Yes, KFilterBase itself is no longer part of the public API [except when writing
a new filter].
It was a messy API of mine, with rather confusing ownership semantics
for the KFilterBase instance, which is now fully handled by KFilterDev and hidden

Forget about setting a KFilterBase :-)

Yes, this is the one you want.
Why is it a problem that it "needs the mimetype"? You said the kde3 code uses
KFilterBase::findFilterByMimeType() so surely it knows the mimetype.
Instead of keeping a filterbase around until the KFilterDev creation,
just keep around the mimetype and call the above method. I.e. port
KFilterDev filter(filterBase, false);
QIODevice* filter = KFilterDev::device(&comprFile, mimeType, false);
