Not working for windows to mac

[HirenOza]

Hello,

First of thank you very much for providing this wonderful demo.
I'm going to implement video call using webrtc with the help of this demo.
It works well but for some scenarios it doesn't work for me.

It will be glad if following scenarios where not working could be solved.
Windows - Windows : Working
Windows - Mac : Not Working

I'm using chrome browser in both windows and mac for this demo.

Thank you
