Is it able to get the currently active speaker in a webrtc sfu conference?
There are events which can be raised over AMI to show who is talking, otherwise you would need to be more specific in what exactly you are wanting to do and how.
It’s enough to know who’s speaking in a conference. It’s more appreciate if client can get a notification of its change through websocket. Is it possible?
Yes. Run an AMI application on a fixed server that than talks to your web clients over websockets.
Got it, I will have a try, thanks for your helps.
