You need to do it everywhere data is passed between filters. So it will 
matter for the output of the encoder and output of each stream from the 
demuxer.

But it's not a big issue for the output of the encoder since you typically 
can have less buffers (like only 2 or 3), so it doesn't really matter if 
those buffers are exceedingly large.

So it's mainly the outputs of the demux and thus the input to the decoder 
(which both share the same allocataion of samples) where you have a moderate 
amount of samples and having extremely oversized samples becomes expensive.

Zen.
