Well, let's do it your way.

I too am not sure 100% there is no side effect whatsoever. The one thing
I know is that I have been using this patch for a while on many
different formats as a rather basic user (no fancy vout-filter and so
on), and it works fine.

I also think the vout architecture is well designed once you get to know
how it is done (only missing thing is a good doc to start with). And my
conviction is that width and height are never a problem (proof is
resizing is done at the vout level for x11 for example). Chroma has not
been a problem either in my tests (chroma conversion is also managed on
the fly when required), but I am less certain of all the implications.
