Hi.

AFAIK, compressed output is generally determined solely by input.
(Exception: Ogg Vorbis files have random serial numbers which can
result in different compressed output with identical input material,
but if you force all encodes to have the same serial number, then
identical input results in identical output.)

I don't think FLAC encoding uses serial numbers, so if you're using
one encoder to encode identical files, you should get identical
results.
