Re: [webrtc-stats] Unclear which framerate "framePerSecond" represents

I must correct myself: FrameRate (nominal) attaches to  
RTCMediaStreamTrackStats. There are no frame-related stats connected 
to RTPStreams.

MediaStreamTracks are unidirectional, so there's only one frame rate. 
Outgoing and incoming frame rates (if we have both) are on different 
tracks.
Stat values should normally not be averages - see the discussion at 
http://rawgit.com/w3c/webrtc-stats/master/webrtc-stats.html#guidelines-for-design-of-stats-objects
 (I don't think we've published a dated editor's draft since this was 
merged). We already have frame counts at multiple levels.
