Have you considered having seprate stats object for audio and video?

Yes, the plan is have stats collection be a RawEventSubscriber implementation.
In LoggingImpl, if stats collection is enabled, then install separate
StatsSubscriber objects for video and audio events. But that's for a later CL.
In this CL I just want to get the JS API working without making too much
changes.

   GenericStatsMap GetGenericStatsData() const;
 
   // Reset stats logging data.
