How to record Canvas and microphone (Game Recorder)

Hello, I need record canvas and microphone at the same time, I try to using the Game Recorder plugin but i do not find how do this, I try do this by script and this works good, but when i try share the video in WhatsApp this says video format not supported. This works in Iphone but in android not because this exports is in .webm format.This is my script:

The built-in Game Recorder object should already support this. If you specify an audio format when starting a recording, it records the Audio plugin's output if it's in the project. If you have used UserMedia to request microphone input and routed that to an Audio tag, it will come out the Audio output too.

Hello!.

Thanks by reply, yes I was try to do this, but the mic has an bad effect, and I add a muted effect to the mic but the mic audio is not exported with the video, I not found a check for ignore muted audio. Thanks!

This is an example:

I select this:

And I also did this:

I did this so that the audio from the microphone is not returned and causes that echo distortion effect. But I do need it to be heard in the recording result.

Thank you very much for your prompt response.
