Can't establish simulcast on BBB 3.0

[Adrián Pérez Aguilar]

Dear Community,

I'm currently experiencing issues with webcam streaming in a BigBlueButton (BBB) meeting. I’ve deployed a BBB 3.0 server along with Greenlight 3.0 in a private network for testing and research purposes.

The installation was done using the following command:

wget -qO- https://raw.githubusercontent.com/bigbluebutton/bbb-install/v3.0.x-release/bbb-install.sh | bash -s -- -w -v jammy-300 -s bbb.uma.internal -d -g

After resolving some initial setup issues, the platform is now fully operational. However, during meetings, I’ve encountered anomalies with webcam video reception. Upon investigation, it appears the problem stems from the transmitting client not sending multiple video stream qualities (simulcast), which seems to be affecting the viewing experience.

As shown in the attached screenshot, only a single quality stream is being transmitted, which may be causing compatibility or performance issues on the receiving end.

Finally, to double check if BBB 3.0 can do simulcast (I was 99.99% sure because I've read posts about it) I created a meeting using the public bigbluebutton server (https://demo.bigbluebutton.org/) and I could see in that case that the emisor sends multiple streams in parallel, as you can see here:

I used the chrome://webrtc-internals/ tool from Chrome to see this kind of information.

At this point, can someone help me on how to configure my server? Is there anything I missconfigured? 

Any help is more than welcome :)

Thank you!
