At the moment there is no standard interface to access supported
input and output types... but then: regular Python functions or
methods also don't provide such functionality, so no surprise
there ;-)

It's mostly a matter of specifying the supported type
combinations in the codec documentation.

BTW: What would be a use case where you'd want to
programmatically access such information before calling
the codec ?
