Shouldn't this enclose more of the includes above?

This is conceptually weird for me. The category variable should "live" in Base.cpp and be initialized here since it's the superclass. I understand you really want to get rid of this method but IMHO, I think we should keep a very small version of it because of the initialization of this variable, keep the _CATEGORY( here and have the _CATEGORY_EXTERN( in the subclass.

I don't think it's necessary because MSE, MediaStream and EME are already declared as depending on VIDEO in WebKitFeatures.cmake.

The MSE player already uses its own debug category. Maybe we could have a separate category for the base player after all :) Anyway, for the time being i'll keep a small init function then.
