@ffdixon this will be really good feature. Not all the time we want to interact users with classroom. Sometime we just want them to see the activities only. Really good feature to have here :) |

do you mean capture the headless browser screen,? |

Hi Jossef,
and maybe replace the current recording creation method, that is pretty
complicated to support.
We don't have plans to replace the current recording format. For example,
you could have 20 meetings of 5 people each running on a BigBlueButton
server, and by simply capturing the events, there is no overhead to the
recordings. Later, after each session is finished, the record and
processing scripts use the events and captured media (audio, video, screen
share, and presentations) to create the recording for each meeting.
This gives a *lot* of flexibility in how the recording looks (as we've done
with the different formats bbb-playback-presentation,
bbb-playback-screenshare, bbb-playback-podcast) and the ability to extract
meeting analytics from the events (attendance and participation).
While capturing the screen and streaming it is good for broadcasting to a
CDN, in the above example you would need a second server (or two) to span
20 Chrome processes to record the above 20 meetings. And, if one of these
processes doesn't start, you don't get a recording.
So, we'll definitely be keeping the current system in place while we look
at adding to it the ability to broadcast a session via a CDN. The record
and playback architecture may take us more development effort to maintain
and enhance, such as any event we want to be recorded must be faithfully
reproduced in the recording by the scripts, but we believe the benefits
outweigh the efforts.
Regards,.... Fred

they will all be a part of the strearm going to CDN ?
if so, this strearm can be used to create a "1 video file" recording
format that can be downloaded.

That is right Fred. It will indeed require too much server resources. |
|
Does the room have a final rtmp signal that can be taken to CDN with real time audio and video? example: rtmp: // xxxx: 1935 / room_number thanks |
It does not, but one could write a virtual client (FireFox running within a virtual frame buffer such as That's basically the outline of how to implement this feature. |
|
maybe the following can help: |
|
Thanks, we've been working with WebRTC for many years now with BigBlueButton. We have a good idea of how to implement this feature, but right now our priority is to continue to improve the core of BigBlueButton itself. See http://docs.bigbluebutton.org/support/faq.html#when-will-feature-x-be-implemented |
Thanks for starting this thread. At the school I've setup this project for, they have certain classes that get broadcasted to hundreds of students simultaneously who are essentially listeners only (even more now due to covid-19). For the elderly, it's difficult for them to figure out the intricacies of the system and they consistently have trouble joining. It would be much easier for them if we could have a "live" page on the website where they could simply point their browser to and watch the class. I very much do understand the limitations on your time. Unfortunately this is beyond my personal skillset. Is there any interest in setting up a bounty for this feature that perhaps a few of us can contribute to? |
@ffdixon thanks you. I did something like this here: https://github.com/jibon57/bbb-recorder here I am getting |
|
I've managed to push audio only from bbb conference to wowza via rtmp by enabling mod_av in freeswitch. Don't know how to move on from here and include the whole conference (video, shares, as it is seen by a web client) On the other hand is WebRTC also an option now that is enabled in wowza? Any hint on these kind of publishings would be appreciated. |
|
Although I am not expert on this side but I was able to send screen sharing over |
|
Screen sharing and rtmp sending is best done with OBS. |
|
@bilias in my solution I am using ubuntu server & sending one student as bot. But yes, bit complicated. |
|
Hello together, i just want to mention that this feature would be really appreciated 👍 at the moment we hosting sessions with over 100 people. we also streched this now to 150 but we are scared to scale it more (especially because of the client side where we have no experience) such a feature would be awesome. we used obs-studio for youtube/facebook but it is a lot of work. |
|
It seems Jitsi does a good job with this, in terms of allowing the user to enter a key for youtube live for the meeting to re-stream there. I believe that their Jibri service does it exactly the way you did, @jibon57. |
|
@Lukas2000 you can give a try my implementation from here: https://github.com/jibon57/bbb-recorder but has few limitation left. Will be happy if someone contribute. |
|
This company solve the problem. https://elos.vc |
|
Would be nice if they contribute the code back to the community. |
|
There are guys from mconf.com - company behind elos.vc service. May they already pulled this funcionality back to the core BBB. |
|
We're working on increasing the (soft) limit for number of users in a session in the next release of BigBlueButton, which will be 2.3. We'd like to get to 150 comfortably, in which case they need for a live streaming solution goes down a bit more. |
This looks wonderful. Anyone have a contact there that they can speak to about contributing that code back to the community? Although the increased limit would definitely be nice, the issue has more to do with the inability for some (especially the elderly) to figure out the system at all. For them, it needs to be as simple as turning on the tv (or in this case, going to a page on the browser). |
|
Hi ... @ffdixon is there a scheduled date for 2.3 being released yet? And which changes are planed, that improve the limitation of usercounts? @jibon57 you say: "Sometime you may want to broadcast meeting via RTMP. I did some experiment on it & got success but not 100%. " Could you improve your results in the meantime and got a stable life streaming? Wouldn't it be interesting to use this captured stream to send it to all users as video instead of sending every videeo to every user? This would allow to have quite unlimited webcams active at the same time - wouldn't it? thanks |
|
@mtsonline i guess it depens how "stable" such a feature would be. when you have only one video then you missing features like draging webcams / making one specific webcam big and so one. |
|
Not cool, @shareefhiasat. Next time you reach out a company requesting information you intend to copy and paste to a public forum, make your intention clear. |
@fcecagno You are right, i felt its wrong, deleted it Sorry all. |

