that's the encoder's own stuff, the ACM SDK doesn't know about 'frames', it 
just tells the codec 'here, take this buffer, I want you to decode in this 
other buffer that's allocated for n samples', to which the codec can say 'ok 
I just decoded y samples, here's the result', or 'ok I decoded them, but 
that didn't produce any samples', etc.

I don't see how this could be a problem for the codec. There wasn't enough 
samples for 1 frame? it doesn't matter, the codec can just buffer that, and 
report that it couldn't decode the samples. The next chunk, it might have 
enough samples.
