I am concerned about what happens when input frame rate varies or 
takes a dip, since a VideoStreamTrack by definition doesn't give you a
 constant frame rate.

I think a related problem that is harder to solve is offline video 
recording (ref OfflineAudioContext), where an application could render
 as fast as possible but you'd still get a deterministic result from 
the recorder.

I think such a solution could be generic enough (supporting 
offline/non-offline) to be re-used for the use case you have here.

I guess I'm thinking of something like AudioWorklet but for 
timestamps/frames/audiobuffers. This would allow for the application 
to decide what to do when there are framerate changes.
