Is it possible to change the Audio Codec used?

[sarinrohan]

While running the app on my phone, when I check the logs on Eclipse, I find that it sets the audio codec as Opus at 32kbits. Since the internet connection I am using is pretty poor, is it possible to adjust the SendCodec bitrate to a lower value in your app for better audio?

Also, would it help to use the compiled library for Google's WebRTCDemo and create a VoiceEngine and simply edit the sendcodec?

Thanks.

Sorry, I really don't know how to change the codec. You should check the
WebRTC native APIs.

I tried to change stuff. It's there in webrtcvoiceengine.cc.

Though can you let me know what changes you made to the WebRTC Java libraries before compiling them? After I recompile, a few methods such as InitializeAndroidGlobals gives me an error in AndroidRTC.

I haven't made any changes to the WebRTC Java libraries, but it's an old
version.
That's an odd error, initialiseAndroidGlobals should still work :

Found a workaround. Passing other 2 parameters as True to initialiseAndroidGlobals works. Its something to do with initialising audio and video streams. It was updated in the newer releases.

Good to know thanks !

Hey,
i have created an voice calling app(WebRTC) in android.it was working fine but there is noise and echo in the call. Is there any way to reduce echo cancellation and noise cancellation in android??.i have used your repository for building my application.

Hi, I've updated the libjingle and you should now be able to change audio and video codecs (as well as some other parameters).
