I can't say I'm all that surpised, this is not something that was
designed to work.
That leaves you two options:
a) Debug the problem, come up with a fix and send a patch.
b) Work around it.
be nice to add a sf_reset() function or a SF_RESET
sf_command()
parameter.
What problem does that fix? Do you even know if there is a problem? [ If you meant I should test the sf_seek() trick first
-- I doubt that
testing a few sf_seek()s on a few FLAC files will reliably establish
whether sf_seek() really does reset all encoder and decoder structure
under all circumstances. Especially since you said you weren't sure
yourself. ]
The problem you face is difficult enough with file formats that are
supported natively by libsndfile. It will be much more difficult for
the formats that require external libraries because the fix may
require fixes in libFLAC, libogg or libvorbis.
