For my edification, what is the situation when you have a single  mediastream split over multiple ICE machines?  Is that because there are multiple interfaces available?

Right - I would suggest we have the single API from Option A, which I think is good enough in most cases, plus an API to get per-transport state if you need more info.


Note that tracks are not tied to ICE machines or components. You can have multiple MediaStreams on a single ICE machine, or a single MediaStream split between multiple ICE machines.

That’s what I was wondering about too.  (Could the transport objects be tied to tracks?)  You could fire events for the state changes on each transport object/state machine, and still have a very simple higher-level conbined state and query API (as in Option B) at the PeerConnection level.  Developers who only wanted to know when things got started and when everything got finished could use the PeerConnection API.  Developers who wanted to manage at a lower level could use the events at the individual ICE machine level.

I'll be there.


I'd also like to propose an Option C, where we have a list of read-only transport objects (1 for each machine), where each transport has a state as in Option A. This would avoid the issues you mention with Option A.

  Just asking out of curiosity:  when you have multiple ICE state
machines, do they correspond to the different tracks in the
PeerConnection, or is the mapping more complex than that?

I want to talk about ICE states a bit as this has been slowing me down.
I set up a bridge for tomorrow at 8 am pacific.  If anyone wants to join
me, I want to talk about the two proposals in the attached slides. If no
one cares, I will just talk to my imaginary friends about making
imaginary progress.
