  Ok, you are pushing AVOption usage. Fine with me.

  As I asked before, I am not clear about the second part
adding a new function to the API should be API compatible,
and ABI compatible too, so changing the second component is
meant to be ABI compatible?

  If so i should mention that explicitly for clarity.

  Also my previous argumentation was flawed because of
me not taking into account that AVOption solves the
problems with the many ABI incompatible changes.

  Also could it be that your answer to that part of my
mail vanished somehow? You normally write [...] if you
skip parts.
