Is it true that a stream of constant exact zeros input will result in
a very very low bit rate out?  (If not make it so.)

In that case it is "easy" to write a filter for the input that
squelches at whatever level is appropriate to your application,
and it seems obvious to me that that is the Right Way to do it.
