Please, define "merge".  Sample questions:

Interleave specific sequences of bytes/frames (10 from input 0, 10 from 
input 1, ...)?
Specific order or as available?
If ordered, what to do with accumulated input from !n (where n is a port 
that has no data for some time)?
If as available, what policy for balancing input accumulation in output 
stream?

Provide a transport stream composed of the individual inputs, converting 
them to program streams (muxer)?

For audio-only mix the inputs to one output, like a multi-track studio 
mixer?

Something else?
