Does Intel CS for WebRTC framework supports SFU?

[Chandramouli_P]

Hello, I am just wondering to know that whether Intel CS for WebRTC framework supports SFU (Selective Forwarding Unit) to setting up the conference or not? I haven't noticed anywhere about the SFU in the documentation. All I see is Peer-to-Peer and MCU only. Could anybody please confirm? Thank you. Best Regards, Chandramouli.

Yes you can use as SFU turning mix =false

Thanks Kiran for the answer. Yes, you can set mix=false to use WebRTC server as pure SFU mode in previous version. In latest 4.1 version, you can remove views in room configuration then mixer will not be launched and server will run as pure SFU mode.

Hello, I am using latest i.e V4.1 server side MCU sdk sample provided by ICS WebRtc. In which I have created a room using management console in the sampleService and removed the views from it. But, when I tried to join this room then I got the 500 status from server side. If views is not empty in the room then everything is working fine. Can anyone help me to change MCU Mode to SFU Mode.

Thanks in advance.

Did you see any error message on server log and chrome console? To use SFU mode only, you just need to delete view info in room, please provide related error log in server and chrome console for we cannot reproduce it.

Hi, Jaiswal, there is a bug in 4.1 management console that you cannot delete view in 3300/console. You can call restful API to set view in room to [] to disable mixer in conference and use pure SFU mode only.
