The platform interface needs to be cleaned up, we don't need some left over chrome-isms, and some of the code can stand a bit of polishing.

Seems like this should be in MediaStreamCenter and should override the return of MediaStreamCenter::instance().

Then, this wouldn't be necessary.

Ditto.

> +void MediaStreamTrack::trackEnded()

Why not MediaStreamTrack::trackDidEnd()? Especially since the client method was renamed from trackEnded() to trackDidEnd().

Bug #? :-)

One more.
