Record audio from two microphone and video from one webcam and mux using FFMPEG [closed]

Question

Iam trying to mux audio from two different microphones and video from webcam using ffmpeg in linux.
I used the following code
ffmpeg -f video4linux2 -s 320x240 -i /dev/video0 -f alsa -ac 1 -i hw:1,0 -acodec libmp3lame -ab 96k camera.mp4
it works for muxing audio from one microphone and video from one webcam

I went through forums and googled for an hour without any positive result.

So, the question is i need to mux two audio from microphones and one video from webcam and produce a video output with two audio tracks.

Thanks
