[Spce-user] audio/video stream data through server

[yanzs]

Thanks again, Daniel, that is very helpful.

BTW, I also found that even without disabling rtpproxy, most data would 
be transfered directly between endpoints.
Following is the bandwidth test result of video call between two Jitsi 
clients.

rtpproxy enabled

    Figure 1. use_rtpproxy set as "Always with plain SDP"



rtpproxty disabled

    Figure 2. use_rtpproxy set as "Never"
