is it possible to publish audio AND video to server using this?

hi, i am having a really hard time currently figuring out how to get audio AND video from browser through https reverse proxy and into liquidsoap.

i would like as few moving parts as possible and therefore this webcast.js thingy seems awesome, but the lack of documentation makes it hard for me to get it to work

@toots do you know if the webcast.js protocol allows simultaneous audio and video?
