Just to clarify, my question was about the FLAC decoder itself, rather
than ffmpeg. I've built my own decoder around the flac.c file - using
my own FLAC parser and the bare minimum of support functions from ffmpeg
(namely the bitreading and golomb routines).
So I'm simply asking if flac.c itself (which decodes the data into
32-bit ints) is known to be able to handle 24-bit audio.
