translated to many more languages



BBB 0.90

Changes:
  • Start/Stop Button for Recording: Moderators can now mark segments of the class for later playback.
  • Improved Audio: BigBlueButton now takes advantage of the web real-time communications (WebRTC) framework built into FireFox and Chrome to give users higher quality, lower latency audio.
  • Microphone Check: BigBlueButton now gives every user a chance to check their microphone before entering the session, ensuring when they enter the session they are ready to participate.
  • Listen Only Mode: Users without a microphone can join audio in 'Listen Only' mode. In this mode, BigBlueButton displays a speaker icon next to their name letting everyone know they can hear (but not speak).
  • Updated tips:
    • Add ?t=XXmYYs to the URL of the recorded playback (XX for minutes, YY for seconds)

Videos about Tiki & BBB


The Tiki community Dogfoods BigBlueButton at tiki.org/live.






The Tiki community has been testing BigBlueButton for this type of live collaboration and members of the community have decided to enter in a long-term integration partnership to maintain it as a Tiki feature, starting in Tiki5.

About the integration

Similar to Kaltura, BigBlueButton needs to be installed alongside Tiki (can be on a different physical server). Each project remains standalone, and we'll collaborate to continuously improve the glueware between the two.

At first, Single Sign On, but over time, we expect that many features will meld. The Tiki community will DogFood extensively. Tiki8 integrated the new record and playback features from BigBlueButton 0.8


Set-up


Before setting up the tiki integration, the BigBlueButton server stack must be installed. Detailed instructions are provided for multiple platforms. However, using the provided virtual machine is the easiest way to go. Also note that there are heavy bandwidth requirements.

To enable the integration in tiki, you need the following information:


Creating rooms

The user interface for BigBlueButton goes through a wiki plugin. You can use it in wiki pages or most wiki-parsed text areas. To schedule meetings on a calendar, you can use the calendar feature.

Sample
{bigbluebutton name=My Meeting Room}


If the server location was configured successfully, the BigBlueButton logo will appear. A create button will be proposed to create the new room (a permission is required, but administrators have all permissions). If the salt was set-up correctly, you will be redirected to the meeting room.

Going back to the plugin, you can set-up the permissions to select who can join the meeting room or moderate it.

More info at PluginBigBlueButton

Asterisk

To use the voip feature when using a room name instead of a number:

Change
open the config:
sudo nano /etc/asterisk/bbb_extensions.conf
then replace:
exten => _XXXX.,1,Playback(conf-placeintoconf)
with:
exten => _.,1,Playback(conf-placeintoconf)
and replace:
exten = _XXXX.,n,Konference(${EXTEN},H)
with:
exten = _.,n,Konference(${EXTEN},H)

Than reboot the Big Blue Button server with bbb-conf --restart.

note: if you don't have nano installed use sudo apt-get install nano


Uses

This will help with several related but slightly different uses.

Webinars / e-learning

Scheduled, live, interactive, one to many delivery of knowledge. The session could be one time (webinar) or an ongoing course with a regular schedule. This is BigBlueButton's core objective "our focus is to make the best web conferencing system for distance education."

Remote support

A visitor clicks a link on a brochure website and is put in contact with a representative of the organization. This is similar to Tiki's Live Support feature (ad hoc 1 on 1 chat help support), but with BigBlueButton's feature set, there are way more possibilities (screen sharing, co-browsing, etc.)

Team meetings

Useful for Teams to meet & coordinate. These are typically scheduled (for instance with PluginConvene since Tiki9 and Tiki Calendar) and have an agenda (presumably in a wiki page). Ideally, decisions are recorded (presumably in a wiki page). Everyone can be on audio & webcam. Headsets are recommended.

Broadcasting live events

This will be useful during TikiFests. A projector can be setup at the live event so all participants can see everyone and follow the discussion on the chat. Typically, remote participants can listen in, but will respond in the text chat. (Just because of logistics and ambient noise).

Community chat

This is the place to go to hang out with "everyone". It's on 24/7 and can be idle for long whiles. It should be logged as a lot of knowledge, answers and links are shared there. Quick "decisions" are often taken there as well (ask a quick question and if everyone seems ok with it, it must be ok). Even if some users may be identified with special rights (ex.: ops), the room is very p2p. It's possible to break out of the room into a smaller one for a short, focused or private discussion. Historically, we use irc.tiki.org but we could eventually develop an IRC to BigBlueButton gateway.


Surveillance camera

Typically a video stream which can be monitored and recorded.
