So, what's the right way for supporting Ogg File Format for both
Audio and Video Codecs reusing the most?
QuickTime provides an import and export components (eat/spit
components) that are designed to translate a file to/from QT's
movie file format. With these components, you would be able to read/
write ogg files with the QT APIs and applications.
It really depends on what you want, what your common usage scenario
is, the users you want to support, how much time/work you want to
do, etc.
The common usage is Ogg CODEC player in MacOsX. As you know, Ogg
support with QuickTime 7 has been broken. I have been trying to hack
on the qtcomponent [1] with no success at all. Indeed, without a
serious list of API/Functional changes from 6 to 7 ( a real
changelog ), it's quite difficult imaging what happened. I haven't
followed all discussion about this topic, and no one seems to go
further.
The only conclusion was that a new AFC should be implemented. So, I
have started to study the possibilities for the future. Ogg vorbis
should be supported natively by MacOsX.
The objective of this OSS project is that Ogg Vorbis should be usable
in MacOsX within usual applications ( iTunes, QuickTime and so ). And
that should occur in the less time as possible, and besides that,
resources of programmers (powerman) are really limited ( just me at
the moment in Just For Fun mode ). The idea, is that future codecs
could be implemented easily for Video too, reusing this work. So,
which would be the best option?
BTW: I'm quite confident that the actual qtcomponent could work in
Qt7 with minimal set of changes, but it's difficult for me to do that
as I haven't experienced with Qt6 API before. I was willing having
Qt6 and Qt7 both installed and having the possibility of launching
one of them each time so I could compare the behaviors. But I don't
know if that it's even possible.

Thanks you for the help and the interest.
