[Freeswitch-users] OPUS and CPU load

[Quan Huo Sheng]

I just want to study a successful case for the Webrtc demo (using media mode) in the chapter 6 of book “FreeSwitch 1.6 Cookbook” which uses sip.js (sip-0.7.0.js) in Chrome.

So far I fail until now. Please refer to the  thread “Webrtc [err] mod_sofia.c 2299 codec negotiation error. Sdp”

Can someone explain why sip would be preferred in this scenario?  Is there any real reason?

Hi;

I want to set up Webrtc Demo using freeswitch with media switching or media transcode. Setup is chrome (sip.js) ->fs->chrome (sip.js), but end up with fail.
Can you share your successful case using Webrtc + opus. (SIP preferred to Verto as signal).


Thanks

In my tests OPUS transcoding seems to consume 5-6 times more CPU then G.711 or G.722.

I've seen estimates that opus is up to twice as heavy as g729.  webrtc encryption adds some (although not huge) load on top of that.  20 opus sessions per cpu seems low, are these particularly slow processors or virtual processors?
