[Freeswitch-users] WebRTC QoS

[Tihomir Culjaga]

hi Gonzalo,

thanks for your kind response.
I'm using verto and i was able to add

   audioParams: {
      googEchoCancellation: true,
      googAutoGainControl: true,
      googNoiseSuppression: true,
      googHighpassFilter: true,
      googTypingNoiseDetection: true,
      googEchoCancellation2: false,
      googAutoGainControl2: false,
      googDscp: true,
   },

within verto init.

well, my chrome still didn't want to mark the media packets :=)
i tried this on win7 and an older version of chrome (Version 49.0.2623.110 m)
i had hands on.
Im going to try this with latest chrome on both win10 and linux.

maybe this is going to work :=)


as for dscp rewriting, i can do it easy, but when chrome does a video
streaming ( e.g. youtube ) and makes a webrtc call, it should somehow give
priority to webrtc call bofore video striming :=)
Also, unfortunately, many clients are not be able to re-mark media packets
generated by webrtc call

we need to find a solution on the browser itself.
