I've been discussing this over at the gstreamer list and I have some
more info.

Ideally it's a system function, but I'm not seeing a way to pull that off.

gstreamer has no ipc equivalent to the alsa dmix, so a pure gst
implementation will not mix multiple apps down to one stream.

that is unless you help write the ipc mixer for gst :)

sadly, gst would really be a great implementation (moving the encoder
into a hotpluggable module, allowing for late binding on choosing the
encoder, possibly a way to redirect a stream in progress to the set) but
the lack of a way to mix multiple apps is not great.
