The thing is that, bearing in mind the firing of the events can be delayed,
they're not perfectly accurate anyway. So are you saying that in typical
implementations, there *has to be* a long (order of seconds, I guess) delay
between calling pause() and recording actually pausing? And ditto for
resuming and stopping?

Then I think we should have a specific API for that which allows the app to
determine which track(s) aren't being recorded. It could be a specific
unsupportedtrack event, or we could let the app listen for the addition of
a new track, and provide an API on the StreamRecorder to check whether a
MediaStreamTrack is being recorded by the recording. Maybe the latter is
better since it would also be useful for the case where a newly-created
StreamRecorder can't record all the existing tracks.
