Re: [Linphone-developers] no built-in echo canceller on samsung GT-N7100?

[Erwan Croze]

Hello,

There a file in mediastreamer2 project:

mediastreamer2/src/audiofilters/devices.c

In this file, there are a list a device and option for each of them, you 
can try to enable echo canceller here.

Best regards,
