Activities: BigBlueButtonBN

Integrate BigBlueButton within Moodle - including record and playback of sessions.
Moodle 2.6, 2.7, 2.8

BigBlueButton is an open source web conferencing system for distance education.  The goal of the project is to enable universities, colleges, and K12 to delivery a high-quality learning experience to remote students.

BigBlueButton supports real-time sharing of slides (including whiteboard), audio, video, chat, and desktops.  It also record lectures for later playback, specifically the slides + audio + chat (see release notes).

The BigBlueButton project was started in 2007 by Blindside Networks.  In addition our work on BigBlueButton core, we created this Moodle 2.x activity module so you can fully leverage BigBlueButton's capabilities from within your courses.

This module enables you to:

  • Create multiple activity links to on-line sessions within a course
  • Restrict students from joining a session until a teacher (moderator) joins the session
  • Launch BigBlueButton in a separate window
  • Create a custom welcome message that appears at the top of the chat window when joining the session
  • Specify join open/close dates for the session that appears in the Moodle's calendar
  • Record a session (requires BigBlueButton 0.8 or later)
  • Access and mange recordings (requires installation of recordingsbn)

The following YouTube video to demonstrate how to install and use this module.

Note: The video shows uncompressing a single ZIP file that contains two modules: mod/bigbluebuttonbn (create BigBlueButton activity links) and mod/recordingsbn (access recordings).  This is euqivalent to installing both bigbluebuttonbn and recordingsbn.

The BigBlueButtonBN module works out-of-the-box with, a BigBlueButton server that Blindside Networks maintains for the community to help test your installation with BigBlueButton.

    Hi Pascal,

    It looks to me as an issue with your BigBlueButton server. Having the demo page on top does not mean that your server is working.

    Open a tread in the forum and I will follow up with you.

    Hi Santhosh Samban,

    If you are using test-install most likely the server was not working at the time you run your "test".

    If you ask for help please include the versions you have for both, moodle and the plugin. And also, we ask people to use the forums when looking for help, so please please please do that instead of using the plugin page.

    Most of the questions have been responded already and there are more people than the developers that can help you there.

    I have tried some basic functions of Bigbluebutton, so far it looks pretty cool.

    However there is one thing I want to ask. Is there any way to automatically set up recording on when Teacher start the webinar session? Because currently it seems after 0.9 version the recording function become a small button that defaultly off since the webinar started. For teachers who don't know Bigbluebutton they might easy forget about this recording function.

    So is there any way to defaultly switch it on when the webinar started?

    Hi Sai,

    The start/stop recording button is a long time asked feature that we were just able to include in 0.9 after a large amount of changes in the core. This offers the advantage that moderatos can chose what is going to be recorded and what is going to be out of recrds, and also no matter if the attendees get into the session 1 hour before or they leave 3 hours after, the recording will not have that long white space before and after the real content starts.

    Believe me once the user get used they will stop complaining. It is not for sure yet, but we are considering removing the recording parameters from the activity configuration since it is actually no longer required.

    If you have your own BigBlueButton server there are some parameters you need to change. You can find more information or help by using the BigBlueButton google groups.!forum/bigbluebutton-setup

    Hi Jesus,

    Thank you for the answer, I got your point and I agreed with that.

    There is another question I want to ask: how many attendees Big blue button can handle at one time? 25 or 50 or more? Does it able to handle big number of attendees like 500 if the server is really good? If you can provide an idea of what kind of server standard can handle how many attendees, that would be really helpful.

    Really appreciate your help.

    Thank you,
    Sai Duan

    Hi Jesus,

    I have read some posts which talking about have multi-session at the same time, like 6*50 = 300, but I was wonder how it can be down in Moodle plugin? For one presenter is it possible that in Moodle we set only one course but have multi-sessions for different attendees? How could it be achieved?

    Thank you,
    Sai Duan

    Hello Jesus,
    I just discovered this plugin and it really looks like the one we were looking for. Before starting using it, and inviting people to the class, I'm just wondering about how many users can join the online session.. Is there a limit given by BBB or it depends on something else?