Hi everyone, want to comment on behalf of Mconf regarding the streaming feature we have on Elos, since it was mentioned here. We've been part of the BigBlueButton community since 2011, and during this period we had contributed back to the community in code and support, and we also built a business based on it, helping people and businesses in Brazil and abroad - we wrote a blog post a while back about BigBlueButton and Mconf (it's in Brazilian Portuguese but you can Google Translate it if you're interested): https://blog.elos.vc/a-historia-da-colaboracao-entre-mconf-e-bigbluebutton/. The streaming feature is a value added to our service, and at this moment we do not intend to contribute it to the open source, although we continue contributing back in many other ways. |
|
Due to some requests by users for user controlled streaming (via greenlight) I threw together a small orchestration around the existing docker container; Together with a small greenlight patch, this lets users enable streaming for their rooms themselves (Select 'stream this room' in the room-settings; Stream pops up under a fixed url.). Might be useful for somebody: https://github.com/ichdasich/bbb-stream-control |
|
Just fyi ... if that is of interest. We just had 591 people in one room ... at around 400/450 we had to switch Presenters-Video off (before that we had even two presenter videos running) and go with Audio-Only (and presentation) ... what (to our surprise) killed the server was when the presenter started a poll ... the server was pretty good 32 vCPU and 128 GB RAM ... so just to give you an idea ... spread out in multiple rooms (we had 20-30 presenters some rooms up to 100 visitors) the server was fine up to 300 users ... so I'd say that is virtually the limit for a normal server I guess ... at some point it makes no sense to run the chat etc. since ppl are only listening with a room of 500 ... also administration (kick users that do not behave) is pretty much a challenge scrolling name-lists ;) ... so I think if we would have had an easy option to stream the presentation, outside BBB, we would have done that! |
|
Take a look at stream control; If you combine that with your own streaming platform (not the static stuff in the examples), this can probably flow relatively easily and help you distribute load esp. for view-only events. |
|
Hello Everyone:
Would our beloved BBB being able to handle this? The Setup would be on a 18Core+HT Server with 128GB Ram. We were planning otherwise to distribute the meeting on to multiple (Smaller Spec-d thou) Servers for the Breakout-rooms.. Any Thoughts on this? |

