The end goal is to pass the analysis outputs of one encode as inputs to
the next encode(s), removing redundant work. The code that re-uses the
analysis hasn't been sent to the ML yet, but I'm pretty sure there's
wiggle-room for the 'slave' encoders to make decisions.  The initial
use-case for this is multi-rate fanout.
