I am installing Intel CS for WebRTC 4.2.1 on Ubuntu.
And I set views to  from management console to run server for SFU mode.
I think that when I turn server mode to SFU mode, the server does not do the mixing streams, but do the transcoding to forward the stream.
Am I right?
If I am right, is there any way not to transcode stream on SFU mode?
You can turn `transcoding` off or avoid starting audio/video agent.
