Well then we can think about fixing pause/frame accurate/last seconds 
not being played errors (and all that are related to current structure).

I think it is premature to do that now. It is my feeling that there are 
  still things (fundamentally) very wrong or broken in git. Let us focus 
on fixing that first, before rewrite internal module ABI's. Which will 
definitely destabilize vlc more (at least temporarily) and make it 
harder to get git in a sensible state.

First RFC then remapping and rewritting (has my preference).

No problem. Just my 2cts.
