We are running a recent version of licode to record video from Chrome (Version  
44.0.2403.130). An issue that we are currently facing is the video quality  
is bad when on wifi. See attached screenshots. The problem is  
reproducible on Android tablets and Mac OSX over WIFI.

The video constraints we are using:

mandatory: {minWidth:320, maxWidth:640, minHeight:240, maxHeight:480}

I have tried adjusting the bandwidth settings in the licode\_config.js

config.erizoController.defaultVideoBW = 1500; //default value: 300  
config.erizoController.maxVideoBW = 3000; //default value: 300

This seems to function as expected because it sets the b= param in the SDP  
to b=AS:3000, but Chrome doesn’t seem to listen to this property:

What other things can we try to improve the quality of the video over a  
wireless network?
