@ShijunS has it I think.  This is information that either the UA 
knows, or it's in a grey area.

Let's say that the UA didn't know, because it's coming from a video 
capture source that only provides the bits.  I would assume that it's 
going to surface as a camera in that case and be treated accordingly.

What you are looking for, I suspect, is a way to hint to 
RTCPeerConnection that a particular track should be encoded with a 
certain bias.  Like this sort of thing (from handbrake):

That's a tricky thing to get right.  LATER sounds right.
