A few questions for those working on the media format improvements:

2) Cached formats: who is supposed to define these things? Thanks to
Corey's patches compilation succeeds, but linking fails big time. I'm

I don't think anything, yet. Something in the core should though.
There's something of a chicken& egg problem here.
We can't generate a format properly until we have the codec. Those
codecs are loadable modules: they may be present, they may not ever be
present. And they may load late in the startup sequence.
Not completely. Built-in codecs are initialized in the core at a
specific point, it is guaranteed for them to exist after that. If you
create formats using them and cache them after that then all is well.
What you can't do is exactly what you said - create a cached format for
a codec that isn't loaded. Heck, it may not never be loaded if you allow
that. For that case I would expect that a single module would register
the codec and also create the cached format.
