I would like to recommand using rpicamsrc from 
https://github.com/thaytan/gst-rpicamsrc . It's more efficient.

VP8 is a video codec, it's not going to help you with audio. What you
should do is simply to capture audio, encode it the way you want (like
opusenc) RTP payload it and send it over it's own port. I'm not sure
if/how janus will figure-out, I support you are crafting an SDP ?
