No. Inside the SBC stream the endianess is clearly defined (as much
endianess as is left) and as long as the encoder got it right on the
encoding side you will be fine. The endianess that comes out of the
decoder has mostly nothing to do with SBC but only with what the
programmer wants. 

So yes, we'd either have to define the interface so that our
decoder/encoder only generates/accepts big or little endian data and it
is up to the application to convert as necessary, or that choice must be
made a runtime configurable parameter of the functions.
