Sort of.

Yes, "demux" plugins only apply to byte streams.
VLC has "access_demux" plugins in cases byte stream are inadequate or 
inconvenient an abstraction. Then it is not possible to adequately 
implement "access" and "demux" as separate and independent layers, and one 
single plugin takes care of both.