Can we somehow take raw streams from the bbb meeting and broadcast them live to RTMP server as youtube live? |
There you go: https://github.com/lukas2511/bbb-streaming |
Whoa @lukas2511 nice work! That's very promising! Maybe that's the right direction. Is anyone using it? I don't think it was mentioned, so I say it: We have a BountySource prize for BBB+RTMPPrize amount: 200 $ (Ago 2021) Spoiler: there are plans to add more money to this Bounty to further encourage developments. Source: Italian Free and Open Source cultural associations. Other people might be encouraged to add some dirty money as well. Why people invest in this bug?At the moment lot of Free and Open Source communities are investing on BigBlueButton to handle conferences or webinars or school assemblies but BBB cannot scale to more and more than 100 viewers. That's why the ability to stream BBB via RTMP is useful: to allow thousands of viewers to join directly from their favorite social networks or from other places (e.g. hosting yourself an Some workarounds not yet mentioned:
Proposed goalThe goal is to avoid workarounds and have an way to do RTMP streaming directly from BBB. Basic functionality:
Bonus point:
Supermega-awesome bonus point:
Thank you again to @ffdixon for reporting this bug. Maybe it's a good time to set |
|
Isn't this basically covered by, e.g., https://github.com/lukas2511/bbb-streaming + bbb_stream_control, at least with greenlight? I mean, setting custom RTMP dst. should essentially be easy to patch into bbb_stream_control (which currently only supports self-hosting) |
You can also just give my streaming tool a join url, it doesn't need greenlight to enter. I'm going to continue work on this in the next few days, hopefully having it more stable and working with an up-to-date BBB version until the 20th so it can be used for FrOSCon |
|
Yeah, but i thought that this was also about having it integrated in the frontend, so users don't have to manually spawn the tool. :-) That's where the stream control stuff for GL is handy (https://github.com/ichdasich/bbb-stream-control) |
|
Here, I explained how to create a rtmp server ;) |
Could we set up an account with https://opencollective.com/ - who would do that? I am struggling to set up an account and not that geeky to grasp it all yet, but could work with someone to do it transparently. |
Awesome! If one of these commercial companies is available, can they send a salesperson's contact here, or right to |
|
@valerio-bozzolan You can contact Bob Teng at http://mynaparrot.com (Bob Teng [email protected]) - I recently wrote to him to try and figure this all out and how the community can get the updates his team has made for RTMP streaming etc. |
|
@FreeScholar I'm Jibon working in MynaParrot. Our RTMP solution is already open source. You can have a look from here: https://github.com/jibon57/bbb-recorder Also writing company's internal communication not fair to open in public community as you did in your post. |
|
Hi @jibon57 - I am one of your clients - nice to meet you here. Thank you so much for responding with details! The work you have done is excellent - hmmm, I get it now - the extra CPU/power is a barrier to a lot of people. I am not geeky enough to grasp the whole issue but I can see why it is problematic. I think it would be great if people with more knowledge can jump in on this and perhaps find a way to make this happen for BBB - perhaps a fork? That would get messy I think, but I do not know (I know the word 'fork' *lol) I edited my post and removed the email response from Bob. I think has response was on target though! |

a bounty program for the BigBlueButton RTMP project |
|
Hi Everyone, As @ffdixon explained, implementing a live streaming solution for BigBlueButton is not trivial, the bounty does reflect the efforts needed for a such project. On the one hand as @fcecagno mentioned it is an added value that makes the contributors companies stay healthy in the commercial support providers ecosystem, on the other hand thanks to Frictionless Solutions at RIADVICE we were able to trigger the development of an open-source platform that answers to this specific requirement, that solution name is https://github.com/spoutbreeze/spoutbreeze. The development so far is complex and there is a lot of components involved to make the integration smooth with BigBlueButton. Definitely it is going to be installed on different machine because it is risky to share the same resources of a BigBlueButton server for live video encoding. The solution is designed to be scalable and it contains a dashboard for a minimum administration and management. The discussions are open https://github.com/spoutbreeze/spoutbreeze/discussions, you will find all the information you need and of course all contributions are welcome to this project. |
|
@GhaziTriki looks/sounds promising :P |
|
Hi @lonesomewalker, RIADVICE is open to that but also looking for resources and brains to solve some of the issues we have. Feel free to contact me on my mail to discuss further. Check my github profile for my e-mail. |

From the bigbluebutton-dev mailing list:
|
|
@hex-m that is very interesting. Cudos for such a long waited feature for BBB. Could you please add a couple more details on your github
thanx |
|
@bilias i'm just relaying the message. Such questions should probably go to the mailing list or the issue tracker of the project. |
and others
BigBlueButton implements the core conferencing capabilities you would expect in a commercial web conferencing system (and gives them to you under an open source license).
The focus of the project is engagement with users. It does this by extending these core capabilities to give the presenter: multi-user whiteboard, shared notes, polling, breakout rooms.
This works well for small to medium-sized sessions, and we currently recommend using BigBlueButton for sessions of 100 users or less.
There are times, however, when you want to broadcast a session to much larger numbers of users. One way of achieving this would be to join a BigBlueButton session with a headless browser, capture the video and audio, and stream it to a CDN using RTMP.
If we give the instructor the ability to initiate such a broadcast and provide the CDN endpoint, then the presenter could still have engagement with the users that join via the BigBlueButton client, but also reach the users that are watching live on the CDN stream.
